Well began taking county water at 75 gpm shortly after being secured last night. Pulled out of the hole. Laid down 5 3/4" mill. Made up 6" mill and 7" casing scraper. Ran in the hole to obstruction at 2162'. (A 7" DV collar was used in the 1979 workover at 2161,). Attempted to work through obstruction with out success. Pulled out of hole and laid down tools. Had no indication that the casing scraper had encountered an obstruction. The 6" mill that had been past this place several times before must have encountered the obstruction. Well seems to be indicating that It is starting to unravel and the problems are Increasing in frequency. Made up 7" EZSV and setting tool. Ran in hole to 2990' and set EZSV with no problems. Stabbed through EZSV and performed Injection test. Had communication back to surface. This indicates that the fluid is comming back up the well bore past or around the EZSV. Closed pipe rams and pumped 3 1/2 barrels per minute at 800 psi, same rate as previous test, indication that communication with the reservoir has not been interrupted. Secured for the night on county water at 75 gpm.

RE: Request for Permit to Plug and Abandon HGP-A Well

Dear Mr. Wilson:

The Natural Energy Laboratory of Hawaii Authority (NEIRA) is the successor interest to the Research Corporation of the University of Hawaii under the State of Hawaii Department of Land and Natural Resources Geothermal Resources Mining Lease No. S-4602 entered into between the State of Hawaii, Lessor, and the Research Corporation of the University of Hawaii on June 19, 1979.

The lease covers the geothermal resource property located within the Lower East Rift Geothermal Subzone of the Puna District, Island and State of Hawaii, situated on Tax Map Key No. 3rd/1-4-01:02 and commonly referred to as the Hawaii Geothermal Project-Abott (HGP-A) site.

On November 27, 1985, an Agreement was entered into between the Department of Planning and Economic Development, the University of Hawaii, the County of Hawaii, all of whom are referred to as IIJoint Ventures", and the Natural Energy Laboratory of Hawaii (NELH), wherein all rights, interests, liabilities, and responsibilities for the HGP-A well head generator and the surrounding site were transferred to NELH.

On September 15, 1995, NEIRA requested a geothermal well permit to set a temporary plug in the HGP-A well, pending a more permanent plug to be installed in Fiscal Year 1996. The permit was issued by DLNR on October 17, 1994.

The 1995 Legislature approved appropriations for $290,000 to permanently plug and abandon the HGP-A geothermal well. Accordingly, NELHA hereby requests a geothermal well abandonment permit to permanently plug and abandon the HGP-A well.

1. Introduction

WELLHGP-A RECOMMENDED PROCEDURE FOR

WELL PLUGGING AND ABANDONMENT

During November 28 through December 2, 1994, a temporary plugging of

well HGP-A in Puna, Hawaii, was conducted in order to reduce a potential casing

damage and deterioration hazard and to terminate the communication between the

surface facilities with the reservoir.

The partial plugging was achieved by placing a Baker inflatable packer at

the depth of 2,972 feet. A sand plug was placed between this depth and 2,959 feet.

Two cement plugs were displaced above the sand: the first one between 2,943 and

2,773 feet, and the second from 2,757 to 2,700 feet. The upper portion of the well

was saved to allow the re-installation of a seismic monitoring instrumentation

package (see figure 1).

At the end of the partial plugging operation, the well was filled with water

and it was observed that the water level dropped, possibly due to leakage in the

upper portion of the casing. The extent and the depth of the leaking zone(s) were

unknown; these appeared to be small, possibly due either to pinhole-size openings

in the casing, especially between 2,530 and 2,533 feet, where the 7 -inch casing was

perforated in 1979, or due to lack of seal in the threads of the buttress casing:

however, the well did not appear to lack integrity above the cement plugs_

1

(510) 527·9876 CABLE ADDRESS GEOTHERMEX TELEX 709152 STEAM UD FAX (510) 527-8164

Even under the temporary-plugged conditions as HGP-A is now, there are

potential risks, and consequently a responsibility and cost involved in monitoring

the well. Therefore, it was decided to consider an appropriate program and

consequent budget for permanent well plugging and abandonment procedures, but

the consideration of having to squeeze cement in the leaking zones had still to be

addressed before a definitive plan was issued. The plugging procedure would have

to be different if the well proved to leak excessively.

A two-step diagnostic test procedure was designed by GeothermEx in

October, 1995 in order to obtain more information about the nature of the leak

zone(s). The first step of the test, which involved injecting water under pressure

and observing the amount of fluid that the well could take under those conditions,

was conducted by the NELH during November 16, 1995. This part of the test was

specifically designed to investigate the extent of the leak(s). The second stage,

which would follow the first one at a later date, was to be conducted only if the

results obtained from the first stage showed a significant amount of leakage, and

was designed to detect the depth at which the leakage was occuring.

According to the proposed plan, if the loss of water in the well exceeded

the 5 GPM rate, some provisions would have to be made in the plugging and

abandonment program in order to squeeze cement in the leak zone(s).

The results of the first stage of the test showed that the well would not leak

more than 0.14 GPM at 150 psig wellhead pressure, thus confirming that the the

possibilities of obtaining good results with a cement squeeze during the

abandonment operations would be very marginal, and that it was not necessary to

2

SUITE 201



proceed with the second step of the diagnostic test. (see NELH's repon on the

results of the first step diagnostic test, included on the Appendix)_

The proposed well plugging and abandonment procedure for well HGP-A

involves the following steps:

• Mobilize a medium-scale rig, equipped with adequate capacity pumps and

drill rods to displace large-volume cement plugs (See specifications for the

optimum rig equipment shown on the Appendix).

• Re-enter the well to the actual top of the cement plug (2,700 feet)_ Place

cement and high viscosity mud plugs intercalated in the the upper 2,700 feet

that still remain open, in correspondence with selected depths, as described

in the step-by-step procedure, following the guidelines of the Geothermal

Resource Order No.3, issued by the U.S. Geological Survey (see figure 2).

• Cut-off the casing head and restore the ground to appropriate specifications

as dictated by the Department of Land and Natural Resources (D!\~R)_

The proposed plugging operation, which would not involve drilling the

cement plugs already in place inside casing or entering into contact with the

geothermal reservoir, has the advantage of reduced risk, and could be conducted

with a medium scale rig with the appropriate tubular tools, pumps and hoisting

capacity, and without requiring the installation of BOP equipment, since the well

already has a 270-foot cement plug above the inflatable packer located at 2.972

feet.

GeothermEx, Inc. (510) 527-9876


CABLE ADDRESS GEOTHERMEX TELEX 709152 STEAM UD FAX (510) 527·8164

Drilling through the cement plugs and the inflatable packer inside the

casing, where integrity and strength are unknown, would be difficult and risky.

The potential risks include:

• sidetracking out of the well with the drilling bit while drilling off the hard

cement; and

• exposing the upper portion of the well, where minor leaks have been

measured, to some degree of flow and pressure from the reservoir.

Furthermore, plugging the additional footage would require a difficult and

costly cementing operation, because the interval to be drilled out (a length of 1,025

feet) occurs within open and permeable formation. Additionally, the new plug

would not add much margin of safety to the present condition the well.

The following steps describe the recommended operation.

2. Recommended Procedure:

1. Prior to mobilizing a rig to the site, proceed to perform all the necessary

procurement of equipment and materials, and the contracting and

permitting procedures. The optimum rig specifications for conducting the

job are shown on the Appendix.

4




2. Mobilize the drilling rig. Nipple off the 6-inch lubricator and double

studded adaptor flange currently installed above the master valve (see figure

3). Connect the well to an appropriate water supply through its side valve.

3. Fill well with water. Run into the hole wlth open ended drill pipe and

displace a 300 ft cement plug (plug #1) above the top of the cement at

2,700 feet. Wait on cement 6 hours before tagging. Apply 6 tons weight on

the cement to test for strength.

4. Prepare a batch of high viscosity drilling mud and place mud above the top

of the cement plug.

5. Run into the hole with open ended drill pipe to a depth of ±2,260 feet and

set a second cement plug (plug #2) of approximately 200 feet, to cover the

zone at the level of the 9-5/8-inch casing shoe and the 7-inch D.V. collar

located at 2,163 feet.


of the cement plug.

7. Repeat step 3 at a depth of approximately 1,000 feet and set a third cement

plug (plug #3) to cover approximately 100 feet at the level of the 13-3/8-

inch casing shoe. Do not wait on cement to set.

9. Repeat again step 3 at a depth of approximately 400 feet and set a fourth

cement plug (plug #4) to cover approximately 100 feet at the level of the

20-inch casing shoe. Do not wait on cement to set.


of the cement plug.

11. Set a fifth cement plug (plug #5) to reach from 100 feet to the surface.

Wait on cement to set for 6-12 hours.

12. Dismantle drilling equipment. Cut off casing head and remove valve

equipment. Cut off casing stub 6 feet below ground level and weld a steel

cap on top of the casing stub. Remove concrete cellar and restore ground to

appropriate surface management agency's specifications.

During Mr. Kochy'a observation period, he noticed that as tho water level fell in the well, the rate Of water los~ also dec ined. This is expected since the water loss rate will de r ' ease proporciondtely with a decrease in static head pressure ab<'o 'e the leak.

In conclusion, I must assume that the leak(s) in the well e the cement plug is (are) very small. The leak rata is airtly slower than 5 gpm between 405-430 psi (3tatic pressure 5: pre~sures). Base~ on GeothermEx's experience, as stated in , test procedure, a leak rate of less than 5 gpm at a s~re above 50 psi will not afford a good cement sQueezQ.

I would fair to speculate that the leak ~i:l nee pose a pre Lem in perma~ently plugging and abandoning the WQll. The lQRk do! pose a potential problem under the presenc well co~diticns if ~e well is left unchecked. This is based on the t~ct that th.

RE: Request for Permit to Plug and Abandon HGP-A Well

Dear Mr. Wilson:

The Natural Energy Laboratory of Hawaii Authority (NELHA) is the successor interest to the Research Corporation of the University of Hawaii under the State of Hawaii Department of Land and Natural Resources Geothermal Resources Mining Lease No. S-4602 entered into between the State of Hawaii, Lessor, and the Research Corporation of the University of Hawaii on June 19, 1979.

The lease covers the geothermal resource property located within the Lower East Rift Geothermal Subzone of the Puna District, Island and State of Hawaii, situated on Tax Map Key No. 3rd/1-4-01:02 and commonly referred to as the Hawaii Geothermal Project-Abott (HGP-A) site.

On November 27, 1985, an Agreement was entered into between the Department of Planning and Economic Development, the University of Hawaii, the County of Hawaii, all of whom are referred to as "Joint Ventures", and the Natural Energy Laboratory of Hawaii (NElli), wherein all rights, interests, liabilities, and responsibilities for the HGP-A well head generator and the surrounding site were transferred to NElli.

On September 15, 1995, NELHA requested a geothermal well permit to set a temporary plug in the HGP-A well, pending a more permanent plug to be installed in Fiscal Year 1996. The permit was issued by DLNR on October 17, 1994.

The 1995 Legislature approved appropriations for $290,000 to permanently plug and abandon the HGP-A geothermal well. Accordingly, NELHA hereby requests a geothermal well abandonment permit to permanently plug and abandon the HGP-A well.


o The recommended procedure for the well plugging and abandonment is attached

hereto.

If you have any questions, please do not hesitate to call me or Mr. Jan War at (808) 329-7341.

1. Introduction

WELLHGP-A RECOMMENDED PROCEDURE FOR

WELL PLUGGING AND ABANDONMENT

During November 28 through December 2, 1994, a temporary plugging of

well HGP-A in Puna, Hawaii, was conducted in order to reduce a potential casing

damage and deterioration hazard and to terminate the communication between the

surface facilities with the reservoir.

The partial plugging was achieved by placing a Baker inflatable packer at

the depth of 2,972 feet. A sand plug was placed between this depth and 2,959 feet.

Two cement plugs were displaced above the sand: the first one between 2,943 and

2,773 feet, and the second from 2,757 to 2,700 feet. The upper portion of the well

was saved to allow the re-installation of a seismic monitoring instrumentation

package (see figure 1).

At the end of the partial plugging operation, the well was filled with water

and it was observed that the water level dropped, possibly due to leakage in the

upper portion of the casing. The extent and the depth of the leaking zone(s) were

unknown; these appeared to be small, possibly due either to pinhole-size openings

in the casing, especially between 2,530 and 2,533 feet, where the 7 -inch casing was

perforated in 1979, or due to lack of seal in the threads of the buttress casing;

however, the well did not appear to lack integrity above the cement plugs.

1

o SUITE 201



Even under the temporary-plugged conditions as HGP-A is now, there are

potential risks, and consequently a responsibility and cost involved in monitoring

the well. Therefore, it was decided to consider an appropriate program and

consequent budget for permanent well plugging and abandonment procedures, but

the consideration of having to squeeze cement in the leaking zones had still to be

addressed before a definitive plan was issued. The plugging procedure would have

to be different if the well proved to leak excessively.

A two-step diagnostic test procedure was designed by GeothermEx in

October, 1995 in order to obtain more information about the nature of the leak

zone(s). The first step of the test, which involved injecting water under pressure

and observing the amount of fluid that the well could take under those conditions,

was conducted by the NELH during November 16, 1995. This part of the test was

specifically designed to investigate the extent of the leak(s). The second stage,

which would follow the first one at a later date, was to be conducted only if the

results obtained from the first stage showed a significant amount of leakage, and

was designed to detect the depth at which the leakage was occuring.

According to the proposed plan, if the loss of water in the well exceeded

the 5 GPM rate, some provisions would have to be made in the plugging and

abandonment program in order to squeeze cement in the leak zone(s).

The results of the first stage of the test showed that the well would not leak

more than 0.14 GPM at 150 psig wellhead pressure, thus confirming that the the

possibilities of obtaining good results with a cement squeeze during the

abandonment operations would be very marginal, and that it was not necessary to

2

SUITE 201



proceed with the second step of the diagnostic test. (see NELH's report on the

results of the first step diagnostic test, included on the Appendix)_

The proposed well plugging and abandonment procedure for well HGP-A

involves the following steps:

• Mobilize a medium-scale rig, equipped with adequate capacity pumps and

drill rods to displace large-volume cement plugs (See specifications for the

optimum rig equipment shown on the Appendix).

• Re-enter the well to the actual top of the cement plug (2,700 feet). Place

cement and high viscosity mud plugs intercalated in the the upper 2,700 feet

that still remain open, in correspondence with selected depths, as described

in the step-by-step procedure, following the guidelines of the Geothermal

Resource Order No.3, issued by the U.S. Geological Survey (see figure 2).

• Cut-off the casing head and restore the ground to appropriate specifications

as dictated by the Department of Land and Natural Resources (DNLR)_

The proposed plugging operation, which would not involve drilling the

cement plugs already in place inside casing or entering into contact with the

geothermal reservoir, has the advantage of reduced risk, and could be conducted

with a medium scale rig with the appropriate tubular tools, pumps and hoisting

capacity, and without requiring the installation of BOP equipment, since the well

already has a 270-foot cement plug above the inflatable packer located at 2,972

feet.

SUITE 201

Drilling through the cement plugs and the inflatable packer inside the

casing, where integrity and strength are unknown, would be difficult and risky.

The potential risks include:

• sidetracking out of the well with the drilling bit while drilling off the hard

cement; and

• exposing the upper portion of the well, where minor leaks have been

measured, to some degree of flow and pressure from the reservoir.

Furthermore, plugging the additional footage would require a difficult and

costly cementing operation, because the interval to be drilled out (a length of 1,025

feet) occurs within open and permeable formation. Additionally, the new plug

would not add much margin of safety to the present condition the well.

The following steps describe the recommended operation.

2. Recommended Procedure:

1. Prior to mobilizing a rig to the site, proceed to perform all the necessary

procurement of equipment and materials, and the contracting and

permitting procedures. The optimum rig specifications for conducting the

job are shown on the Appendix.

4

SUITE 201



2. Mobilize the drilling rig. Nipple off the 6-inch lubricator and double

studded adaptor flange currently installed above the master valve (see figure

3). Connect the well to an appropriate water supply through its side valve.

3. Fill well with water. Run into the hole with open ended drill pipe and

displace a 300 ft cement plug (plug #1) above the top of the cement at

2,700 feet. Wait on cement 6 hours before tagging. Apply 6 tons weight on

the cement to test for strength.


of the cement plug.

5. Run into the hole with open ended drill pipe to a depth of ±2,260 feet and

set a second cement plug (plug #2) of approximately 200 feet, to cover the

zone at the level of the 9-5/8-inch casing shoe and the 7-inch D.V. collar

located at 2,163 feet.


of the cement plug.

7. Repeat step 3 at a depth of approximately 1,000 feet and set a third cement

plug (plug #3) to cover approximately 100 feet at the level of the 13-3/8-

inch casing shoe. Do not wait on cement to set.

9 _ Repeat again step 3 at a depth of approximately 400 feet and set a fourth

cement plug (plug #4) to cover approximately 100 feet at the level of the

20-inch casing shoe. Do not wait on cement to set.

10_ Prepare a batch of high viscosity drilling mud and place mud above the top

of the cement plug.

11. Set a fifth cement plug (plug #5) to reach from 100 feet to the surface.

Wait on cement to set for 6-12 hours.

12. Dismantle drilling equipment. Cut off casing head and remove valve

equipment. Cut off casing stub 6 feet below ground level and weld a steel

cap on top of the casing stub. Remove concrete cellar and restore ground to

appropriate surface management agency's specifications.

sm, ECT: Results of Diagnostic Test of HGP-A Well

On Thursday, November 16th, NELHA conducted a ~leak test- of th' HGP-A well usinQ' a hiqh pressure booster pump. water meter anc ! series of pressure gauges. The objective of the test was to de! mine how much water could be forced thrOIJoh a. suspected lec l (e) in the WQ11, at a specified water pressure of 125 psiq. We o11owed the recommended ~WQ11 Diagnostic Procodure" (10/9S) out ine~ by GeothermEx, Inc.'s senior engineer, Eduardo Granado!. In tG1QphortQ conversation with Mr. GranadoQ on 11/15, I di! uesed the type of eQUipment we had prepared for the test and th. 9~ooQdure we were planning to follow. I aloo indic~ted th~~ Or DOn Thomas and yourself would be on hand to witness and va. date the tQst.

In order to accomplish this task, a one horeepower (1 hp.) mu~ Lstage Jacuzzi booster oump (Model H4, 8.9 gpm @ 130 psi) was ~o: ~eted to ~ teet p~nel coneieting of two pre35ur~ 9au~e8, two CO! rol valves (globe), a pressure relief valve (@ 150 psi), a Ne; .,me water Io.eter (1/10 gal units) dnd vdt:iol.1~ 1" schedule 80 pvc fittings and pipe sectior.s. A by-pass circuit was plumbed int the test panel in order to dump excess water to prevent dead hei'" ing and over pressurizing the PUl':'IP. During the tests, a cor' cant pressure was applied co well with the main valve clOSed anc ~he 3" wing valve open. Four testa were conducted a: 125 psiq an, ~hrQQ tests WQre run at 150 psig. ~ac~ test was performed at te: ~inute time intervals.

After test #1, the pump was shut off and a nc:iceabl~ b~ck pr surG (rQvQrQ~ flow on water meter) was experienced. This n~y ha-" been caused by compressir..g a pocket of air tra.pped some wh·" Q in the well c:aeing. TC:Jts 2- i were 0':'1 conducted without: et· 'ping the pump. After the final test was conducted, ! did not no ce thifl back pressuring affect e.goin. A8 I.h~ tirr.e expired tor ea' te$~, the volume of water which had p~ssed through the water mc' r \-It\S measured and recorded. A new tesL. WC;iS 5tarted \-liehin 1-. minutQs ct the prior test with the purr~ still running. The te: preeeure \rae increased ofter t.eSL #4 by backing d.own on the cor rol valve directing water to the ground.

Before any of the prQssure tests were cor.ductsQ, a static prr sure test was run for 60 minutes with the well topped off to tht~ top of the 6" lubricator column. After one hour, the main va e was quiOkly closed and the displaced water volume measured wit a two liter gradua.ted cylinder. In preparation for this tet , the lubricator pipe and flange wers leak tested and found to e tight (ie. no water loss with main valve closed). With the rna valve open and the wall topped off with water. a noticeable let' was det~cted coming out of the main valve stem packino. DUI ng the static pressure lea~ test, the water from this leak war :ollscted and accounted for in the final calculations.

It should be noted that the too of t~e well is aocroximately 61: feet above rr.ean sea level. At this elevation and wit.h the wQ full of water, a static pressure of 280 ps~ is generated. Th; is the condition under which the sta~ic leak test was co; ~ctQd. Hare are the results of that test:

In looking through my not.es regarding the wsll logging <:.hat ct Kochy performed on t":'le water loss \'.Iithin HGP-A betwe6:~ ~/94 to Ol/l9/9S, I fou~c a calculation that I had made cased water level change of ~u in the l~bricator pipe (6-) in

:y minutes (30 min.). This works o~t tC a flew ratQ, unc!er Lc wall prassure conditicns, of approximately 0.04 gpm. This )nsistent wich the test result we experienced yesterday.

in ·rmation. I .:un assuming t.ho.t the 1eQk. in t.h~ 'I .... ell is below sea ie" -1.

During Mr. Kochy'a observation period, he noticed that es eh. water level fell in the well, the rate Of water los~ also dec ined. This is expected since the water loss rate will dec· ease proportionately with a decrease in static head pressure ab<-· ·e the leak.

In conclusion, I must assume that the leak(s) in the well abc e the cement plug is (are) very small. The leak rata i6 ce~ ainly slower than 5 gpm between 405-430 psi {3tatic pressure • I st pressures}. Base~ on GeothermEx's experience, as stated in thf ,test procedure, a leak rate of less than 5 gpm at a prf s~re above 50 psi will not afford a good cement 5QueeZQ.

I would fair to speculate that the leak wi:l not pose a pre Lern in perrna~ently plugging and abandoning the WQll. The 2Qak do( pose a potential problem under the present well conditions if ~e well is left unchecked. This is based on the f~ct that th~ WQ·. was observed to become pressurized if the "'Jater level is aL '/led to fall below the static head pressure whi ch prQv.nts ga~'·; from entering the well. The well should be constantly mOT :or&d and topped off with water beforA ; t turns ::hG corngr anc ~ecomes pressurized.

WELL HGP-A TEMPORARY PLUGGING OPERATION WORKOVER REPORT

A workover procedure was conducted in well HGP-A in Puna, Hawaii

during the period between 28 November and 1 December, 1994. The plugging

procedure was delineated in the document to DBEDT "Well HGP-A

Recommended Temporary Well Plugging Plan", issued by GeothermEx in

September. 1994 (see attachment 1).

Water Resources International (WRI, Honolulu, Hawaii) was the drilling

company selected to conduct the operation. WRI mobilized a self-propelled

Spencer-Harris drilling rig, equipped with 3,000 feet of drill pipe, and all the

ancillary tools required to conduct the job described in the workover plan.

Halliburton was contracted to provide the cementing services, and Baker Hughes

Inteq provided the inflatable packer and the services of a technician to assist in the

installation of the packer. GeothermEx, Inc. provided the services of a drilling

engineer to coordinate and supervise the operation at the wellsite. The workover

operation took place as planned between November 28 and December 1st, 1994.

The following was the sequence of operations conducted during this period:

11/28/94 At 7:00 am, bled off gases accumulated at the top portion of the

casing. Circulated bleed through caustic buffer solution. Dropped

pressure from 150 psi to 100 psi. Held safety meeting with all parties

involved. Pumped water into the well using WRI's mud pumps.

Pressure dropped to 0 psi within 1 hour. Discontinued pumping with

pumps, connected county water and continued quenching with - 76


11/29/94

o o


GPM of constant flow. Conducted BOP test at low pressure. Held

175 psi for 10 minutes. Tested OK.

Opened master valve, ran into the hole with open-ended 4" drillpipe

(equipped with TrW sub and foot valve) and set pipe to 3,008 feet.

Pumped 190 barrels of water with Halliburton pumps; closed BOP

against drill pipe and left well overnight with watchman on site. Left

county water (75 GPM) running during the night.

Opened BOP and started pulling pipe out of the hole. Eliminated

foot valve and TrW sub from string. Connected Baker inflatable plug

to one joint of drill pipe and filled joint with clear water. Put a grease

interface above water to avoid contamination of water during inflation

of packer. Ran into the hole to 2,971.9 ft. Filled up pipe by stages

and inflated packer with Halliburton pumps using the following

procedure: 500 psi (10 minutes); 1,000 psi (10 minutes); 1,500 psi (10

minutes); released pressure and activated packer check valve.

Unlatched from plug by setting 10,000 lbs weight on plug, pulled

10,000 Ibs and turned 1/4 tum to the right to unlock from "J" slot.

Pipe was successfully withdrawn. Picked up one stand of drill pipe;

mixed 400 Ibs qf black sand with 10 bbls of water and pumped sand

using Halliburton pump. Pulled out 15 stands and waited for sand to

settle above packer. Tagged top of sand at 2,959.4 ft. Prepared 35

if of cement slurry (Oass H, 40% Silica Flour, 0.75 CFR-3),

equivalent to 185 ft. of cement plug inside 7-inch casing. Pumped

slurry and displaced with 30 bbls of water; pulled out 10 stands of

drill pipe; pumped 65 bbls of water to clean out pipe; secured rig and

started waiting on cement. Left overnight guard at wellsite.

Observed water level inside well. Level was at the top of the flow

nipple. Ran into the hole and tagged top of cement at 2,775.4 ft. Set

pipe at 2,757.4 ft. and mixed 21.48 ff of sluny for next plug. Pumped

and displaced plug with 28 bbls of water. Picked up one stand of

drillpipe (60 ft.) to 2,697.4 ft. and circulated excess of cement; with 80

bbls of water. Good circulation returns observed at surface. Waited

on cement started at - 9:30 a.m.

Pulled out and laid down 10 stands of drillpipe. Secured rig and left

watchman overnight. Dismissed Baker engineer.

Observed water level inside well. Water was at the level of the 3-inch

valve (about 10 feet below rotary table). Level dropped because

driller opened 3-inch valve earlier in the morning. Tagged top of

cement at 2,700.15 ft; pumped 175 bbls of water with Halliburton

pump. Circulated well clean. Started pulling out of the hole laying

down drillpipe. Nippled off BOP; closed master valve; chained and

secured valve ~a~dles. No overnight watch left on weBsite.

Dismissed Halliburton. Stopped daily rate to WRI. Started

demobilization charges after 12/02/94.

RECOMMENDATIONS FOR FUTURE MONITORING OF THE WELL

The following recommendations were made verbally to the site caretaker

Mr. Robert Kochi, in order to follow the evolution of the well:

• Open master valve and fill up well with clear water to the rim of the valve.

Observe for a few minutes if presence of gas is detected. If so, close master

valve and report to GeothermEx.

• Leave I/2-inch valve open, or open for a few minutes every day in order to

release any pressure buildup in the well due to the expansion of the water.

Repeat this operation for a period of 2-3 weeks until temperature has

stabilized.

• If the water level drops inside of the well, monitor the water level,

measuring with a level meter on a daily basis, in order to establish the rest

leveL Continue monitoring for gas releases and report if gas is detected

coming from the welL

• If water level drops at a slow rate, two possible courses of action can be

taken: a) let the level drop until it reaches equilibrium with the external

phreatic level (measured at about 600 feet below ground level) or b)

continuously add county water through a I/2-inch pipe connected to the well,

with a check valve attached.

WELLHGP-A

RECOMMENDED TEMPORARY WELL PLUGGING PLAN

The procedure contemplated under this plan consists of performing a partial plugging of the well in order to reduce the potential casing damage hazard and to terminate the communication between the surface facilities with the reservoir. The upper portion will be saved to allow the use of the well for seismic monitoring or any other activity that does not require direct opening to the reservoir

(see figure 1).

The procedure assumes that the drilling rig will be assisted with Halliburton's cement pumps for the operations that require pumping

of cement and water.

1. Quench well with cold water. In the past, it has been possible to bleed off the gas pressure accumulated in the well to below 100 psi by bubbling the vented gas through a caustic soda solution, and initiate the quenching procedure with a portable centrifugal pump attached to the county water line. The well is quenched and enters into vacuum after 20 - 30 minutes of injecting a minimum water flow rate of 30 -40 GPM. Maintain well under constant water injection at all times during the

following operations.

2. Mobilize drilling rig, assemble BOP equipment (see figure 2). The master valve will be used as a "Complete Shut-Off" (CSO) device, therefore only a 7-inch bag-type BOP (Hydril) will be

required. After quenching the well, test master valve for full range of movement. Existing 2-inch wing valve should also be tested. Drilling rig must be equipped with a kelly cock valve. A tubing in-line plugging dart must be kept on the rig floor at all times and the corresponding seat must be included in the drill pipe.

3. Pressure-test BOP equipment. Test for 30 minutes; have State representative to witness the test.

4. Run into the hole for exploratory trip with 6-inch bit to 3,000 feet (depth where the well is to be plugged off); if an obstruction is detected at shallower depths, it may be necessary to work on the obstruction to open up a passage for the drill pipe. While doing this operation, the well is to be kept quenched by injecting cold water at a minimum rate of 20 GPM.

5. Pullout of the hole. Assemble Baker-type inflatable packer with hydraulic release tool. Attach to drill pipe using the sub provided by Baker. Re-enter the well with the inflatable packer and drill pipe to 3,000 feet (or maximum depth achieved on previous step).

6. At setting depth, pressurize the packer by stages of 300 psi each, allowing 1-2 minutes between each stage for the packer to stabilize. At 1,500 psi, set ± 1 ton weight from the string to test if packer is holding. Raise pressure to 2,500 psi to shear the screws on the release tool. Pressure will go down when the drill pipe has been released from the plug. Tag lightly the

2

o o SUITE 201


(510) 527·9876


plug with the weight of drill pipe (no more than 1 ton). Pull out of the hole.

7. Stop well quenching. Observe water level inside of the well. Disconnect release tool from the drill pipe and run into the hole with open ended drill pipe to 3,000 feet (or depth of the plug). Lightly tag on plug and raise drill pipe 15 feet. Pump a volume of approximately 300 lbs of 20-40 mesh frac sand. Displace sand with water and wait 10 - 15 minutes for sand to settle. Tag the top of the sand, repeat the operation if less than 10 feet of sand plug are tagged. Pull drill pipe 10 feet above sand plug and displace a 4 barrel cement plug (equivalent to ±100 feet of cement plug inside 7-inch, 26 lb/foot casing). Prepare cement slurry with class H cement and 2% calcium chloride. Displace cement with gel. Pullout 100 feet of drill pipe and wash the contaminated top of the plug. Displace excess cement.

8. Wait on cement 6 hours. Run into the well to tag top of cement. Set open ended drill pipe ± 10 feet above top of cement. Pump and displace two cement plugs in stages of 100 feet each as follows:

• Prepare a batch of high viscosity drilling mud and place mud above the top of the cement plug.

• Pump and displace volume of cement necessary to cover 100 feet of the well volume.

Dear Mr. Ahue: . .

The Natural Energy Laboratory of Hawaii Authority (NELHA) is the successor interest to the Research Corporation of the University of Hawaii under the State of Hawaii Department of Land and Natural Resources Geothermal Resources Mining Lease No. S-4602 entered into between the State of Hawaii, Lessor, and the Research Corporation of the University of Hawaii on June 19, 1979 .

. The lease covers the geothermal resource property located within the Lower East Rift Geothermal Subzone of the Puna District, Island and State of Hawaii, situated on Tax Map Key No. 3rdll-4-01:02 and commonly referred to as the Hawaii Geothermal Project-Abott (HGP-A) site.

On November 27, 1985, an Agreement was entered into between the Department of Planning and Economic Development, the University of Hawaii, the County of Hawaii all of whom are referred to as "Joint Ventures", and the Natural Energy Laboratory of Hawaii, wherein all rights, interest, liabilities and responsibilities for the HGP-A well head generator and the surrounding site were transferred to NELH.

NELHA's Board of Directors have determined that the HGP-A well should be temporarily plugged and secured. NELHA is therefore requesting permission to install a temporary plug and secure the HGP-A well within the next (30) days and to effect a more permanent plug during the Fiscal Year 1996.

RECOMMENDED TEMPORARY WELL PLUGGING PLAN

The procedure contemplated under this plan consists of performing a partial plugging of the well in order to reduce the potential casing damage hazard and to terminate the communication between the surface faci11ties with the reservoir. The upper portion will be saved to allow the use of the well for saisDrie monitoring or any

other activity that does not ~aquira direct opening to the ~servoir

(see figure 1).

The procedure assumes that the drilling r;g will be assisted with Hall i burton I $ cement pumps for the operations that require pumping

of cement and water.

1. Quench well with cold water. In the past, it has been possible to bleed off t.he ya~ pre~~ure ClCCUUlu1aLed in the we" to below

100 psi by bubbling till vantad gas through a caustic soda solution, and initiate the quenching procedure with a portable centrifugal pump attached to the county water line. The we'l is quenched and enters into vacuum after 20 4 30 .1nutas Qf injecting a minimum water flow ~&te of 10 ·40 GPM. Ma;ntain •• 11 under constant water injection at a11 times during the following operations.

2. Mobilize d~;11ing rig, assemble BOP equipment (se8 figure ~). The master valve will be used as a ·Complete Shut-Off" (CSO) device, therefore only a 7·inch bag-type BOP (Hydril) will be

required. After quench1ng the well, test master valve for full rang~ of ~ovement. Ex;~tin9 2·inch w;ng valva should al£o bQ

tested. Driliing rig must be equipped with a kelly cock va1ve. A tubing in-line plugging aart must be kept on the rig floor at all times ana the corresponding seat ;~J$t be included in the dl"i" p;pe.

3. ~ressure-test BOP equipment. Test for 30 minutes; have State representative to witness the test.

4. Run into the hole for exploratory trip with 6-inch bit to 3,000 feet (depth where the well is to be plugged off); if an obstruction is detected at shallower depths, it may be necessary to work on the obstruction to open up • passage for the drill pi~e. While doing this o~eration. the well is to be kept quenched by injecting cold water at a m1n;~ rate of 20 GPM.

5. Pullout of the hole. Assemble Baker-type inflatable packer with hYdraulic release teal. Attach to dr;11 pipe using the sub p~ovided by Baker. Re-enter the ~el1 witn the infl.table packer and dr111 p1pe to 3,000 fee't (or lIix'lmum depth achieved on

7. Stop well quenching. Observe water level inside of the well. D1sconneet release tool from the dr1'1 p1pe and run 1nto the hole with open endad dr;ll pipe to 3,000 feet (o~ depth of the plug). Lightly tag on plug and raise drill pipe 15 feet. Pump a volume of approximately 300 lbs of 20-40 mesh frae sand. Displace sand witb water and wait 10 • 15 nrinutes for sand to "ttle. Ta9 the top of the ,and, repeat the operation if leGG than 10 feet of sand plug are tagged. Pull drill pi~e 10 feet above sand plug and displace a 4 barrel cement plug (equivalent to :100 feet of cement plug inside 7-inch, 26 lb/foot casing). Prepare cement slurry with class H cement and 21 calc;um chloride. Displace cement with gel. Pullout 100 feet of drill pipe and wash the contaminated top of the plug. Displace excess cement.

8. Wa;t on cement 6 hours. Run into the well to tag top of cement. Set open ended drill pipe t 10 feet above top of cement. Pump and displace two cement plugs in stages of 100 feet each as tol1ows:

Thank you for your recent letter expressing the Department of ~Jiand Na~al Resources' (DLNR) interest in assuming title to the HGP-A well for use as a reservoir monitoring well. After reviewing the various options for the future disposition of the well, the Natural Energy Laboratory of Hawaii Authority (NELHA) has determined that the estimated costs to modify the well for reservoir monitoring purposes exceed current available funding.

Accordingly, NELHA will proceed with the plan to install a temporary cement plug in HGP-A as described in the application to DLNR for a Geothermal Well Modification Permit. The conclusion of the NELHA Board to proceed with the original plan will provide for securing of the well and utilization of its upper section for downhole monitoring. In light of this decision, NELHA is unable to transfer the HGP-A well to DLNR.

Please be advised that the County of Hawaii has expressed its interest in assuming responsibility and management of the entire Puna Research Center facility, including the HGP-A well. Preliminary discussions will be held to discuss the terms and conditions of the proposed transfer of the facility to the county and will include DLNR as the lessor of the underlying Geothermal Resource Mining Lease No. S-4602. Please be assured that DLNR engineers will be provided with continued access to the well for regulatory purposes until such time as the well is fully plugged and abandoned.

Recognizing that scheduling of required equipment and manpower is subject to issuance of the Geothermal Well Modification Permit, your assistance in expediting

Please be advised that the County of Hawaii has expressed its interest in assuming responsibility and management of the entire Puna Research Center facility, inclnding the HGP-A well. Preliminary discussions will be held to discuss the terms and conditions of the proposed transfer of the facility to the county and will include DLNR as the lessor of the underlying Geothermal Resource Mining Lease No. S-4602. Please be assured that DLNR engineers will be provided with continued access to the well for regulatory purposes until such time as the well is fully plugged and abandoned.

Recognizing that scheduling of required equipment and manpower is subject to issuance of the Geothermal Well Modification Permit, your assistance in expediting

We have received your letter requesting permission to temporarily plug and secure the HGP-A well, with permanent plug and abandon procedures to follow during Fiscal Year 1996.

The Planning Department agrees completely with your request, providing you receive approval of this procedure from the Department of Land and Natural Resources. We have reviewed the recommendations of GeothermEx Inc. regarding the HGP-A well and agree that this procedure is necessary and must be completed as soon as possible ••

It is our understanding that GeothermEx Inc. will be providing the overall supervision and oversight on both the temporary and the permanent plug and abandon procedures. We feel that this is a necessary a:nd critical step to insure that all procedures are followed and that any problems that arise during the operation(s) will be properly and safely handled.

We have recently become aware that the practice of removing the gas cap on the HGP-A well has been to vent it into a pile of rocks without any abatement for ~S. Although the well is to be plugged very soon, this practice of unabated venting must stop immediately. Any venting of accumulated gases in the well must follow the procedure of bubbling those gases through a solution of caustic soda sufficient to remove all noticeable (to the nose) concentrations of Hf. You will also need to check with the Department of Healt~ to ascertain if any permits are needed for these actions. At the minimum they should be aware of your activities.

----------_ •... _ ...... -

Energy Laboratory of Hawaii Authority (NELHA) met to discuss ~ture ~e ofCJ

the HGP-A geothermal well located at the Puna Research Center on {ije Big ~and. After discussing the condition of the well and maintenance requirements, the Board decided that the HGP-A well should be properly plugged and secured.

Recognizing current funding limitations, an interim plan was developed for temporary plugging of the well. The installation of a cement plug at a depth of 3,000 feet will provide for immediate securing of the well to mitigate potential risks. The recommended plan of action will secure the well in a safe manner while additional legislative funding is sought by NELHA to effect a more permanent plug during Fiscal Year 1996. The interim plan will also allow for continued use of the upper portion of the well for seismic research until the well is permanently plugged and abandoned.

The temporary well plugging operation will be initiated upon the following:

1) Approval of a Geothermal Well Modification Permit by the Department of Land and Natural Resources (DLNR). This permit is currently being sought by NELHA. (Separately, NELHA is requesting approval of the plan from the Hawaii County Planning Department.)

2) Approval and hiring of contractors through the University of Hawaii to provide the required specialized services. The cost for the plugging operation will be funded through an existing contract with the University's School of Ocean and Earth Science and Technology. The total estimated cost for the plugging operation is $190,000.

We are seeking the full cooperation and assistance from DLNR and the University to expedite their review and processing of the necessary documents to secure the well in a timely manner.

We understand that the Department of Business and Economic Development and Tourism (DBEDT) has recently asked the NELHA Board to consider the abandonment of the HGP-A well in Puna due to concerns regarding its long-term safety. We also understand that the Board has approved this proposal with the proviso that, if feasible, the HGP-A well be considered for conversion to a reservoir monitoring well.

We believe that the proximity of the HGP-A well to the geothermal field currently being developed below Puna Geothermal Venture would enable data collection and monitoring, which would provide important reservoir management information and be a valuable .addition to the Department of Land and Natural Resources' (DLNR) network of geothermal monitoring wells in the Puna District. On that basis, I would like to propose that NELHA consider transferring title of the HGP-A well to our department for use as a reservoir monitoring well conditioned on the following;

1. DBEDT/NELHA would provide the funding that would otherwise be required for a completed plugging and abandonment procedure;

2. DLNR will provide whatever additional costs that may be associated with the conversion of the HGP-A well to a monitoring well;

3. DLNR will take over management responsibilities for the abandonment/ conversion process;

Mr. Robert Kihune Page 2 SEP 13 199d

c o

4. DLNR engineers be provided with unconditional access to the well for purposes of monitoring the well until such time as it is fully plugged and abandoned.

We would appreciate any consideration that you can give to this proposal and would be happy to discuss the logistics of the transfer and conversion at your earliest convenience.

Should you have any questions, please contact Manabu Tagomori of the Division of Water and Land Development at 587-0230.

On the basis of information and advice which we recently obtained concerning the physical condition of the HGP-A geothermal well located at Pohoiki on the Island of Hawaii, we are concerned that any future use of the well may compromise its integrity. Therefore, we request that the NELHA Board consider taking timely action to inactivate the well permanently through plugging and abandonment.

We are prepared, through the Energy Division, to assist you in evaluating the condition of the HGP-A well and in determining its disposition.

· . o o 1.0 INTRODUCTION

The U.S. Environmental Protection Agency (EPA), Region IX, under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund Amendments and Reauthorization Act of 1986 (SARA) has tasked Bechtel Environmental, Inc. (BEl) to conduct a Preliminary Assessment (P A) of the Hawaii Geothermal Project (HGP-A) site located in Kapoho, Hawaii County, Hawaii.

The purpose of the PA is to review existing information on the site and its environs to assess the threat(s), if any, posed to public health, welfare, or the environment and to determine if further investigation under CERCLNSARA is warranted. The scope of the PA includes the review of information available from federal, state, and local agencies and performance of an onsite reconnaissance visit.

U sing these sources of existing information, the site is then evaluated using EPA's Hazard Ranking System (HRS) criteria to assess the relative threat associated with actual or potential releases of hazardous substances at the site. The HRS has been adopted by the EPA to help set priorities for further evaluation and eventual remedial action at hazardous waste sites. The HRS is the primary method of determining a site's eligibility for placement on the National Priorities List (NPL). The NPL identifies sites at which EPA may conduct remedial response actions. This report summarizes the findings of these preliminary investigative activities.

HGP-A was identified as a potential hazardous waste site and entered into the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) on November 23, 1992 (HID 984469544) (1). The site was entered into CERCLIS when mentioned in a petition submitted to the EPA concerning another potential hazardous waste site nearby (2).

1.1 Apparent Problem

The apparent problems at the site are as follows:

• The HGP-A site once operated as a geothermal power plant. Unlined settling ponds remain at the site where geothermal well fluids were disposed throughout the site's operation. (3) Sampling results of geothermal wastewater in on site ponds revealed the presence of arsenic, barium, chromium, copper, lead, mercury, and zinc (4,S).

2.0 SITE DESCRIPTION

2.1 Location

HGP-A is 3.S miles southeast of the town of Pahoa on Pahoa Pohoiki Road in Kapoho, Hawaii. The geographic coordinates of the site are 190 28' 31.S" N latitude and 1540 53' 43.0" W longitude (Pahoa South, Hawaii, 7.S-minute quadrangle) (6). The location of the site is shown in Figure 2-1.

, . o o 2.2 Site Description

The HGP-A site occupies approximately 4.1 acres in a sparsely populated area on the Island of Hawaii. HGP-A was once an operating geothermal power plant that has since been shut down and dismantled. The site consists of property owned by the State of Hawaii, Department of Land and Natural Resources (DLNR), and the Kapoho Land and Development Co. As a whole, the site is bordered to the south and west by a parking lot and Pahoa Pohoiki Road, to the north by property leased by Puna Geothermal Venture, and to the eas~ by papaya fields. (3)

Structures at the site currently include a visitors' center, two warehouses, a shut-in geothermal production well, the former power plant building, a caustic tank containing sodium hydroxide, one concrete-lined and one unlined sump, two concrete settling ponds, and a concrete detention pond. There are also three unlined settling ponds on site, which are separated from the remainder of the former geothermal plant by a fence. These ponds are the only portion of the site located on property currently owned by the Kapoho Land and Development Co. One of these ponds is backfilled with soil, while the other t}Vo remain empty. The concrete settling ponds and the detention pond appear to contain only residual rainwater. Both of the sumps are filled with concrete, metal, and other debris, but were apparently used for the containment of muds and well fluids during initial drilling activities on site. The two warehouses on site are currently in use and the visitors' center remains open to the public. One of the warehouses is used as a research facility for gathering data on local groundwater resources, while the other houses a small analytical lab. (3)

In addition to these structures, the remnants and foundations of a rock muffler~ cooling tower, incinerator and scrubber system, and supports for former aboveground piping are also present on site. Structures at the site, other than the visitors' center, are enclosed by a fence. The site remains unpaved, except for the visitors' center parking lot and the main entrance to the geothermal power plant. (3) The site layout is shown in Figure 2-2.

2.3 Operational History

The original owner of the site property was the Kapoho Land and Development Co. Prior to geothermal exploration and development on site, the property consisted of fallow land that was covered by lava flow from the 1955 eruption of the Kilauea volcano. The Kapoho Land and Development Co. uses land in the area to grow papaya. In 1972, the University of Hawaii proposed exploration and geophysical studies in Hawaii with funding from the National Science Foundation (NSF). Exploratory drilling of a 6,450-foot-deep geothermal well began on site in December 1975 and was completed in April 1976 by the University of Hawaii with funding from the NSF. In 1978, the DLNR purchased a portion of the site property from the Kapoho Land and Development Co. The State of Hawaii, Land Use Commission, permitted the site for development into a power plant, a research facility, and a visitors' information center in 1979. (3,7,8)

With funding from the U.S. Department of Energy, a geothermal power plant was built on site in 1981 to supply 3 megawatts (MW) of energy to the Hawaii Electric Light Company. The plant began power generation in March 1982. In 1985, the development group, which founded HOP-A, transferred all rights and interests concerning the site to the Natural Energy Laboratory of Hawaii. In 1989, the power plant shut down at the direction of the Hawaii County Planning Department because of increasing complaints of odor and noise related to operations on site. In 1990, most of the plant equipment was dismantled and removed. (3,7,8)

o o During its operation, the onsite geothermal well produced 100,000 pounds per hour of brine and steam. The geothermal fluid discharge from the well was directed to a centrifugal separator unit that separated the brine and steam. The brine phase flowed through aboveground piping to an atmospheric evaporation pond (detention pond) where some of the silica would precipitate and deposit on the concrete walls before the brine was routed to settling ponds on site. (3)

Steam from the separator flowed through a turbine-generator unit for power production and was eventually exhausted to a surface condenser. Condensed water was sent to a cooling tower where the majority of it was later used as makeup water for the surface condenser. Noncondensible gases were removed from the condenser and channeled to a treatment system. These gases were fIrst incinerated and then scrubbed with sodium hydroxide to reduce sulfur dioxide concentrations. Two treatment systems were used throughout the lifetime of the plant's operations. One of these systems channeled noncondensible gases through a column scrubber, whereas the second treatment system used a two-stage scubber. Both systems generated a sodium bisulfite solution as a waste product. Leftover condensate from the condenser, and the sodium bisulflte solution from the treatment system, were eventually discharged to the unlined settling ponds on site. (3)

The rock muffler consists of a concrete base and an upright, open-top steel tank. When steam could not be directed to the turbine for reasons such as a high vibration in the turbine or a leak in the pipeline, this was referred to as an upset condition. Under these circumstances, steam would be diverted from the separator to the rock muffler. The rock muffler provided a means of abating the hydrogen sulflde present in geothermal steam by enabling the operators to add sodium hydroxide to the tank. Reduced concentrations of hydrogen sulfide and other noncondensible gases were then emitted to the atmosphere. (3)

The Hawaii Department of Health (HOOH) currently monitors for hydrogen sulfide concentrations in ambient air at the site. The HOOH conducts this monitoring as part of its .oversight of operations at Puna Geothermal Venture, an operating geothermal-powered electric plant adjacent to the site. (3)

The onsite Puna Research Center employs two people who gather information and analytical data on groundwater resources in the area. This research is conductetl to assess the impact that geothermal activity may have on local groundwater resources. Research at the HGP-A site involves sampling and monitoring groundwater wells at the Puna Geothermal Venture plant. Groundwater levels are measured and samples are analyzed for salinity and temperature. (3)

In April 1989 and March 1990, sampling was conducted at the HGP-A site by the University of Hawaii to characterize the chemical composition of geothermal wastewater in unlined, onsite settling ponds. Sample analyses indicated the presence of arsenic, barium, copper, lead, chromium, mercury, and zinc at concentrations up to 0.04 milligrams per liter (mg/l), 3.7 mg/l, 0.16 mg/l, 0.76 mg/l, 0.06 mg/l, 0.02 mg/l, and 0.385 mg/l, respectively. (4,5) One of the three unlined settling ponds on site was backfIlled with soil following the April 1989 sampling and analysis event (4).

The only hazardous substance currently stored on site appears to be an unknown quantity of sodium hydroxide in an aboveground tank. Information about the capacity of the tank was not available at the time of the PA. (3)

o o 2.4 Regulatory Involvement

2.4.1 State of Hawaii, Department of Land and Natural Resources. The geothermal research facility currently operates under Geothermal Resources Mining Lease No. S-4602 issued by the State of Hawaii, Departtnent of Land and Natural Resources. The permit is valid through June 18, 2014. (7)

2.4.2 State of Hawaii, Department of Business and Economic Development, Land Use Commission. Special Permit No. SP78-307 from the State of Hawaii, Department of Business and Economic Development, Land Use Commission, was issued on February 7, 1979, and enforced by the County of Hawaii, Planning Department. This permit allowed the development of the HGP-A site into a geothermal power generation plant, a research facility, and a visitor information center. Although the permit was issued without a date of expiration, the Land Use Commission advised the Natural Energy Laboratory of Hawaii in December 1989 to shut down the power plant because of increasing complaints about odor and noise. Operations at the HGP-A geothermal power plant ceased in 1989 as a result. (7)

2.4.3 County of Hawaii, Planning Department. The County of Hawaii, Planning Departtnent, enforced Special Permit No. SP78-307 issued by the State of Hawaii, Department of Business and Economic Development, Land Use Commission (7).

3.0 HAZARD RANKING SYSTEM FACTORS

3.1 Sources of Contamination

Potential sources of contamination at the HGP-A site include:

• Two sumps that remain at the site adjacent to the shut-in production well. One of these sumps was lined with concrete, the other was unlined. Both were apparently used for containment of well fluids and muds during drilling activities.

• A concrete detention pond that received geothermal brine flowing from the brine/steam centrifugal separator unit. Silica present in the geothermal fluid would precipitate and deposit on the detention pond walls.

• Two concrete settling ponds that served as additional containment for the geothermal brine before the brine was transferred to unlined settling ponds on site.

• Three unlined settling ponds where geothermal brine, steam condensate, and a sodium bisulfite solution from the scrubbers were disposed. Three of these ponds exist at the site, one of which has since been backfilled. Sample analyses of wastewater from one of the ponds indicated the presence of metals.

• An unknown quantity of sodium hydroxide stored in an aboveground tank.

o o 3.2 Groundwater Pathway

3.2.1 Hydrogeological Setting. The site is within the Lower East Rift Zone of the Kilauea Volcano on the Island of Hawaii. This area is characterized by intrusive and extrusive basalt flows extending from the ground surface to thousands of feet below. (9) A large portion of the surface of Kilauea is covered by deposits of ash that range in thickness from less than an inch to several feet. Underlying the ash are the Puna and Hilina volcanic series, the two volcanic rock units of the Kilauea volcano. The overlying Puna volcanic series is characterized by basalts that thicken toward the summit to a maximum thickness of 490 feet in the wall of the caldera. (10) Along the rift zone, the Puna volcanic series contains closely-spaced, near-vertical dikes and fractures (9). The Puna volcanic series is separated by the underlying Hilina volcanic series by a layer of Pahala ash 10 feet to 40 feet thick. The Hilina volcanic series is more than 1,000 feet thick and consists of basalts and thin vitric tuff beds. (10)

On the Island of Hawaii, virtually all groundwater is derived from rainfall percolation into the highly permeable volcanic rocks. Despite rapid groundwater recharge, potable water is not recovered from 87 percent of the total area of the island because of the great depth to the zones of saturation. However,. large quantities of groundwater are stored between volcanic dikes, hundreds to thousands of feet above sea level. Groundwater under the site flows towards the southeast, where it discharges at the coast into the Pacific Ocean. (11)

Groundwater monitoring wells in the region of the HGP-A site indicate that the depth to groundwater at the site is approximately 600 feet below ground surface (bgs) in shallow basal or dike-confmed groundwater. (12)

3.2.2 Groundwater Targets. Three active municipal drinking water wells are within 4 miles of the site, with the nearest well being more than 3 miles away. These wells are operated by the County of Hawaii, Department of Water Supply, and contribute drinking water to a single drinking water system that serves a population of approximately 2,445 people. (13,14)

3.2.3 Groundwater Pathway Conclusion. Groundwater beneath the site occurs at approximately 600 feet bgs (9,12). Three drinking water wells are within 4 miles of the site, and they contribute to a single drinking water system that serves approximately 2,445 people. The nearest drinking water well is more than 3 miles from the site. (13,14)

3.3 Surface Water Pathway

The nearest surface water body is the Pacific Ocean, approximately 3 miles southwest of the site. Surface water runoff from the site appears to flow southwesterly towards the main gate and Pahoa Pohoiki Road. (3,6)

3.4 Soli Exposure and Air Pathway .

Other than the visitors center, the HGP-A site is fenced and inaccessible to the public. With the exception of the roadway at the main entrance to the site and the visitors center parking lot, the grounds are unpaved. Two full-time eqlployees are on site, but there are no residences, schools, or daycare centers on or within 200 feet of the site. The original geothermal power production operations have ceased and the geothermal well on site has been shut in. (3)

o o 4.0 EMERGENCY RESPONSE CONSIDERATIONS

The National Contingency Plan [40 CFR 300.415 (b) (2)] authorizes the EPA to consider emergency response actions at those sites that pose an imminent threat to human health or the environment. For the following reasons, a referral to Region IX's Emergency Response Section does not appear to be necessary:

• The site is fenced, not open to the public, and a geothermal power production plant no longer operates at the site.

5.0 SUMMARY

The Hawaii Geothermal Project is a non-operational geothermal power production plant 3.5 miles southeast of the town of Pahoa on Pahoa Pohoiki Road in Kapoho, Hawaii. The site occupies approximately 4.1 acres in a sparsely populated area on the Island of Hawaii. The Hawaii Geothermal Project site currently consists of the following: a visitors' center, two warehouses, a shut-in production well, the former power plant building, a caustic tank, one lined and one unlined sump, two unlined settling ponds and one unlined settling pond that has been backfilled, two concrete-lined settling ponds, and a concrete detention pond. The remnants and foundations of a rock muffler, a cooling tower, an incinerator and scrubber system, and supports for former aboveground piping also exist at the site. Structures on site, other than the visitors' center, are enclosed by a fence. With the exception of the main entrance and the visitors center parking lot, the site remains unpaved.

In 1972, geothermal exploration conducted by the University of Hawaii began with funding from the National Science Foundation. The University of Hawaii's Hawaii Geothermal Project initiated geothermal exploration on site with the drilling of a 6,450-foot-deep geothermal production well that was completed in 1976. With funding from the U.S. Department of Energy, a geothermal power plant was constructed on site in 1981, and in 1982, the plant began supplying 3 megawatts of energy to the Hawaii Electric Light Company. Under the direction of the Hawaii County Planning Commission, the power plant was shut down in 1989 as a. result of increasing complaints of odor and noise related to site operations. In 1990, the majority of equipment on site was dismantled and removed.

During its operation, geothermal fluids from the production well discharged to a centrifugal separator unit. Steam from the separator was directed through a turbine-generator unit for power production, whereas the brine flowed to an onsite detention pond. Steam from the turbine exhausted to a surface condenser and the condensate was then pumped to a cooling tower. Noncondensible gases within the condenser were routed to an incinerator and scrubber treatment system. The brine, geothermal steam condensate, and sodium bisulfite solution generated in the treatment system were eventually disposed of in unlined settling ponds on site. In April 1989 and March 1990, sampling was conducted on site by the University of Hawaii to characterize the chemical composition of geothermal wastewater in the unlined settling ponds. Sample analyses indicated the presence of arsenic, barium, copper, lead, chromium, mercury, and zinc. One of these ponds was backfIlled with soil following the April 1989 sampling and analysis events.

Two sumps adjacent to the wellhead were apparently used for the containment of muds and geothermal fluids during well-drilling activities. These sumps are currently filled with concrete,

o o metal, and other debris. The concrete detention pond and lined settling ponds are empty except for rainwater.

The State of Hawaii, Department of Business and Economic Development, Land Use Commission permitted the site for development into a geothermal power generation plant, a research facility, and a visitors' information center in February 1979. The permit was enforced by the County of Hawaii, Planning Department that directed the power plant in 1989 to permanently shut down because of increasing complaints of odor and noise related to its operation.

Groundwater occurs approximately 600 feet below ground surface at the site. Soils beneath the site include volcanic ash and basalts. Three drinking water wells are within 4 miles of the site, and they contribute to a single drinking water system that ·serves approximately 2,445 people. The nearest drinking water well is more than 3 miles from the site.

The nearest surface water body is the Pacific Ocean, approximately 3 miles southwest of the site.

With the exception of the visitors' center, the site is fenced and not open to the public. The only portion of the site that is paved is the visitors' center parking lot and the entrance at the main gate to the former geothermal power plant. Two full-time employees are on site, but no residences, schools, or daycare centers are on site or within 200 feet.

The pertinent Hazard Ranking System factors associated with the site are:

• Groundwater occurs approximately 600 feet below ground surface and there are only three drinking water wells, which serve approximately 2,445 people, within 4 miles of the site.

• The nearest surface water body is approximately 3 miles from the site.

• No residences, schools, or daycare centers are on or within 200 feet of the site ..

• The former geothermal power plant and associated ponds are fenced and not open to the public.

DISCUSSION:

The Hawaiian hawk, Hawaiian owl, and Hawaiian bat, are federally endangered birds that

inhabit regions near the Puna Geothermal Venture site. Mr. Bockman mentioned that the

Hawaiian hawk is known to nest in areas around the site. Other federally endangered birds that

could potentially be found in areas surrounding the site are the black-necked stilt and the N4I~e.. P

Hawaiian goose (NeNe). Two ocean birds, the newells shearwater and the dark-rumped~trel,

might 'stsu"ltAcl frequent the Puna District on overflights. These birds are also listed as federally

endangered species.

Mr. Bockman noted that to the best of his knowledge, populations for the Hawaiian hawk, owl,

and bat, have not been adversely affected by activities at the Puna Geothermal Venture site. He

did mention, however, that the Hawaiian bat might have suffered detrimentally from the original

land clearing that took place for the project. Mr. Bockman believes that hazardous constituents in

onsite surface impoundments and the releases of hydrogen sulfide to air were less likely to impact

wildlife in the area then the effects of birds colliding at night with drill rigs and smoke stacks.

SITE: Hawaii Geothermal Project

EPA ID: HID 984469544

A site reconnaissance was conducted at the Hawaii Geothermal Project (HGP-A) site on June 9, 1993. The weather was sunny and the temperature was approximately 85°F. The Bechtel team, Deborah Tharp and Gary Yao, conducted the site reconnaissance with Clare Hachmuth and Dr. Donald Thomas at 3 p.m. at Hawaii Geothermal Project to gather information on the site location and size, history, processes used, and any hazardous waste generated, treated, stored, or disposed of on site. The Bechtel team was provided with a packet of information prepared in response to Bechtel's letter dated May 13, 1993. The reconnaissance included a site tour during which photographs were taken.

The following information was obtained during the site reconnaissance:

A brief history of the site was given by the site representatives. The original owner of the site property was the Kapoho Land and Development Co. Prior to geothermal exploration and development on site, the property consisted of fallow land that was covered by lava flow from the 1955 eruption of the Kilauea volcano. The Kapoho Land and Development Co. uses land in the area for growing papaya. In 1972, the University of Hawaii proposed exploration and geophysical studies in Hawaii with funding from the National Science Foundation (NSF). Exploratory drilling, funded by the NSF, occurred on site between December 1975 and April 1976. The fIrst production test of the newly drilled 6,450-foot geothermal well took place in July 1976. The Department of Energy (DOE) received a proposal in 1979 for funding of a 3 megawatt (MW) demonstration geothermal power plant on site. The construction of the power plant was completed in 1981, and in March 1982 the plant began to operate commercially, supplying energy to the Hawaii Electric Light Company. The plant shut down in 1989, and most of the equipment was dismantled and sold in 1990.

The HGP-A site occupies approximately 4.1 acres in a sparsely populated area on the Island of Hawaii. HGP-A was once an operating geothennal power plant that has since been shut down and dismantled. The site is bordered to the south and west by a parking lot and Pahoa Pohoiki Road, to the north by property leased by Puna Geothermal Venture, and to the east by papaya fIelds.

("'J .0 SITE RECONNAISSANCE INTERVIEW AND OBSERVATIONS REPORT (Cont'd)


The primary structures on site currently include a visitors' center, two warehouses, a closed (shutin) production well, the former power plant, a caustic tank containing sodium hydroxide, a concrete-lined and an unlined sump, two concrete settling ponds, and a concrete detention pond. There are also three unlined settling ponds on site, which are separated from the remainder of the former geothermal power plant by a fence. Using conservative visual estimates, the ponds were estimated to be about 150 feet long by 30 feet wide by 15 feet deep. These ponds are on property still owned by the Kapoho Land and Development Co. One of the ponds has been backfilled with soil, while the other two remain empty. The two' concrete settling ponds apparently cover 800 square feet, while the detention pond was estimated to be 50 feet long by 20 feet wide by 3 feet deep. Both the concrete settling ponds and the detention pond appear to contain only residual rainwater. The two sumps are filled with concrete, metal, and other debris, but were apparently used for the containment of muds and well fluids during initial drilling activities on site. Each of the two sumps is estimated to be 25 feet long by 10 feet wide.

The two warehouses on site are currently used for ongoing research, and the visitors' center is still open to the public. One of the warehouses is used as a research facility for the study of local groundwater resources, while the other houses a small analytical lab. In addition to these structures, the remnants and foundations of a rock muffler, a cooling tower, an incinerator and scrubber system, and supports for former aboveground piping are also present on site. Structures on site, other than the visitors center, are enclosed by a fence. The site remains unpaved, except for the entrance at the main gate and the visitors' center parking lot.

The geothermal well at the HGP-A site produced 100,000 pounds per hour of brine and steam. The geothermal fluid discharge from the well was directed to a centrifugal separator unit that separated the brine and steam. The brine phase was first piped to an atmospheric evaporation tank (detention pond), where some of the silica would precipitate before this brine was routed to the settling ponds. Steam from the well flowed through a turbine generator unit for power production and was eventually exhausted to a surface condenser, known as a shell and tube condenser. Condensed water was sent to a cooling tower, where the majority of it was later used as makeup cooling water for the surface condenser. Noncondensible gases, which were removed from the surface condenser, were channeled to a treatment system. These gases were first incinerated and then scrubbed with sodium hydroxide to reduce sulfur dioxide concentrations. Two treatment systems were used throughout the lifetime of the plant's operations. One of these systems channeled noncondensible gases through a column scrubber, whereas the second treatment system used a two-stage scrubber. Both systems generated a sodium bisulfite solution as a waste product. Leftover condensate from the condenser and the sodium bilsulfite solution from the treatment system were eventually discharged to the unlined settling ponds on site.

The rock muffler consists of a concrete base with an upright, open-top steel tank. When steam could not be directed to the turbine for reasons such as a high vibration in the turbine or a leak in the pipeline, this was referred to as an upset condition. Under these circumstances, steam would be diverted from the separator to the rock muffler. The rock muffler provided a means of abating the hydrogen sulfide present in geothermal steam by enabling the operators to add sodium hydroxide to the tank. Reduced concentrations of hydrogen sulfide and other noncondensible gases were then emitted to the atmosphere.

o o SITE RECONNAISSANCE INTERVIEW AND OBSERVATIONS REPORT (Cont'd)


The Hawaii Department of Health (HOOH) currently uses the site to monitor for hydrogen sulfide concentrations in ambient air. The HOOH conducts this monitoring in its oversight of operations at Puna Geothennal Venture, an operating geothermal-powered electric plant adjacent to the site. The Puna Research Center on site employees two people who gather information and analytical data on groundwater resources in the area, and on the impact that geothermal activity may have on these resources. Research at the HGP-A site involves sampling and monitoring groundwater wells at the Puna Geothennal Venture plant. Groundwater levels are measured and samples are analyzed for salinity and temperature in the analytical lab on site.

Interagency Agreement No. DE-AI05-930R22089 Performing Agency: u.s. Department of· Interior

Geological Survey

I. PURPOSE

o

The U.S. Department of Energy (DOE) has a need for the technical support and assistance of the U~S~ Department of Interior, Geological Survey, in discerning salient geologic information in relation to 'environmental impacts from the proposed development of geothermal power in the State of Hawaii. This assistance is requested pursuant to the 1992 Memorandum of Understanding regarding the preparation of an Environmental Impact Statement for the Hawaii Geothermal Project. The tasks described in the Scope of Work shall focus on proposed sites for the Hawaii Geothermal Project (HGP), affected portions of the Puna District surrounding the HGP on the Island of Hawaii, and the proposed corridors for transmission lines (including conversion stations) in the State of Hawaii. DOE will use this information in the preparation of an Environmental Impact Statement (EIS) for the proposed HGP. DOE expects USGS experts to provide technically reliable and most recent geoscience information about the areas potentially affected by the proposed HGP so that accurate analyses of environmental impacts can be performed by DOE or its designated representative. Because USGS input to the EIS must be accessible for public scrutiny, all final products described below will be released as USGS Open-File Reports or in other publications prior to completion of the draft HGP EIS (currently scheduled for the end of the CY 1993).

II. SCOPE OF WORK

Task 1: Literature Search and Technical Review

Description:

The USGS shall search and review its research and technical library (both published and unpublished sources) to identify information for the following topics. (1) volcanic emissions in relation to ambient air concentrat; ons ; n proxi mi ty to the HGP, (2) groundwater and geothermal hydrology of Kilauea, (3) volcanology and ground deformation with a primary focus on potential hazard impacts for the HGP, (4) seismiCity of the Island of Hawaii and adjacent ocean areas, (5) marine geology of the Hawaiian Islands, with special focus on natural marine hazards, including submarine slides and turbidity currents. USGS shall provide DOE with a selected annotated bibliography, describing the most important references that are reviewable within the allocated working time, and indicating their quality and relevance to environmental issues raised by the HGP. Annotated bibliographies for each of the five topics shall be accompanied by two copies of all referenced USGS publications that are still in print.

o o. -3- DE-AI05-930R22089

Unpublished cited information shall be described in sufficient detail to allow DOE to evaluate its usefulness for the EIS, and where appropriate, will be included in publications prepared as products of Task 3. Subjects requiring additional effort by USGS beyond preparation of annotated bibliographies are discussed further under Task 3, below.

Justification:

The information to be provided by Task 1 is required for DOE to identify those technical areas that are currently well defined and those that require additional technical studies by USGS (or others) to support impact analyses as required for the EIS (see Task 3, below).

Level of Effort:

0.5 Full Time Equivalent (FTE); approximately 0.1 FTE per Task 1 topic, as listed above.

Task 2: Geothermal Fluid Characterization

Description:

There are approximately tem completed geothermal test wells and four Scientific Observation Holes (SOH) in the Puna District of Hawaii, which is the general location of the HGP. The USGS shall identify for DOE those wells that have been adequately characterized with respect to chemical constituents in geothermal fluids, those that may require additional chemical characterization, and those that may be accessible for sample collection and analysis. The HGP impacts analysis would be strengthened if geothermal fluids were characterized for as many different areas in the Puna District as possible, including those areas with thermal springs. Sample collection from geothermal test wells shall be performed in such a manner as to capture all condensible and non-condensible gases, and all liquids. DOE and USGS shall consult on sampling protocols prior to initiation of field work.

USGS laboratory staff shall fully characterize the constituents of each fluid sample. The percentage of water in the liquid and steam phases also shall be estimated. The EPA priority pollutant list (Code of Federal Regulations) shall be considered in selecting species whose stoichiometric quantities must be determined. Based on its own expertise and judgment, the USGS also shall define additional chemical species to be analyzed. The USGS shall provide DOE with a report which provides chemical characterization of each well sampled, including liquid and gaseous phases, and the percent steam yield.

'.C. o -4- DE-AI05-930R220S9

Justification:

Knowledge of the chemical characteristics of fluids from geothermal wells is required for the EIS to evaluate the potential environmental impacts of routine well drilling, controlled well venting, production and reinjection of geothermal fl uids, and surface impoundments. Such characterization also i.s.n~cessary to analyze the environmental impacts of (1) accidental subsurfac'e casing rupture on ground water resourceS" arid (2) accidental uncontrolled well venting on water resources and air quality.

level of Effort:

The level of effort for this sampling depends on the accessibility of geothermal wells in the Puna District; a critical initial step will be relief fr,om the court order prohibiting any federally funded studies of material s from the HGP. Some well s are dry; otheers are heavily instrumented and unavailable for sample collection; and still others (4 to 6 near the HGP-A well which has already been characterized) are shut-in while waiting to go on-line as production wells. Ideally, all the shut-in production wells could be sampled within a several-day period, assuming the court and .the developers allow such, sampling. Field sampling, chemical analYSiS, interpretation, and report writing for all the shut-in production wells should require a total of apprOXimately 0.4 FTE. Sample collection time-requirements for· other wells (if feasible) is unknown at this time.

Task 3: USGS Technical Analyses

The following tasks are arranged in order of priority. Task 3A and 38 have the highest priority. These two tasks will provide information necessary for analysis of impacts from construction, development, and operation of HGP. Task 3C-3F are roughly equivalent in priority. The latter tasks are related to accident-driven impacts during the operation of HGP. DOE will provide the USGS with summary plans for HGP transmission-line routes and locations of near-shore facilities prior to initiation of work on Task 3.

Task 3A: Volcanic Gas Emissions

Description:

Data are required to characterize background emissions from Kilauea's summit and its East Rift Zone, against which the effects of HGP emissions can be compared. Major data types will include results of direct measurement of Kilauea emissions during eruptive and repose periods,

o -5- DE-AIOS-930R22089

and also indirect samples using precipitation collections. Background air concentration data surrounding HGP for the Puna District (if available) would be useful to compare with ambient air measurements near East Rift volcanogenic sources.

Justification:

Background ambient air measurements for the volcanogenic component are needed for the EIS to help determine the impact from routine construction and operations emissions, and the impact from accidental uncontrolled well venting. This information is also important in establishing air quality standards and monitoring requirements to be met under the terms of State, County, and local air quality permits.

Level of Effort:

O.3HE

Task 38: Characterization of and Impact on Ground Water Resources

Description:

The major questions to be resolved are whether or not existing or planned potable or industrial ground-water wells near HGP could be contaminated during normal or upset conditions, and where a suitable water supply can be obtained to construct and operate HGP, including cool ing water for power plants and AC to DC conversion facilities. Large quantities of water will be required to quench wells if accidental blowouts occur. The scope of work for this task includes characterization both of the quality and quantity of ground-water resources in the general vicinity of the HGP and possible impacts of -:geothermal development on these resources. Available groundwater wells, cold springs, and thermal springs should be inventoried and sampled. If necessary, the USGS should consult with the County of Hawaii to complete this water resource evaluation and to bring it up-to-date. Locations of nearby catchment water systems would be useful information.

Justification:

Background ground water data are required for the EIS to determine the impacts from construction, development, and operation of HGP. A principal objective is to determine whether the ground-water use category will change as a result of HGP.

Level of Effort:

0.4 HE

,.

·0 . o -6- DE-AI05-930R22089

Task 3C: Volcanic Activity and Deformation Hazard Analysis

Description:

Volcanic and deformation hazards will be analyzed on the basis of distribution/age maps of Holocene and historic lava flows and tephra eruptions, and of geologically and geodetically determined uplift, subsidence, and extension, for the East Rift Zone of Kilauea (geothermal power plants) and along the flanks of Mauna loa and Mauna Kea (transmission line routes and AC-DC conversion stations). To the degree available data permit, the report shall estimate the probabilities and magnitudes of occurrence of these events over the 50-year operating life of HGP.

Justification:

It is assumed that volcanic activity, uplift, and subsidence could cause: . (1) simultaneous multiple well-head failures resulting in uncontrolled venting, (2) toppling of transmission line poles along the two proposed transmission line routes, (3) turbidity current damage to an undersea transmission line, and (4) seismic sea wave (tsunami) damage to shoreline installation (AC-DC conversion stations and near-shore transmission lines)". HGP production facilities will also require deformationmonitoring instrumentation to evaluate local production-induced subsidence and uplift resulting from withdrawal and injection of geothermal fluids. Knowledge of volcanic activity and ground deformation are required to support analysis in the EIS of potential impacts on HGP facilities.

level of Effort:

0.5 FTE

Task 3D: Seismic Hazard Analysis

Description:

The USGS shall perform a sei smi c hazard ana lys is for the East Ri ft of Kilauea. Historical activity will be summarized in graphic plots. Peak ground accelerations and their uncertainties shall_be estimated for time intervals ranging from 50 to 10,000 years.

The potent i a 1 for ground mot ion magn i fi cat ion, 1 i que fact ion, surface rupture, and earthquake-induced landslides along the East Rift Zone and along the proposed transmission line routes also shall be evaluated.

o o. -7- DE-AI05-930R22089

Justification:

It is assumed that strong-motion earthquakes can cause: (1) simultaneous multiple well-head failures resulting in uncontrolled venting, (2) toppling of transmission line poles along the two proposed transmission line routes, and (3) coastal landslides, tsunami, and underwater turbidity currents (see Task 3E). If well-heads are designed to resist ground motions up to a given peak ground acceleration, one could ascertain the probability of uncontrolled venting of one or more wells. Knowledge of seismic hazards is required to support analysiS in the EIS of potential impacts on HGP facilities.

level of Effort:

0.7 FTE

Task 3E: Natural Marine Hazards, Including Undersea Slides and Turbidity Currents

Description:

The potential for natural marine hazards, especially seismic sea waves (tsunami), rock and sand slides, and turbidity currents to impact undersea cables and conversion stations near the shoreline shall be considered. Historical occurrences· of the phenomena shall be cited. Information relative to magnitude-recurrence interval shall be provided if obtainable.

Justification:

Tsunami , coastal 1 ands 1 ides, or underwater turbidity currents caul d damage shoreline installation (AC-DC conversion stations and near-shore transmission lines) and undersea transmission lines. A shut-down of conversion facilities or damage to a transmission line would cause widespread power failures, having a devastating effect on the economy of Hawaii if alternative sources of energy become unavailable. Furthermore, geothermal wells would have to shut down to avoid damage to HGP. These events would lead to unscheduled venting of production wells during the required shut-down period. Knowledge of natural marine hazards is required to support analysiS in the EIS of potential impacts on HGP faell ities.

level of Effort:

0.4 FTE

,.

· .. ~ "

Task 3F: Induced Seismicity

Description:

- -8-

o DE-AI05-930R22089

The USGS shall investigate the- potential for induced seismicity from reinjection of spent geothermal fluids. USGS also shall evaluate methods to distinguish between natural and induced seismicity by using data from other regions and existing theoretical models. Results shall be compared with background seismicity which is addressed in Task 3D.

Justification:

It is necessary to distinguish between natural and induced seismicity to establish responsibility for damage resulting from earthquakes. HGP facilities would require seismic instrumentation to monitor induced and natural events. Knowledge of induced seismicity is required to support analysis in the EIS_of potential impacts from HGP facilities.

Level of Effort:

0.2 FTE

Task 4: Coordination of USGS Work and Peer Review of Draft HGP EIS

Description:

The USGS shall designate a technical coordinator for its contributions to the HGP EIS, who will provide technical and editorial guidance (1) to assume that a scientifically sound and coherent set of reports are prepared by scientists working on the separate designated tasks, (2) to monitor progress and deadl~nes, (3) to e~it and supervise internal USGS reviews of the preliminary reports to DOE and the final USGS Open-File Reports, and (4) eventually to coordinate USGS review of the ground water and geology sections of the Draft HGP EIS. The EIS review shall examine pertinent sections for technical accuracy and completeness. This review also shall examine impact analyses and the assumptions on which they are based. Overall responsibility for USGS participation in the HGP EIS and for coordination with DOE will continue to be through Dr. Peter W. Lipman (Menlo Park), who manages the Volcanic Hazards Program and the Geothermal Research Program of the USGS.

Justification:

A single technical advisor is needed to coordinate the 15-20 USGS scientists who will contribute information to the tasks described above, especially in light of the short time frame for completing reports, issuing publicly accessible documents (as USGS Open-File Reports), and promptly reviewing the draft HGP EIS. For review of the geologic sections

o -9- DE-AI05-930R22089

of draft HGP ElS, the USGS has a staff of recognized professional geologists with extensive experience in Hawaii. Their unbiased review is crucial in validating the accuracy and completeness of these sections of the HGP ElS.

Level of Effort:

0.5 FTE

Approximate Total Level of Effort (Task 1 to 4)

3.9 FTE

III. COST

The DOE hereby obl igates $496,710 for actual cost to support work performed through June 30, 1994. The current obligation is based on the following budget estimates:

For clarification, a summaryr. of funding for each task is shown on Page 10.

Re: Notification of Intent to Clean Out Scientific Observation Holes (SOH) Prior to Release of Tonto U5000 Drilling Rig for DLNR's Review and Comment

Dear Mr. Tagomori:

On June 13th, the SOH program was asked to put the Tonto drilling rig, which was completing work on the HGP-A well in preparation of shutting in the well, on standby until the venting accident at the Puna Geothermal venture operation was resolved. The SOH program now recommends that the following described operations be initiated to remove the temporary bridge plug from the HGP-A well and to shut in HGP-A; to clean out SOH-1, SOH-4, and if necessary, SOH-2 to allow logging and monitoring; and to release the Tonto U5000 drill rig for demobilization back to the Mainland. All operations will be conducted on a day shift basis. At present, rig costs and equipment rentals are accruing to the state at a rate of approximately $3,000 per day.

PICHTR is contractually obligated to remove the plug used in the Downhole Coaxial Heat Exchanger (DCHE) research. In any event the plug must be removed to leave HGP-A in a condition so that the well can be utilized in the future. PICHTR will manage and be responsible for rig operations during the removal of the bridge plug from HGP-A and the shut in of the well.

To leave the SOHs in a condition required for future monitoring and logging, it will be necessary to clean out any rock fragments proj ecting into the slotted tubing used in the hole completion, and to remove any accumulations of mud or debris


o -2- o in the holes. SOH land SOH-4 were completed with holes drilled in the completion tubing and will require clean out. SOH-2 was flushed and completed with slotting tubing, and may not require to be cleaned out. SOH-2 will be plumbed to determine if a clean out is necessary. All operations will be conducted in accordance with permits approved by DLNR and the county of Hawaii, and in a manner to contain all fluids and reduce any possible risk to an absolute minimum.

During drilling operations at the SOHs no H2 S was released, nor were the noise limitations exceeded. No H2S emissions are expected during clean out operations. All clean out operations will be conducted with kill lines and pumps connected to ample water storage tanks, and BOP equipment on the hole. Also during drilling operations, the Tonto U5000 rig was extensively modified to reduce drilling noise. This equipment is presently on the rig and will be utilized during the remainder of the program.

After clean out operations on the SOHs are completed, the si tes will be cleaned and restored in accordance with permits approved by DLNR and the County of Hawaii, and the Tonto U5000 drill rig will be released for demobilization to the loading dock at Hilo harbor and for transportation back to the Mainland.

Details of the clean out plan and schedule are included in the accompanying letter entitled "Schedule and Plan for Scientific Observation Hole (SOH) Clean Out and Release of the Tonto U5000 Drill Rig".

As mentioned previously, PICHTR will manage and be responsible for rig operations during the removal of the bridge plug from HGP-A and the shut in of the well. Procedures for the bridge plug removal and well shut in are provided in the accompanying PICHTR memo entitled "PICHTR DCHE Project, Procedure for Bridge Plug Removal at HGP-A". The SOH program provides for a nominal six days for PICHTR operations at HGP-A to be completed. Actual time, as estimated by PICHTR, at HGP-A may be less. In any event, mobilization to SOH-4 (Day 7) will commence immediately after rig down at HGP-A.

PICHTR DCHE Project Procedure for Bridge Plug Removal at HGP-A

Background: The PICHTR DCHE system tests were completed in March. Following completion of the SOH-2 well. the Tonto rig was relocated to HGP-A in early June. in order to remove the DCHE tubing and the bridge plug from the well. The tubing was removed on June 9 and work in progress to remove the bridge plug was discontinued on June 13. 1991. by direction from DBED.

Purpose: The purpose is to complete the removal of the bridge plug. per the Facilities Use Agreement with the Natural Energy Laboratory of Hawaii Authority (NELHA). Removal of the plug will complete PICHTR's obligations to return the well to its original condition.

~: Based on past experience with the HGP-A well. no problems are anticipated in maintaining safe well conditions during this procedure. In addition. no release of hydrogen sulfide is expected. Measurements will be performed with assistance from the state Department of Health (DOH)] during this procedure to monitor for possible hydrogen sulfide emissions. Should there be any release of hydrogen sulfide or problems with the well. remedial actions will be accomplished according to the PICHTR Safe Operating Procedure (SOP). dated December 19. 1990.

Procedure: The following steps will be taken:

Day 1: Removal of the bridge plug

I) Per the SOP. the well conditions will be checked. Should there be negative pressure or no water at the wellhead. fresh water will be pumped into the well to bring the water level to the surface and to -maintain the "wellhead pressure .at ambient. Should there be positive pressure at the wellhead. water will be pumped into the well to reduce the pressure to ambient. During steps 2 t~ 7. water will be pumped into the well to maintain ambient pressure at the surface.

2) The damaged tool parts (from the first attempt to remove the plug) will be removed using a wireline and a special. magnetic fishing tool;

3) The bridge plug retraction tool will be assembled onto the first section of 5" drill pipe with assistance from Halliburton;

4) The tool will then be inserted into the well on a string of 5" in drill pipe (40 foot sections);

5) With assistance from Halliburton. the tool will be inserted into the bridge plug and the upper bridge plug jaws wililile milled using the millshoe of the retraction tool;

6) The plug will be engaged with the tool and removed from the well;

7) The main well valve will be closed: and

8) Derigging will be initiated

Day 2 (and 3, if necessary): Derigging and Staging

9) The crew will complete de rigging and stage the rig for transport to the SOH-I site.

o Safe Operating Procedure - Final Downhole Coaxial Heat Exchanger Phase 1 - Proof of Concept Experiment Pacific International Center for High Technology Research December 10, 1990

o

This Safe Operating Procedure (SOP) was prepared as a tool for systematically evaluating the environmental, safety, and health hazards that may occur during the course of conducting Phase I of the Downhole Coaxial Heat Exchanger Experiment at the HGP-A site.

1.0 INTRODUCTION

1.1 Background

The Downhole Coaxial Heat Exchanger (DCHE) project has been initiated as a joint PICHTR and Japanese collaboration to investigate the commercial viability of the DCHE technology. There is a formal agreement, Memorandum of Understanding (MOU), between PICHTR and ENAA which encompasses three phases of activity. Phase I is a "proof of concept "experiment, Phase II is a pilot power plant demonstration, and Phase III is marketing and commercialization of the technology. The estimated funding required for Phase I is $560K.

Funding and support is from three sources: $280K from the PICHTR via the State of Hawaii; $280K from the Engineering Advancement Association (ENAA) and the DCHE-Japan consortium in Japan. ENAA is funding Sumitomo Metal Industries, Ltd. as the lead company in the DCHE-Japan consortium consisting of Sumitomo, Kawasaki Steel, Ltd., Kubota, Ltd., and Mitsui Engineering & Shipbuilding, Ltd.

The intended application of the DCHE technology is for production of electricity from "Hot Dry Rock" geothermal reservoirs. Hot dry rock (HDR) reservoirs occur where there is geothermal heat but insufficient steam for generation of electricity utilizing conventional geothermal technology. For the purposes of the PICHTR project, the existing HGP-A well will be temporarily reconfigured to simulate a HDR. This will be accomplished by sealing off the bottom section of the well by installing a removable, mechanical bridge plug (sometimes referred to as a "packer") at a depth approximately 3000 feet.

Briefly (the DCHE technology is described in more detail in section 4), the DCHE technology provides a method for transfer of the heat in the well to the surface by circulating fluid in a closed system. The key system components are the well casing, bridge plug, insulated tubing that is inserted into the well to a depth slightly above the bridge plug, circulating pumps and controls at the surface. Water will be injected at the surface at approximately 20 gpm and at slightly elevated pressure, flow around the outer surface of insulated tubing down to 3000' depth and return to the surface through the center of the insulated tubing (after being deflected by the bridge plug).

1.2 Project Management

• •

• •

" II

The overall responsibilities for the project are specified in the ENANPICHTR I Memorandum of Understanding (MOU) and are summarized as follows. ENAA and DCHE-Japan will design, fabricate and deliver the DCHE System to the test site on Hawaii. PICHTR will install, test and provide the test results to I ENAA and DCHE-Japan.

Once the test data have been delivered to ENAA, ENAA will analyze the data I to compare the calculated heat transfer rates (from the test results) with the • computer-generated predictions. A summary report will be prepared by the project team. This report will provide input for the decision about proceeding to I Phase II of the project.

2.0 OBJECTIVES

The primary objective of the Proof of Concept experiment is to measure the heat transferred via fresh hot water and/or steam in a closed system (DCHE) from 3000 feet deep in the HGP-A well to surface. Specific objectives are:

1) To confirm automatic operation and capability of the DCHE System to circulate fresh water in a closed system from the geothermal well to the surface,

2) To measure the temperature, pressure, and flowrates of the fresh water (steam) as injected and withdrawn from the geothermal well,

3) To calculate the effective heat transfer rate of the DCHE System,

4) To compare the measured heat transfer rates with the Japanese model, and

5) To make recommendations on proceeding with the Phase II Pilot Plant experiments.

In general, the DCHE system will be operated in a continuous, automatic, attended mode. The operation is basically "on" or "off", i.e. the operational parameters will not be varied during the test period. Data collection will be also continuous. The test site will be manned on a continuous basis during the planned, 24-hour/day, for a minimum 7-day up to a maximum 30-day test period.

3.0 DESCRIPTION OF TEST SITE

o

The Downhole Coaxial Heat Exchanger will be installed and tested at the HGP-A site on the Big Island of Hawaii, USA. The 4 acre HGP-A wellsite (see Figure I) is located about 21 miles from Hilo (Hilo is roughly 40 minutes by inter-island jet from Honolulu) on the Kilauea volcano's East rift zone near Pahoa in the Puna district.

The Puna district has a semi-tropical climate with an annual precipitation of 125 inches and an average solar insolation of 360.8 cal/square cm/day. Winds generally average 11 miles per hour from the northeast.

The area is zoned for agriculture, and while the local sugar company terminated operations, papaya farms and other diversified agricultural activities are still operated. The nearest residence is approximately one-half mile to the northwest of the site.

The HGP-A well was completed in 1976 (Reference 1). It extends to a depth of 6435 feet. There is a 7 inch I.D. steel casing that extends to 3000 feet. There is a slotted liner that begins at the 3000 feet depth and extends to the bottom of the well.

Tests will be performed prior to the installation of the DCHE System to confirm the condition and integrity of the well casing, as described in a separate procedure (Reference 2).

4.0 DESCRIPTION OF THE TEST CONFIGURATION AND DCHE SYSTEM

The overall test configuration, illustrated in Figure 2, consists of the DCHE System, a temporary storage tank, rock muffler, and external heat exchanger.

4.1 DCHE System

The DCHE System consists of two major components - the insulated tubing (installed below the ground) and the support system (installed above the ground) as depicted the system schematic (Figure 3).

4.1.1 Insulated Tubing

ENAA will provide 3000' of insulated tubing. The tubing is 3.5" 00 with a 0.75" insulation layer, i.e., the ID is 2.0". The tubing weighs approximately 13.3 pounds/foot for a total installed weight of approximately 40,000 pounds. The tubing will be installed with and supported by the Tonto drilling rig.

4.1.2 DCHE Support System

o

Note: for these tests the DCHE support system replaces the turbine-generator that would be used in an operating DCHE power plant to generate electricity. The primary functions of the DCHE support system are as follows:

1) To circulate ~ water in and out of the well

2) To provide for measurements of the heat transferred to the surface via the DCHE circulating water

3) To provide a safe route for the release of steam (if necessary)

Note: Analysis of the operation of the DCHE system for the expected HGP-A well conditions indicates that the maximum continuous circulating wake temperature (at the surface) will be 86.60 C. Therefore, steam (if it reaches the surface) is not expected on a continuous basis.

4) To provide for safety and corrosion control methods to protect personnel and equipment, including the well casing, and the community

The DCHE support system includes a motor control unit/electrical panel, instrumentation sensors with a "patch" panel, a steam separator tank with steam-release vent, "make-up" water tank, chemical pump, circulation pump, and cooling water pump.

Primary controls for the Phase I experiment are:

1) Circulation water flow control consisting of a control valve linked to flowmeter. The control valve and flowmeter are located just downstream of the circulation pump and controls the flowrate of the water being injected into the well.

2) A pressure controlled valve which regulates the flow out of the DCHE.

3) A water level control that adds more water to the circulation system as needed.

4.2 Temporary Storage Tank

A temporary storage tank with a storage capacity of 7,000 gallons and pump will be available (if needed) for supply of emergency cooling water to the well. The tank and flushing of the pump can be used for temporary storage of circulating DCHE fluids.

7


4.3 Rock Muffler

o

The steam vent pipe from the DCHE support system will be connected to the HGP-A's secondary rock muffler. The rock muffler location is indicated in Figures 1 and 2.

4.4 External Heat Exchanger

PICHTR will provide an external heat exchanger for cooling of the DCHE output water (estimated up to 90 degrees C) for reinjection to the well at 40 degrees C. The external heat exchanger is a "tube-in-shell" design that will be provided by NELHA. A secondary heat exchanger (special air-exchange cooling system) will be used to provide the cooling water for the external heat exchanger. Both heat exchange systems will be operated at pressures less than 100 psig. Since both systems are designed for high pressure (greater than 200 psig) operation, there will be a margin of safety for their use on the DCHE tests.

5.0 DISCUSSION OF HEALTH AND SAFETY CONCERNS AND GENERAL HAZARDS

The health and safety of all personnel and equipment involved in these tests, the site and the community is paramount. The primary health and safety concerns are the prevention of hydrogen sulfide release to the atmosphere and maintaining safe well conditions.

5.1 Hydrogen Sulfide

Since the well will not be flowed during these tests, the overall probability of detectable H2S emissions beyond the site boundary is considered very low and should not present a community nuisance issue or health hazard. The well conditions will be monitored continuously to ensure compliance with the State Department of Health notification requirements on H2S emissions. Should there be H2S emissions during the installation, operation, and removal of the DCHE system, appropriate action will be taken. The discussion below and procedures described in sections 7 and 8 reflect careful attention and diligence in addressing this health and safety concern.

P II

I ! I I I I I I I I I I I I I I

JIIIIIII

"-E I I I I I I I


5.2 Well Conditions

o

The well conditions will be monitored continuously to identify changes in well pressure or temperature, content of circulating DCHE fluids, and integrity of the closed DCHE system. The discussion and procedures described in sections 6 through 8 reflect careful attention and diligence in addressing this health and safety concern.

5.3 Chemicals

Chemicals for corrosion inhibition will be used for protection of the well's steel casing and the insulated tubing (part of the DCHE system) that is inserted into the well during the test. An industry-accepted chemical will be selected for insertion, via an automatic feed system, into the DCHE circulating water. The manufacturer's recommended procedures for storage, handling and usage will be followed by all DCHE personnel.

Bottled nitrogen gas will be used to maintain an inert atmosphere inside of the DCHE water storage tank. Several high pressure cylinders will be required; they will be connected to a common manifold. The cylinders will be secured to a rigid and stable structure.

5.4 Material Handling

The Tonto Drilling rig will be used to insert the insulated tubing into the well. Other heavy equipment may require special handling with mechanical assistance, such as a hydraulic crane or forklift. Only certified, trained personnel will operate the equipment and only authorized personnel will be allowed in the test area during this operation (See also section 5.10).

5.5 Electrical

Since 480 voltl3 phase electricity will be supplied and utilized by the DCHE system, a visible, lockable disconnect switch will be installed per the National Electric Code. The power will be disconnected and the switch locked when the system is not under test.

Note: As an additional safety precaution, only authorized personnel will be allowed in the test area during installation and test operations (See also Section 5.10).

5.6 Noise

To ensure compliance with County of Hawaii requirements on acoustic (noise) emissions, PICHTR will monitor acoustic levels. If needed, noise generating sources will be insulated to reduce the noise emissions to within

9


o

the County of Hawaii noise regulations. Current requirements are that noise levels shall not exceed 55 dBA at the nearest residence during daylight hours; 45dBA at night. An acoustic monitor will be located and operated at the northwest site boundary in line with the nearest residence. In addition, periodic measurements will be made at the nearest residences to ensure compliance.

5.7 Hot Fluids

Since the temperature of the geothermal heated DCHE fluids pumped out from the well could exceed 250 degrees F, only authorized personnel will be allowed in the test area. See also Section 5.8.

1. The Tonto Drilling rig will be used to insert the insulated tubing into the well.

2. Only certified, trained personnel will operate the equipment.

5.8 DCHE System Failures

The primary two primary system failures of concern are loss of system integrity due to failure of the bridge plug, well casing, or one of the pumps or valves; rupture of pipes or connecters. These failures can result in damage to equipment and potential hazards to personnel.

Note: the DCHE support system operations manual discusses the methods of automatic detection of and corrective action for the DCHE support system failures. Loss of system integrity will also be detected in variations of the well conditions (see section 7.4). Given assessment of these variations, appropriate countermeasures can be taken (see section 7.5).

In addition, operation and test personnel will physically inspect the system periodically to detect component failures and to take corrective action. Specifically, if any component failures or leaks are detected, the system will be shutdown per section 8.1. Maintenance and repairs will be accomplished according to the DCHE system operation manual and other pertinent sections of this SOP.

5.9 Natural Events

DCHE personnel mayor may not have advance warning of impending natural events, e.g., volcanic eruptions, hurricanes, storms, etc., which may affect the operation. The following actions will be taken:

1) All on-site and key DCHE personnel will be alerted; date and information

o

1) All on-site and key DCHE personnel will be alerted; data and information will be gathered and forwarded to the PICHTR Project Manager and NELHA Technical Director;

2) A decision will be made by the Project Manager (in consultation with NELHA) on whether to terminate operations; the County of Hawaii Civil Defense officials will be informed of the decisions made and measures taken;

3) If a decision is made to terminate the tests, the well, the drilling rig, the DCHE system, auxiliary and test equipment shall be secured or disassembled and removed, as appropriate and with time permitting; and

4) All non-essential personnel will be evacuated.

5.10 Authorized Personnel

The DCHE Project Manager will establish and maintain, in consultation with NELHA, a roster of personnel authorized to be on the HGP-A for participation in the DCHE project. No other personnel shall be allowed on the site without approval.

6.0 SITE PREPARATIONS

Prior to the installation of the bridge plug and DCHE system, site preparations will be accomplished as discussed below.

6.1 Wellhead Modifications

a) To provide fail-safe protection of the well during the installation, operation and removal of the DCHE system, a double-gate, blow-out-preventer (BOP) will be installed on the well. Specifically, the BOP will be mounted directly to the top of the root (main) valve, after all valves and flanges above the root valve have been removed

b) The well pad will be used to provide support for the drilling rig as follows:

• A platform will be designed, fabricated and installed onto the "lip" of the caisson.

• The platform will be supported by beams which will transfer the primary loads to the wellhead foundation.

11

________________________ !!O!Mli"'· ... '~,~


6.2 Site Modifications

a) Support Structure for steam lines from the wellhead to the turbine generator building and the metal frame ("cat walk") that is mounted to the caisson will be removed to allow access of the drilling rig to the wellhead.

b) An existing storage tank (previously used on the HGP-A power plant) will be available for storage of cooling water for use in hydrogen sulfide emission (Section 7.3) and well conditions (Section 7.5) countermeasures. The appropriate lines and pump will be installed and connected to a high pressure valve at the root of the wellhead.

7.0 GENERAL HEALTH AND SAFETY PROCEDURES

As discussed in section 5, the primary health and safety concerns are prevention of H2S emissions and maintaining safe well conditions. These procedures for assurance of the health and safety of the project team, the equipment, the site and the community are discussed in this section. If needed during the installation, operation and removal of the DCHE system, the implementation of these procedures is indicated in section 8 by specific reference (s) to this section.

7.1 Wellhead Pressure Measurement

Prior to the installation of the DCHE system or at other times as prescribed in section 7 and 8, the following procedures will be implemented to measure the wellhead pressure:

a) Open the "kill-line" valve at the root of the wellhead

b) Open the 1-in "gate" valve to the pressure gage

c) Read and record the pressure level on the gage

d) Close both valves

e) Report the pressure reading to PICHTR and NELHA management

I I I I I I I I I


7.2 Wellhead Pressure Equalization

o

If, after procedure 7.1 it is found that the wellhead pressure is above ambient, the following procedure will be used to equalize the wellhead pressure to ambient:

a) Attach a water line, capable of providing cool water at a pressure greater than measured in procedure 7.1, to the "kill-line" valve

Note: Since a water capacity of up to 7,000 gallons may be required, the temporary storage tank (configured with a pump and attached to the water line) will be used. As an alternative, a watertank truck can "stand-by" during this procedure as a "back-up", or could provide the primary source for the water.

b) Energize the pump prior to opening the "kill-line" valve

c) Open the "kill-line" valve and deliver water to the valve

d) Monitor the wellhead pressure continuously (see procedure 7.1)

e) Add water until the wellhead pressure is reduced to ambient

f) Turn off the supply of water and close the "kill-line" valve

7.3 H2S Emissions Countermeasures

At all times during the installation, operations and removal, atmospheric conditions will be monitored to detect the emission of H2S from the well. If emissions occur above ambient levels, PICHTR will notify NELHA. NELHA will notify the State of Hawaii per NELHA policy. Should the levels persist after countermeasures are taken, the test (if in progress) will be terminated as discussed below.

Note: A source of water with a capacity of up to 7,000 gallons is required for possible H2S emission countermeasures. The temporary storage tank (configured with a pump and attached to the water line) will be used. As an alternative, a water tank truck can "stand-by" during this procedure, as a "back-up", or could provide the primary source for the water.

13

------------------------'*,«~"'-,


Should H2S emissions be detected during these three periods, the following procedures will be implemented:

a) During the equalization of the wellhead pressure prior to installation of the bridge plug

Countermeasure. Immediately increase the flowrate of the water supply to the "kill-line" valve (see procedure 7.1). If this countermeasure is not effective, immediately close the "kill-line" valve and secure the well.

b) During the installation and the removal of the bridge plug

Countermeasure. Immediately increase the flowrate of the water supply to the "kill-line" valve (see procedure 7.1); if this countermeasure is not effective, immediately close the "kill-line" valve, and, if the drill pipe is still in the well, engage the BOP to seal the drill pipe; if this countermeasure is not effective, implement an emergency shut down, per procedure 8.1.

c) During operation of the DCHE system

Note: Since the circulating DCHE fluid will be fresh water, no hydrogen sulfide is expected. If there are hydrogen sulfide emissions during operations, it will indicate a possible loss of well integrity. Proceed to procedure 8.1 and investigate possible causes, such as failure of the bridge plug. See also procedure 7.5 (c).

7.4 Monitoring and Assessing General Well Conditions

The following parameters will be monitored in order to assess the general well conditions:

a) Temperature of DCHE circulating water, both at the surface and in the bottom of the system (approximately 3000' depth)

b) Pressure of the DCHE circulating water at the surface

c) Flow rate of the DCHE circulating water out of and into the well

d) Chemical (saline content) properties of the circulating DCHE water

14

• -.. ..

I I I I I I I I I ! I I I

-• -.. i I I I ~

C [

i I I I I I I I I


The following assessments will be made:

a) Whether the well is cooling off or heating up

b) Whether there is potential blockage or leakage in the DCHE system

c) Whether there is a net flow of fluids in or out of the DCHE system

7.5 Well Condition Countermeasures

For the well conditions as assessed in procedure 7.4, countermeasures will be implemented as discussed below.

a) If there is an indication that the well temperature is dropping, indicating cooling, it is not considered a hazardous condition. The tests will continue (if desirable) until the time that the temperature of the circulating fluid, as it exits the well, is the same as the temperature of the circulating fluid as it is reinjected into the well (nominally 40 degrees C).

Countermeasures. No countermeasures are required. The tests may be terminated per procedure 8.1.

If there is an indication that the well temperature is increasing, indicating heating, it is not considered a hazardous condition, unless the rate of temperature increase is greater than 1 degree C per hour, or if steam is generated at the surface, requiring continuous release to the rock muffler.

Countermeasure. A normal shutdown (see procedure 8.1) will be implemented. If the well temperature continues to increase and/or the wellhead pressure also increases, procedure 7.2 will be implemented as a countermeasure to reduce the well temperature. A decision will then be made on whether to continue or terminate the tests.

Note: If the above countermeasures are ineffective, a potentially very hazardous condition is Indicated; an emergency shutdown (procedure 8.2) shall be implemented immediately.

15

-------------------------------,~~.""-


b) If there is a potential blockage in the DCHE system, this condition will be indicated by a variation or build-up of pressure of the Circulating water at any location in the system. If the variation in or build-up of pressure exceeds 25 psig, it is considered hazardous.

Countermeasure. A normal shutdown (procedure 8.1) will be implemented. An inspection will be made of all DCHE support system components to detect and repair a blockage. If none are detected and/or the pressure continues to

increase, procedure 7.2 will be implemented to reduce the well pressure. If this procedure is not effective, an emergency shutdown (procedure 8.2) will be implemented. A decision will then be made regarding termination of the tests.

If there is potential leakage in the DCHE system, this condition will be detected by a variation or net increase in the flow rate of the injected water, compared to the flow rate of the exiting water and/or a loss of system water pressure. If there is 5% variation or increase in the flow rate or a 5% drop in system pressure, it will be considered a hazardous condition.

Countermeasures. A normal shutdown (procedure 8.1) will be implemented. An inspection will be made of the DCHE system to identify source (s) of leakage; repairs will be effected. If none are detected, there is an indication of either a loss of the bridge plug or a failure of the well casing. The presence of the bridge plug will be verified either by insertion of a probe or by extension of the insulated tubing. In any case, immediately following the determination, an emergency shutdown (procedure 8.2) will be implemented. A decision will then be made regarding further countermeasures or termination of the tests.

c) If there is a net flow of fluids in or out of the DCHE system, this will be detected by a variation of net increase or decrease of the flow rate of the exit water compared to the injected water. This condition may indicate a failed bridge plug or a failure of the well casing.

Countermeasures. A normal shutdown (procedure 8.1) will be implemented. An inspection will be made of all DCHE support system components to detect and repair a blockage. If none are detected, the presence of the bridge plug will be verified either by insertion of a probe or by extension of the insulated tubing. In any case, immediately following the determination, an emergency shutdown (procedure 8.2) will be implemented. A decision will then be made regarding repairs and further tests or termination of the tests.

8.0 Shutdown Procedures

There are three shutdown procedures which will be implemented during normal, emergency, and critical conditions as discussed below.

8.1 Normal Shutdown

8.2

a) Discontinue DCHE system operation (if operating); ensure that the BOP seal on the insulated tubing is secure

b) Monitor well conditions (wellhead pressure, well temperature, if available) continuously

Emergency Shutdown

a) Discontinue DCHE system operation (if operating)

b) Monitor well conditions (wellhead pressure, well temperature, if available) continuously

c) Remove the insulated tubing from the well

d) Close the master valve

Note: if there is not sufficient time to complete the emergency procedure in a safe manner, implement a critical shutdown.

8.3 Critical Shutdown

If, in the judgement of the DCHE Project Manager and, after consultation with NELHA, all correction actions and countermeasures have failed to remedy unsafe conditions; and an extremely hazardous condition exists in the well, the following will be the procedure of last resort:

a) Engage the BOP and ABANDON ANY EQUIPMENT in the well

b) Close the master valve

c) Secure the drilling rig

d) IMMEDIATELY EVACUATE all NON-ESSENTIAL PERSONNEL from the SITE

e) Notify emergency support personnel for assistance

17

-------------------------------------"'~-"'"'~,,


9.0 Test Termination Procedures

Following successful completion of the planned tests, a normal shutdown procedure will be implemented per procedure 8.1. The DCHE system, drilling rig and all equipment will then be removed per sections 10.7 to 10.10.

Termination of tests may also occur for any of the following conditions:

a) Loss of proper system operation or DCHE support system, cooling system or data system failures, or

b) Loss of system integrity, including bridge plug, casing, tubing or other failures, or

c) Environmentally unsafe conditions, or

d) Unsafe well conditions

10.0 Installation, Operations and Removal of the DCHE System

Note: A drilling company will be under contract to PICHTR to provide the following support to the DCHE project: installation/removal of the BOP, installation/removal of the bridge plug, and installation/removal of the insulated tubing. These activities will be under the direction of PICHTR with assistance from a geothermal drilling consultant.

10.1 Drilling Rig Set-up and Check-out

Note: The drilling rig will be an integrated, highly portable design. However, because of the size and location of wellhead "caisson" at HGP-A, a special support structure (described in section 6.1) and special procedures (in addition to the drilling company's normal procedures) are required to complete the drilling rig set-up.

To complete the set-up and check-out:

a) Relocate the drilling rig to the HGP-A site

b) Position the rig next to the well

c) Lift and temporarily position the rig above the caisson

d) Lower the rig onto the special support structure

Re: Geothermal Well Modification Permit

Dear Mr. Paty:

The Natural Energy Laboratory of Hawaii Authority (NELHA), a body corporate and a public instrumentality of the State of Hawaii organized pursuant to Hawaii Revised Statutes, Chapter 227 and Act 224, is the lessor pursuant to Geothermal Resources Mining Lease No. S-4602, and Agreement between HGP-A Development Group dated November 27, 1985.

The four acre HGP-A wellsite (see attached copy of a certified survey) is located apprOXimately 21 miles from Hilo on the Kilauea Volcano's East rift zone near Pahoa in the Puna District.


ApprOXimately (2) weeks ago, the United states Geological Survey (USGS) conducted an inspection of the HGP-A well. During this inspection test it was discovered that an obstruction in the well existed at a depth of approximately 2,133 feet.

After discussion and evaluation of the results we have determined that the obstruction must be removed in order to continue necessary testing of the well. Consequently, a drilling rig is needed for the removal of the obstruction.

The series of tests proposed by NELHA may include the following: caliper, borehole televiewer, temperature profile, and multifrequency casing inspection log.


o o

tinuities found in the well casing in the vicinity of the scaled interval. After the obstruction has been removed by coring and then reaming, a bridge plug will be put in place below the depth of the obstruction and topped with sand. Pressure tests will then be done to locate possible discontinuities.

Discontinuities will be sealed using a cement squeeze. If communication with the bore does not occur, perforation of the casing will be required. This will be followed by a cement squeeze operation to seal the casing. The cement inside the casing will then be reamed out and the well workover will be complete.

This well modification work is scheduled to begin January la, 1991.

If required, NELHA will file a bond meeting the requirements of Section 13-183-68 with the Chairperson, within ten calendar days after notification that the application has been approved.

Pursuant to Section 13-183-65(7) NELHA will perform the work and thereafter operate and maintain the well in accordance with these rules and all other Federal, State, and County reqUirements.
