SOHIO PETROLEUM COMPANY PLAN OF EXPLORATION NORTH PADRE ISLAND BLOCKS A-22 * A- 33

OCS-G-7146 4 OCS-G-71 SO OFFSHORE TEXAS

Pursuant to the requirements of 30 CFR 250.23.1, Sohlo Petrolei* Coapany

submits the following Plan of Exploration (POE) for North Padre Island Blocks A-22

I A-33.

(1) EXPLORATION ACTIVITY

The proposed exploration activity for North Padre Island consists of

dr i l l ing Uells "A, B S C froa three (3) different locations. All three locations

will be drilled as straight holes. The estimated time to dr i l l these three (3)

exploratory wells It about three nundred thirty (330) days, with a September 10,

1966 anticipated spudding date f c the "A" location.

(11) PROPOSED DRILLING RIG

Sohlo has under contract the Pentagon 82 owned by Forex Neptune. This 1s

a sea1-subevtrs1b1e type dri l l ing unit capable of dril l ing to 20,000' In water

depths of 1,200*. Rig specifications, BOP and diverter systaas are shown as

Attachment A.

(111) GEOPHYSICAL WORK

All of the geophysical work preparatory to Initiation of exploratory

operations has been com- 'ted. A velocity survey aay he run on these wells when

total depth has been reached. No other geophysical work 1s planned unless data

obtained froa drilling operations necessitates additional definition detail froa

conventional reflection seismic methods.

Two (2) copies of the shallow hazard rtport, "Hazard Study Blocks A-22 I

A-33, North Padre Island", prepared by John Chance A Assoc., Inc. are subnltted

with this POE.

Tht North Padre Island Blocks A-22 I A-33 Hazard Study has bttn reviewed

by Mr. Phil Hosemann, Sohlo's Regional Geophysicist. Attachments B-1 through B-3

are letters froe Mr. Hosemann 1n which he agrees with John Chance's conclusions

and addresses shallow hazards at each well si te.

Attachment C-1 Is a vicinity nap depicting th* subjtct tract 's position

r t iat ivt to tht Ttxas shoreline. No new onshore faci l i t ies will bt required for

dri l l ing thtst propostd exploratory walls. Existing service conpany fac i l i t ies In

the Corpus Christi, Ttxas Arta havt sufficient capacity to accommodate this pro­

ject without modification or expansion.

Attachnent C-2 shows the proposed surface locations for Wells "A, B A

C". The total depth, water depth and surface locations for each of these wells Is

as follows:

Structure mips and cross-sections are Included 1n tha f ive (5) confiden­

t i a l copies of this Plan as Attachments D-l and D-2. Depths shown on cross-sec­

tions and structure maps are sub-sea measurements.

( v l ) OTHER RELEVANT DATA

(A) Oil Spi l l Contingency Plan

Sohlo Petroleun Conpany Is a member of Clean Gulf Associates (CGA) and

would u t i l i ze that organization's equipnent to clean up an o i l s p i l l .

The closest CGA bases are at Corpus Ch r i s t i , Rockport and Fulton, Texas,

respectively. Respo.ise tines for CGA Fast Response Units fron these

three (3) locations would be 10, 11 and 12 hours, respectively. Manpower

to operate the CGA's equipnent would be provided by Peterson Marltlne

Services, Inc., whose personnel are trained for o i l sp in clean-up opera­

t ions. Sohlo's supervisory personnel would direct the clean-up opera­

t ions unt i l successfully conpleted. Additional details can be found In

Sohlo's 1984 011 Spi l l Contingency Plan which has been approved by the

Minerals Managenent Service.

(B) L i s t of Mud Components

Attachment E Is a 11st of the proposed d r i l l i n g mud components and addi­

t i ves , Including the comnon ard chemical trade name of each addit ive.

(C) Gaseous Emissions

Exploratory d r i l l i n g operations w i l l be conducted from the surface sites

described 1n Section ( l v ) using the mobile d r i l l i n g unit described In

Section (11). Operation*, w i l l be of a naxlmuw duration of three hundred

t h i r t y (330) days.

-3-

At thf dr i l l s i te, gaseous emissions will oe generated by th- rig en­

gines, the attenlant work boat, stand-by boat, crew boat, and helicopter,

and the production testing of possible prospective reservoirs. Gaseous

emissions at the dock site 1n Corpus Christi, Texas, will be generated by

the »ork boat, crew boat and helicopter. Onshore staging for this opera­

tion will be from existing fac i l i t i es , so there will be no significant

Increase In emissions for this activity. Projected emissions from this

activity have been calculated and are presented In the A1r Quality Review

as Attachnent F.

(0) Coastal Zorx Managenent (CZM) Consistency Certification

A Coastal Zone Managenent Consistency Certification is rwt required for

Texas.
