1. PowerPak Motors

1.1 Highlights

PowerPak is a positive displacement downhole drilling motor (PDM) powered by the circulatingdrilling fluid. The pressure drop across the motor is directly proportional to the drilling torquedeveloped at the bit. The rotational speed depends primarily on the circulation rate, and is onlyslightly affected by the torque.

1.2 Details

1.2.1 Cross-Over Subs, Dump Valves, or Flex Subs

Cross-Over Subs (or Top Subs) are available for simple connection from the drill string to thestator/motor. Cross-Over Subs are available for all PowerPak motor sizes. A Dump Valve allowsthe drill pipe to fill with drilling mud when running a motor into a well, and to drain whenpulling out of the hole. The valves close when the flow rate reaches a given threshold. DumpValves are only available for motor sizes 4-3/4 through 11-1/4. Flex Subs are available for 3-1/8 through 9-5/8 motors. These replace the dump valve or cross-over and help prevent failureof the stator connections by reducing the bending stresses. Dump valves should only be run whenrequired by the Client.

1.2.2 Power sectionThe power section, consisting of a stator and rotor, converts hydraulic power from the drillingfluid into mechanical power to rotate the bit. It operates by the reverse application of theMoineau pump principle. The stator is composed of an elastomer with a helicoidal lobe patterncross section, with n lobes, molded inside a steel housing. The rotor is a machined stainless steelshaft, with a cross section similar to the stator, but with n-1 lobes. The contact of elastomericstator lining and metal rotor surfaces forms continuous sealing lines and multiple closed fluidchambers. When drilling mud is circulated through the power section the rotor is forced to rotate.Rotors/stators are available in various configurations: with standard or extended length sections,standard or over-sized (OS) stators, and standard or undersize (US) rotors. Refer to the masterorders for details. Chrome plated, tungsten carbide coated and non-plated rotors are available.Tungsten carbide plated rotors are recommended for salt-saturated or corrosive drilling muds.

1.2.3 Transmission sectionThis section transmits the rotary motion and torque produced by the rotor/stator down to thedrive shaft/bearing section of the motor. The transmission couplings also convert the eccentricrotation of the rotor to concentric rotation at the bearing section. This section also includes thesurface-adjustable bend housing. Heavy-duty transmissions are available for Extended PowerSections and special transmissions are required for 1:2, 2:3 and some GT lobe configurations.





1.2.4 Bearing sectionThe bearing section consists of both axial ball thrust bearings, and radial tungsten carbide sleevebearings. The M-Series motors are mud lubricated: part of the mud flow (4 to 10%) is divertedthrough the bearing section for cooling and lubrication. The S-series motors use a oil-filledsealed bearing assembly. The drive shaft runs through the bearing section and connects thetransmission shaft to the bit. Bearing housings are available with replaceable sleeve type orintegral blade stabilizers, with straight or spiral blades. RNBS sleeves are available on A475 andlarger motors.

2. Short Radius Drilling

2.1 Highlights

Anadrills Short Radius service utilizes a unique set of tools for drilling high build rate curves.This service includes custom designed motors for directional drilling and SlimPulse MWD (orwireline steering tool), with optional gamma ray, for real-time measurement and control of thedrilling assemblies.

Short Radius is defined as curves with build rates from 40 deg/100ft to 1.5 deg/ft . This equatesto curves with radii from 143 ft to 40 ft. Another definition of short radius is any curve requiringarticulated tools to drill. Anadrill has defined short radius as any curve from a 40ft radius andlarger that has to be drilled with articulated motors.

There are two versions of the short radius motor, the XF and the XC. The XF is fully articulated,able to pass through casing easily, and can achieve the highest BURs. It needs special handlingequipment, has to be calibrated, and requires special DD training. The XC has a 0-4° adjustablebend in place of the lower articulation, needs no special equipment, is not calibrated and needsno special DD training but cannot achieve the BURs of the XF. The XCs ability to pass throughsmall ID casing is limited by the high bit offset. The XC retains the upper articulation to definethe third touch point and prevent bending moments above the motor from affecting the powersection.

2.2 XF Tool Details

Anadrills XF short radius motor design is based on the existing PowerPak line. Modificationshave been made to the stabilization, the length of the bearing assembly, and the design of thepower section. Articulations, or knuckle joints, above and below the power section allow themotor assembly to pass through the high dog-legs and straight casing while leaving the motorsections straight. The articulations do not affect the build up rate (BUR) of the tool.





The BUR, or radius of curvature (ROC), is determined by three points of contact: the bit, near-bitstabilizer, and lower pad. This theoretical curve is adjusted primarily by shimming the lower pad,although the near-bit stabilizer diameter and bit diameter and length also have an effect. Morelower pad shims decrease the BUR, fewer shims increase it. The Calibration Programspreadsheet software predicts the theoretical BUR vs. the number of shims used. The top pad isshimmed until the diameter across the lower and top pads is just under hole size to stabilize thepoints of contact. These two pads act like an eccentrically adjustable stabilizer.

In cases with BURs less than 82°/100 the same motor used to drill the curve can bereconfigured at surface to drill the lateral section. For higher curve section BURs a build motorwith a higher fixed bend is used, followed by a lateral motor with a smaller fixed bend. Thesmaller fixed bend allows the stator section to pass through the high BUR curve to drill lowerdoglegs in the lateral. The short radius motor is also compatible with surface drill string rotationfor steerable control in the lateral. Surface drill string rotation depends on the dogleg severity inthe curve and the drill string design. All these factors must be carefully considered prior torotating the drill string.

The near bit stabilizer is positioned very close to the bit on the drive sub. The near bit stabilizeris replaceable and rotates with the bit. This eliminates the problems associated with drilling stepprofiles common with highly offset motors. An articulation bumper between the lowerarticulation housing and the offset housing permits bending towards the tool face only. Thisstiffens the motor sideways for better directional control.

Figure 2-1 XF Articulated Motor FeaturesThe PowerPak XF articulated motor is capable of drilling 40 ft radius curves. The build pads are

easily reconfigured in the field to adjust the build rate. The 475XF is illustrated above. Thearticulation bumpers are not shown.





2.3 XC Tool Details

Anadrills XC short radius motor design is very similar to the XF except there is no near bitstabilizer and the fixed bend and lower articulation are replaced by a 0-4° surface adjustablebend. The power section, upper articulation, float valve housing, and UBHO are identical to theXFs.

The BUR of the XC system is determined by three points of contact: the bit, kick pad, and toparticulation. This is very similar to a normal steerable motor except that the articulation definesthe upper touch point very accurately as opposed to a normal slick steerable assembly where thethird point of contact can vary considerably with WOB and stiffness differences above the motor.The BURs can be calculated for different kick pad heights and hole diameters using the DoglegPrediction Program. This Excel Spreadsheet program can be acquired from SOPHIA.

Figure 2-2 XC Articulated Motor FeaturesThe PowerPak XC motor has a 0°-4° surface adjustable bend and is capable of drilling 65-70 ft

radius curves. The 375XC illustrated above.

3. 6 3/4 Geo-Steering Tool

3.1 Highlights

The 6.75 inch GeoSteering Tool (GST) is based on a standard mudlubricated Anadrillsteerable downhole motor with the addition of a 4 ft. long nearbit measurement sub (NBS). Italso includes an instrumented fixed bent housing integrated between the motor bearing sectionand the surface adjustable bent housing. The fixed bend is located at a distance of 5 ft. from thebit face and is currently available in angles of 0.75°, 1.25°, and 1.5°. The NBS is an oil-containedunit that carries the drive shaft in its center for the transmission of mechanical energy deliveredfrom the power section above to the motor bearing section and the bit below.

The NBS is a self-contained multi-sensor assembly that provides toroidal bit resistivity, lateralarc resistivity, gamma ray, inclination, tool face, and motor RPM information. Measurements aremade at a distance of 2.5 to 8 ft. from the bit face. The NBS uses wireless telemetry (E-mag) tocommunicate with a Receiver sub (RCV) or RAB above the power section so that no directwiring through the motor or other drill string components is needed. The RCV or RABcommunicates with the MWD tool higher in the drillstring through the LTB. The NBSinstrumentation is powered by lithium battery cells. The RCV is powered directly from MWDthrough the LTB.

With each start up of the pumping cycle, the NBS will transmit its survey data (inclination,gravity tool face, total G., and battery voltage) to complement the survey data from the MWDtool. The NBS then enters drilling mode where it transmits bit and arc resistivity, gamma ray, andRPM data. The bit resistivity measurement is capable of operating in all types of mud, whereasthe arc resistivity is accurate only in conductive environments. The gamma ray measurement isnot affected by any kind of mud system, but requires a small geometric borehole correction.

With M3 and M10 (PowerPulse) service, the GST offers formation logging capability duringwashdown jobs in an azimuthal referencing mode with reduced surface RPM. Resistivity andgamma ray data from the GST can then be correlated to the sensor orientation with respect to theGST tool-face measurement to provide resistivity up/down data and gamma ray up/down data forGeoSteering purposes.

Version 6.0 of GST downhole software allows for running the RAB tool in combination with theGST. This brings several benefits while GeoSteering:

• Obtain a lateral style resistivity and images on GST runs

• Eliminates the Receiver Sub from the BHA

• Easy to use azimuthal measurements for up/down steering decisions

• Add the dimension of Real-Time Dip to GST runs





If a RAB / GST combination run is planned, contact SPC-Engineering for current downholesoftware compatibility. The RCV must have version 3.4F or higher when used with GSTsoftware v6.0. Operation and testing in this configuration is also much different than the standardGST/RCV operation. Refer to the latest operating guidelines from engineering for details.

3.3 RCV-CA 6 3/4 Receiver Sub

The Receiver sub (RCV-CA) is currently available in a 6-3/4" size. Its main function is as a realtime communication link between the GST or RAB and MWD. Data is communicated upholefrom the GST/RAB via E-mag telemetry. This data is then passed on to MWD via LTBcommunication.

The RCV is compatible with M3 or PowerPulse but cannot be used with the M1 telemetrycartridge. The upper end of the RCV is equipped with a MEXU-BA extender. The lower end isdesigned to simulate the bottom end of the M10. It is recommended that a saver sub be usedbelow the RCV if a Non-mag collar is to be screwed into this end.

The RCV sub comes equipped with an 8" screw on Non-mag straight blade stabilizer. Thisstabilizer is compatible with the PowerPak screw on stabilizer, but it is recommended to use aNon-mag version if possible. The alloy steel stabilizers may have some adverse effects on theD&I sensors in MWD. Changing the stabilizer on site is not recommended, but can be done if theproper tools are present.

Connecting to M10 With IWOB

The RCV sub has a unique design that eliminates the need for a saver sub when connectingdirectly below M10. The RCV is designed to be made up directly to the M10 collar (without theSaver sub). When this is done, the lower M10 extender must be replaced with a standard femaleextender for LTB communication to the RCV. If CDR is being run below the RCV sub the lowerM10 saver sub (MSSA-BA) is then to be used below the RCV in combination with the lowerM10 extender (MEXD-AA).

The standard lower saver sub and extender must be used on the bottom end of M10 in theabsence of a special length LTB extender. It is also recommended that a saver sub be usedbetween the RCV and CDR if this connection is to be made up on the rig. The use of this sub willrequire a lower M10 extender (MEXD-AA).

Connecting to M3

The RCV sub is made up to M3 using a LSS-BA or LSS-BB Saver sub. If CDR is run below theRCV sub a Saver sub (MSSA-BA) should be used in combination with the lower M10 extender(MEXD-AA). It is not recommended to connect CDR directly into the RCV sub unless it is donein the shop.

4. Coiled Tubing Drilling

4.1 Tool Details

4.1.1 CTOT-AA Orienting Tool

The orienting tool (S-281561) was originally designed by Dowell, but is now manufactured byAnadrill. This tool allows the operator to control the orientation of the BHA below it; i.e. themotor tool face. Functioning as a hydraulic ratchet, when the flow rate drops below a certainlevel, a spring loaded piston moves up and slightly right. As the pump rate is returned to normal,the spring loaded piston travels down engaging the next set of slots or grooves that rotate thesleeve (moving the lower housing in the opposite direction). Each complete cycle turns the BHA30 degrees.

Because the hydraulic piston is essentially fixed to the upper housing of the tool, the sleeverotation to the right is in effect moving the BHA below the tool to the left. This counterclockwise rotation of the BHA was designed to make use of the reactive torque from the motor tohelp overcome drag and turn the BHA. It is also assumed that the tool string above the orientingtool is restrained from rotating due to hole drag.

Be cautious of the flow rate restrictions. Any flow rate above 120 gpm could severely limit thefunction tool life. The splines of the spring loaded piston are not able to withstand the higherdrilling torque associated with 4-3/4" motors. Directional operations with motors larger than 3-1/2" are not recommended for these reasons. There are no other orienting tools on the openmarket that will fill this need.

A high torque retrofit kit is available for existing orienting tools. The modification provides threetimes more torque than the original design and will retrofit on any of the existing tools. All neworienting tools will be high torque models.

There are some areas where the natural tendency is for the tool face to roll left as drillingprogresses. In these applications, a slight tool face correction to the right is needed. With thecurrent tool, one needs to ratchet the tool face all the way around to the left to achieve the desiredchange.

Note: the standard orienting tool turns the BHA to the left. Right-handed orienting tools can beassembled with the spline mandrel and spline sleeve in the equipment list and on the MasterOrder sheet.

A service tool kit (S-281721) available through manufacturing that covers the expendablesneeded to service this tool and the drilling connector.





4.1.2 CTCT-AA Drilling Connector

The drilling connector (S-281559) is another tool originally designed by Dowell, but now offeredby Anadrill. The drilling connector is actually three tools in one. It incorporates a pull orhydraulic disconnect, flapper valves for pressure control, and a drop ball circulating sub.

It has a flow limit of 120 gpm. Any extended operations at flow rates above this level will causeerosion of the tool and severely limit the functional life. If higher flow rates are required(typically for drilling with larger BHA's) many other connectors are available on the openmarket. Some of the more common suppliers are Grifco and Petrotech. Dowell is familiar withthese alternatives.

The top sub of the drilling connector assembly is a non-rotating joint which allows for the finalfield connection of the BHA to the coiled tubing. Since coiled tubing cannot be rotated like aKelly, the non-rotating joint allows for the final make up of the BHA. This is a low torqueconnection with set screws to allow for final make up with a pipe wrench. Although it is a part ofthe drilling connector assembly, it is shown as a separate item on the BHA sketches.

A service tool kit is available through manufacturing that covers the expendables needed toservice this tool and the orienting tool.

The same CTD Support Tool Kit (S-281721) listed under the orienting tool will support theexpendables for the drilling connector also.

4.1.3 CTCT-BA Bottom-NRJ Drilling Connector

In some coiled tubing drilling applications, for pressure testing or injection, it is desired that thenon-rotating joint (NRJ) be located on the bottom of the drilling connector tool. For this reason,the Bottom-NRJ Drilling Connector Tool (S-291309) is available. This tool is very similar to theDrilling Connector tool (CTCT-AA). It incorporates the check valves, disconnect piston, andcirculating piston. However, the big difference is that the NRJ has been moved from the top ofthe tool to the bottom. The top end of the tool is a check valve housing with a 2-3/8 API Reg.Box connection. The bottom end of the tool has an NRJ connected to the 2-3/8 API Reg. Pin ofthe bottom sub. This NRJ is also 2-3/8 API Reg. Box by Pin.

4.1.4 Coiled Tubing Connector

The coiled tubing connector is merely the crossover from the coiled tubing to the drillingconnector. This tool, designed by Dowell for drilling applications, incorporates set screws tohold the connector in place on the coiled tubing.

A coiled tubing dimple tool is required to make the initial indentation pattern in the coiledtubing. Once this is done, the coiled tubing connector (or dimple connector as it is called) isplaced on the coiled tubing and the set screws torqued into place. The coiled tubing connectorand dimple installation tool will remain the responsibility of Dowell.





Again for higher flow rate or larger hole applications, there are many other styles available onthe open market. Dowell is familiar with these alternatives.

4.1.5 Other Related CTD Equipment

a) UBHO

A custom designed UBHO sub (S-277980 steel, & S-277982 non-mag) is available for smalldiameter (3-1/16") applications. It utilizes a custom key sleeve and custom Slim 1 stinger.

A custom built adjustable key sleeve (S-261388), similar to a standard design, with a custombuilt flow through stinger (S-261387) for Slim 1 is available. Again, due to the small diameters, aflow through stinger is required for the mud flow.

The adjustable key sleeve is an advantage over the fixed key because it is much moreconventional. Use of the fixed key sub caused a tool face orientation correction problem on someof the early jobs.

This new UBHO design is part of the CTD Master Order. The UBHO can be ordered in steel ornon-mag depending on your specific needs.

b) Flex NMDC

Standard non-mag collars with 3-1/16" OD for 3-3/4" hole are available. To get the proper flowvelocities around the Slim 1 tool, the ID was designed at 2-1/16". This ID allows for adequatefluid velocities (50 fps or less) up to a flow rate of 144 gpm. A custom thread profile wasrequired for the OD/ID restrictions, thus the Anadrill designed 2.590" V055 thread was used.

A bore back was put into the box end of each to accept a modified Slim 1 flow sleeve. Thissleeve will drop into the top of the NMDC and rest on a shoulder at the bottom of the bore back.The bore back is pushed deep enough to allow room above the sleeve for the swirler required forlow flow operations. The swirler must be deep enough to avoid interference with the pin of theconnection above. The modified flow sleeve and swirler are part of the Slim 1 low flow kit, S-267648.

The 15 ft length of the flex non-mags (S-277807) is a function of needing to keep the individualBHA components at 15 ft or less for handling constraints on the coiled tubing units. Two 15 ftpieces could then be used for Slim 1 only jobs. An additional 8 ft piece (S-277808) could beadded for the addition of GR. Again, the idea is to keep each component and the overall BHA asshort as possible. With this setup, the D&I package is essentially right at the connection betweenthe two 15' non-mags.





The flex profile was implemented for use in high build rate applications. This profile will allowthe BHA to be more flexible when negotiating the curves. The flex profile provides an additionalbenefit during pressure deployment. The BHA is too long to deploy in one piece. Therefore it hasto be run in the hole in several sections. The gripper rams in the BOP stack along with some slipson the working floor can be used to hold the BHA when making up the next section. The 2-7/8"flex OD on the NMDC is ideal for the gripper rams.

A Slim 1 modification which moves the D&I package to the bottom of the tool (thus the optionof ordering a non-mag UBHO sub - and non-mag motor if really necessary) is available.

The non-mags can be custom ordered to any dimension needed. Once a new operating area gainssome experience with these tools, they may want to customize their equipment set up.

c) Slim 1

The Slim 1 pulser has gone through many changes to get to the current low flow design. Thisdesign also introduces a swirler to increase the torque acquired from the fluid by the impeller.One operating parameter to pay particular attention to is the pressure threshold required to get asurvey. This pressure or flow rate threshold needs to be balanced properly with the functionalflow rate threshold of the orienting tool. The idea is to be able to get a Slim 1 survey withoutratcheting the orienting tool. The flow rate at which this is done must be given considerationprior to the job start. Many operators have used a pump test in the shop to identify the thresholdsand the corresponding flow rates.

4.1.6 Optional Tools

a) Jars

Anadrill's 3-1/16" fishing jars (#45577) have been used on some CT drilling operations. Thesejars are shorter than any of the competitor's jars in comparable sizes, but they do add over six feetof length to the BHA. This particular size of jar is not available in most locations. Using theseAnadrill FB fishing jars as drilling jars is not very common. Depending on the location, manyoperators do not require the fishing tools to be on location. Knowing where to find the toolswhen needed has been sufficient.

b) Flex Joints

Flex joints can be placed immediately above the motor to maximize the effective build rateswhen needed, as well as to minimize the affect that any bending moments from the BHA abovethe motor may have on the BUR. The effectiveness of flex joints will vary from job to job, buthave been shown to add two to four deg/100' to the build rate achieved by a given motorconfiguration. Flex joints can be run on each side of the orienting tool in high build rateapplications to attempt to isolate the orienting tool from the bending moments of the BHA bothabove and below the tool. In some previous work, the orienting tool would not function in a highbuild rate curve. The BHA had to be pulled up above the KOP to operate the orienting tool.





The high torque orienting tool will extend the operational range. These limits are a function ofthe hole size and build rate. Recommendations are included in the orienting tool operationsmanual. In general, the flex joints are not used very often, but will remain available fromAnadrill Manufacturing if needed.

c) Non-rotating Connector

The non-rotating connector, or field connection, of the drilling connector has been customizedfor use in other parts of the BHA. In some specific pressure deployment applications, there maybe a need for a non-rotating joint at some other point in the assembly. This is rare, but can bebuilt as needed. Further experience will help identify the need for this modification.

d) Float Sub

As on conventional jobs, float subs may be required above the motor. With the 3-1/16" BHA inuse with CTD operations today, one can still run a float sub using Baker 1R floats as needed. Forjobs requiring pressure deployment of the BHA, operators have typically required a sub with twofloats. A float sub that accommodates two Baker 1R floats is part of the Master Order (S-281627).

e) Fishing Tools

Fishing tools should be considered prior to the job - especially in more remote locations. Fishinghas been done successfully over the years using coiled tubing. The complications that arise aredue to the small annular clearances for overshots in some of the smaller holes, and the difficultyin trying to achieve a slow rotation of a fishing tool using a downhole motor. Most operatorshave not required the fishing tools to be on location. It has been sufficient in most applications tohave the fishing tools located for last minute call out only.





f) TIW Safety Valve

A TIW safety valve is recommended as a safety device for tripping the BHA on under-balanceddrilling applications requiring deployment of the BHA under pressure. This item is rarely usedand is only on the Master Order Form for very specific applications.

The design of the BHA and use of pressure deployment needs to be considered carefully withevery contingency thought through completely. The Dowell Project Manager is normallyresponsible for the deployment procedure and contingency plans.

5. VIPER

5.1 Highlights

VIPER is a 2 7/8 wireline steerable BHA for coiled tubing drilling and slimhole re-entryoperations for drilling wellbores from 3-1/2 to 4-3/4. It incorporates an electrical disconnect, atelemetry tool, and an orienting tool. VIPER can be used with any drilling fluid or gas and isideal for underbalanced drilling operations. The electric disconnect system is actuated from thesurface and requires a minimum 600 psi hydrostatic pressure to operate. A secondary mechanicaldisconnect is also available. The measurements provided by the telemetry tool are D&I, gammaray, external pressure, internal pressure, orienting tool position, casing joints detection, andmotor stall indicator. The orienting tool is electrically actuated from the surface and providesrotation in both directions with fine resolution of toolface. A standard wireline telemetryformatting (CTS) is used to transmit data to the surface and command the orienting tool. TheWAFE system interfaces the wireline to IDEAL/WIS and provides electrical power to the BHA.Log presentation, data storage, and orienting tool control are supported by IDEAL. IDEALinterfaces to Dowells CoilCat surface acquisition system through an ethernet link.

5.2 Details

5.2.1 Surface System

The surface system includes the IDEAL system, the WAFE system, a dummy cable (CIA-B), aUPS, and all required cables. Note that a rotary collector (COL-ZA) is needed for the CT Unit,but is considered an optional item as it may already be in place on the CTD unit.

IDEAL supports the real time display, the orienting tool control, the log presentation, thedatabase for all measurements, and VIPERScope. The IDEAL PC is connected to the WAFEthrough an Ethernet link. The surface measurements (depth, coiled tubing tension, pressure, etc.)are transmitted real time to IDEAL via the CoilCat system (Dowell surface system). The CoilCatmachine is connected to IDEAL through an Ethernet link.

The WAFE system is the acquisition front end interfacing IDEAL and the CTS telemetry. It alsoprovides the power for the BHA. The WAFE must be equipped with a CTS module (TCM) andhave minor modifications for the cable fault detection system. The system is designed to operatewith a standard heptacable 7-46, or 7-42 type, 15,000 ft maximum length. Four conductors areused for the power supply (400 VDC) and the telemetry signals, one conductor for the electricaldisconnect, and one conductor for the cable fault detection system.

The cable interface adapter, (CIA) S-281133, must be used every time the cable length is lessthan 10,000 ft.





As noted above, an explosion proof 8 ring collector COL-ZA (H709710) must be installed on thecoiled tubing reel for connection to the wireline.

5.2.2 Drilling Head (VDHA-BA)

The Drilling Head allows for the connection of the BHA to the coiled tubing (2", 2 3/8" or 2 5/8OD) and the wireline in both overbalanced and underbalanced well drilling. It includes a quickconnect, an electrical disconnect (a minimum pressure of 600 psi is needed to activate thesystem), a TIW type Ball valve and two float valves located above the electrical disconnect. TheDrilling Head can be connected directly to a other downhole tools (i.e. PowerPak motors) usingthe 2 3/8 API crossover S-280965. The Drilling head comes equipped with adapters for 2 or 2-3/8 coil tubing. It also includes the clamp assemblies for 7-46P, 7-46P-CAP, 7-42P or 7-42P-CAP wireline cable.

5.2.3 Telemetry Tool (VOEA & VDGA)

The Telemetry Tool includes the following modules :

• Telemetry/CPU: CTS telemetry and downhole bus (ISB) interface.

• Power Supply: digital and analog power supply for ISB.

• Pressure: pressure sensors*, acquisition electronics, DSP, and ISB interface.

• UDIM: D&I sensors*, acquisition electronics, DSP, and ISB interface.

• UGRM: Gamma ray detector*, acquisition electronics, microcontroller, and ISBinterface.

*Note: The calibration coefficients are stored in a EEPROM located in each module. Thesecoefficients can be downloaded directly from VIPERScope via the ISB using the VIPERScopeInterface Box S-281122.

The UDIM and UGRM are the same modules used in the SHARP tool.

5.2.4 Orienting Tool

The Orienting Tool allows orientation of the steerable motor in either direction, right or left, andcan also be used in a continuous rotation mode. It includes the following sections :

• Orienting tool electronics: acquisition, motor drive, microcontroller, and ISB interface.

• Motor assembly: brushless DC motor, brake, 4-stage gearbox.

• Final stage assembly: one stage gear box, radial/thrust bearings, rotary seals.





5.2.5 PowerPak

The VIPER BHA is designed to be run with a 2 7/8, 3-1/8, 3-1/2 and 3-3/4 PowerPakmotors. The PowerPak must be equipped with a non-magnetic power section in order not toperturb the magnetic measurements. Care must be taken when running with heavy mud weightsnot to exceed 1000 ft-lb. stall torque on the motor as the motor is directly coupled to the geartrain in the orienting tool.

The non magnetic float sub S-291547 can be connected between the orienting tool and the powersection to allow a two part deployment into a live well (see Dowell Coiled Tubing OperatorsManual). Any sub located between the power section and the orienting tool must be nonmagnetic.

VIPER is designed to operate in 100°/100 ft radius (DLS). Anytime the dog leg severity is toexceed 30°/100 ft, the Articulated Assembly is to be run between the orienting tool (VOMA) andPowerPak. This knuckle joint reduces the bending stresses on the gearbox.

5.2.7 Underbalanced Drilling

Special precautions for deployment must be taken when VIPER is run in an underbalanced well.The Drilling Head is the primary well control valve during deployment of the BHA into and outof the well. Well control is critical in live wells - those that have well head pressure duringdrilling and deployment. Two versions of the Drilling Head exist:

• VDHA-AA (S-): Can be used only in dead wells situations (no wellhead pressure whenpumps are off) and where the entire BHA can be deployed in a single stage. This tool hasbeen obsoleted by VDHA-BA, cannot be ordered and is supported with spare parts only.

• VDHA-BA (S-291815): Must be used if single stage deployment cannot be accomplished orin live wells (wellhead pressure at all times).

In either case, a float valve sub (B034673) is to be run between the PowerPak motor and theVIPER BHA for added safety during deployment.

When the use of the articulation joint is not desired, a cross-over float sub (S-291547) is alsoavailable to connect the orienting tool to the PowerPak stator. This float sub also holds the floatvalves and will allow for a two-stage deployment into a live well (see Dowell Coiled TubingOperators Manual). This sub is non-magnetic so as not to perturb the magnetic measurements.

5.2.8 Multi-cycle Disconnect (S-291580)

The VIPER system has the option to run an additional disconnect between the VIPER tool andthe PowerPak motor. This option is to reduce risks associated with lost in hole cost.





The 3.06 multi-cycle disconnect (MCD) is designed for coiled tubing operations where a reliable,variable set, disconnect is desirable. This particular model is non-magnetic for close operationwith MWD tools such as VIPER. The MCD allows for a controlled setting of the tensile weakpoint simply by machining the OD to the proper diameter.

The tool consists of a J-slot which is actuated by pickup/slack-off of the drill string. This motion(via the J) unscrews a nut with very large threads. The tool is oil filled and the mechanism isalways in oil. The tool has a weak point sleeve which must be pulled apart before the J-slotmechanism is engaged. Once the weak point is pulled apart, the disconnect process starts. After4-1/2 pickup/slack-off cycles a flow port is opened between the ID and annulus (when offbottom). The circulation port is a tattle-tale device to signal proper operation or give notice ofpremature disconnect. After 7-1/2 cycles the tool will disconnect. A 3 GS fishing neck is left inthe hole facing upward.

The tool allows for a full tensile pull on the assembly once the weak point has been broken. Infact a full tensile pull can be performed on every up stroke except for the last cycle (sixth stroke),This stroke is limited to 20,000 lb. pull because of the threads on the releasing nut are not fullyengaged.

The length of the tool is 39.4 inches with a 2-3/8 API Reg. connection on top and bottom: Boxup, pin down. The tensile sleeves can be set from 10,000 to 40,000 lb. The proper setting for aparticular well is determined by the amount of predicted pull at TD. These calculations are doneusing the Dowell CoilCade system.

5.2.9 Logging Adapter (S-291881)

The logging adapter is an optional item that allows the operator to quickly and efficiently laydown the VIPER BHA and pick up an openhole wireline logging tool without having to re-headthe coil tubing. The logging adapter incorporates the quick connect and a male TLC connector toadapt directly to the upper end of the VIPER drilling head. The assembly also has a TIW typeBall Valve, two float valves and the Multi-cycle disconnect incorporated into the tool. The tooladapts directly to the 2 ½-in. SlimAccess tools or 2-3/4 and 3-3/8 logging tools with crossoverssupplied by W&T.

6. Inclination-at-Bit (IAB) Tool

6.1 Highlights

The fact that current MWD technology is generally located 40 - 60 feet from the bit in a bottom-hole assembly makes drilling a lot like driving a bus from the back seat. Undulation andtortuosity result from under- and over-correction when extrapolating inclination measurementsfrom the MWD collar to the bit. Measuring inclination directly at the bit prevents theseproblems. Hence, SPC's Advanced Drilling Systems department has developed a bit inclinationtool.

The Inclination-at-Bit equipment is used in conjunction with MWD to provide the At-bitInclination Measurement (AIM) service. The current system operates in the 4-3/4, 6-3/4", 8,and 9-5/8 tool sizes. The 4-3/4 (IAB4I-AB, S-292222) and 6-3/4" (IAB6I-AA, S-292333) IABtools are operated as an integral part of an A475 and A675 PowerPak Drilling Motor,respectively. Figure 6-1 illustrates a 4-3/4 PowerPak drilling motor assembly including theIAB4 transmitter. The 8 (IAB8S-AA, S-292800) and 9-5/8 (IAB9S-AA, S-292900) IAB toolsare stand alone subs, which are used in conjunction with A800 and A958 PowerPak DrillingMotors, respectively. Figure 6-2 illustrates a 9-5/8 PowerPak drilling motor with the AIM9assembled.

Figure 6-1 IAB4/A475 PowerPak Motor Schematic

Figure 6-2 IAB9/A958 PowerPak Motor Schematic





The IAB tools measure inclination from a position 12 inches behind the bit for the 4-3/4"tool, 15inches behind the bit for the 6-3/4" tool , 39 inches behind the bit for the 8 tool, and 29 inchesbehind the bit for the 9-5/8 tool. The tools then transmit this data to the MWD system viaelectromagnetic telemetry. The current MWD receiver systems for the 4-3/4" system are theIMPulse tool (IMPA-BA, S-285907) and the ISR4 (ISR4-AB, S-292444) which works inconjunction with the SHARP/SlimPulse system. The ISR4 also contains an annular pressuremeasurement. The current MWD receiver systems for the 6-3/4" system are the ARC6 tool(ARC6A-AA, T1004000) and the UIT6 tool (UIT6-AA, T1032000) which is currently in fieldtest. The UIT6 also has two-way transmission capabilities. The current MWD receiver systemfor the 8 system is the ARC8 tool (ARC8A-AA, T1004100). The current MWD receiver systemfor the 9-5/8 system is the ARC9 tool (ARC9A-AA, T1004160). Additionally there is a new 6-5/8 receiver sub (ASP6) in process in engineering designed to work with the Slimpulse system.This sub should be available for field test in early 2001.

The inclination measurement is performed by a single-axis, Q-flex accelerometer mounted alongthe center axis of the IAB Drive Shaft. This is the same proven accelerometer used in our MWDtools. Figure 6-3 shows a cut-away schematic of the 4-3/4 IAB tool and Figure 6-4 shows a cut-away schematic of the 9-5/8 IAB sub. The IAB tool also includes temperature and shockauxiliary measurements. These measurements are not typically transmitted in real time due to thelimited telemetry rate.

The IAB uses Induction Electromagnetic Transmission (IMAG) as opposed to the EMAGtelemetry used in the GeoSteering tool. IMAG telemetry is an improvement over EMAG. Thereare no limitations in high-resistivity formations, high contrasting formation, or in ANY mud type(OBM, foam, or salt-saturated mud). It does, however, have range limitations in highly-conductive formations, i.e., at 0.2 Ω-m. transmission is approximately 35 ft for the 4-3/4" tool,48 ft for the 6-3/4", and 63 ft. for the 8 and 9-5/8 tools. This can limit the placement of theReceiver Sub in the BHA. For further information consult the IAB UOP or Maintenance Manual.

The IAB tools are battery powered. The batteries are currently annular in assembly and are ratedfor 250 hours of life. Additionally, the IAB6 batteries are a rig-replaceable split pack design. TheIAB8 and IAB9 tools use the same annular battery, which is rig-replaceable as well. The IAB4and IAB6 tools include a Rotating Near-Bit Stabilizer (RNBS) that also acts as the batterypressure housing. The IAB8 and IAB9 subs also include a RNBS, but for these tools thestandard PowerPak 8 and 9-5/8 RNBSs can be used. Similar to PowerPak RNBS stabilizers,the RNBS on the IAB acts to improve rate-of-penetration and weight transfer. The IAB stabilizeris present to insure the increased side forces generated by the additional offset length does notcause premature bearing failure. The stabilizer also acts to stiffen the IAB assembly for theIAB4 and IAB6 tools. The IAB stabilizer must be run 1/8-in. under bit gauge or less.

6.1.2 AIM Receivers

For all AIM systems, there is a receiver built into different MWD platforms. For the IAB4, thereceiver is built into the IMPulse tool. For the IAB6, IAB8 and IAB9 tools the receiver is builtinto the ARC6, ARC8, and ARC9 tools respectively. For specifications on these tools see theirrespective equipment guidelines. Additionally there are two receivers built by the IAB group.They are the ISR4, which works with the SHARP/Slimpulse system in the 4-3/4tool size, and the UIT6 which is a stand alone sub with LTB connections which works in the 6-5/8 tool size. In early 2001 a new receiver, the ASP6, will be released for field testing whichworks with the Slimpulse in the 6-5/8 tool size.

Refer to the individual tool sections for specs on ARC6, 8, 9 and IMPulse Receivers.

7. Drilling Tools

7.1 Earthquaker Jars

The Earthquaker mechanical drilling jars hit in both directions with up to 90 tons of force, andthey can be cocked and tripped repeatedly to free the string without affecting their preset releasepoint. They are insensitive to torque and therefore will not affect hole orientation while deviatingthe well.

The unique preset tripping mechanism is fully mechanical. Neither right not left hand torque inthe string changes the tripping loads, and no torque is needed to trip the jar at its preset loads.Earthquaker jars can be placed below the neutral point to provide for closer placement topotential sticking points and more flexibility in BHA design. In addition, Anadrill offers the CAPComputerized Analysis and Placement program for drilling jars which recommends preciselywhere to place jars for maximum effectiveness.

Upward and downward tripping forces are independently adjustable to match drilling conditions.The force for each direction can be set from as low as 10,000 lbf to as high as 180,000 lbf,depending on jar size, while the jar is in the rotary table. An Earthquaker jar can take the abuseof long periods of continuous drilling because of innovative design, simple construction andcareful assembly. All working parts are enclosed in oil, so foreign materials in mud do not causewear or a malfunction. A pressure-compensating piston minimizes pressure differential on theseals.

Torque does not affect jar load settings.

Fully mechanical tripping mechanism with working parts is sealed in oil for reliability.

Accurate control of jarring action eliminates guesswork of jar operation.

Tripping forces of up to 180,000 lbf are available for maximum jarring impact.

Jar can be run in compression below the neutral point for jarring action closer to the bit.

All sizes except the 6 7/8" are available in the CR (concentric ring) tripping mechanismdesign that is easier to maintain and has fewer parts. A conversion kit for 4 3/4" x 1 7/8 isavailable to convert to the 4 3/4" x 2 CR design.

Earthquakers must always be with Flex Joints, though they can be ordered without them.Safety collars are optional and need not be used due to the inherent safety of the mechanicaltripping mechanism.

CAP analysis ensures proper placement for optimum effect.

7.2 Hydraquaker Jars

Thirty years' experience in hydraulic jar design are seen in Anadrill's simple, reliableHYDRAQUAKER drilling jar. The pressure relief assembly prevents the jar from beingoverpulled and circumvents costly damage and loss of jarring ability. The large surface area ofthe seal allows the tool to be run in compression. These compression or "below neutral point"placements are complemented with Anadrill's CAP program.

Large ID's allow passage of freepoint equipment.

Design allows jar to be run in compression below the neutral point for jarring actioncloser to the bit.

CAP analysis ensures proper placement for optimum hitting.

Full 8 inch up and down free stroke provides maximum impact.

Pressure relief assembly eliminates overpull limitations in 4 3/4" and 6 1/2" jars.

Currently, operations limitations exist only in high chloride content drilling fluids which tend topit the plating where the seals are. A set of sacrificial aluminum sleeves can be used to protectthe internal plating from pitting corrosion.

The 4 3/4" and 6 1/2" are commercialized

Hydraquakers must always be run with Flex Joints, though they can be ordered without them.Safety collars are mandatory and must be used to keep the jar from closing when racked back.

7.4.3 Nitrogen Jar Boosters

The nitrogen jar booster increases the jar impact on the fish. No matter how deep the well, the jarbooster provides a powerful spring force between the fishing string and hydraulic jars, givingmaximum impact by accelerating the up upward movement of the drill collars. The system hasseveral advantages:

Nitrogen gas eliminates fluid damping inefficiency in liquid-type devices.

One-piece mandrel and bottom connections eliminate accidental backoff.

Specially designed seal assemblies and antiextrusion devices prevent gas leakage.

High-quality materials and specially designed valving system for charging and bleeding offpressure provide maximum safety.

Maximum stroke provided every time by elimination of junk traps.

Increases jar efficiency and reduces rig fishing time.

Eliminates the pipe drag problem

Overcomes shallow-well problems in fishing operations

Serves as a shock absorber to the rig

Provides greater impact and safer operations through use of inert nitrogen gas.

Maintains boosting power even under the toughest well conditions.

Lessens chances of differential sticking on drillstem tests.

Pull on fishing string compresses nitrogen gas in booster. The compressed gas acts as a powerful compressed spring.The hydraulic jar trips and the “hammer” begins its upward movement toward the “anvil.”The nitrogen gas “spring” is released, driving the drill collars upward at an accelerated rate of speed.Hydraulic jar hits with maximum impact to release fish, a result of the high-velocity energy generated by the mass and velocity of the upward-moving drill collars.
