JFEBEAR-TP-M-001 (REV.2) Page-1

PREFACE

The JFEBEAR connection has been developed and patented by JFE STEELCORPORATION.

Connections are manufactured by JFE STEEL CORPORATION or its

authorized MANUFACTURING LICENSEES.

The recommendations and illustrations in this document were developedfrom the offshore and onshore experience of running crews and advicereceived from Operators and their contractors.

Please be aware of the useful guidelines and recommendations in thisdocument and apply them when necessary.

1 PREPARATIONS BEFORE RUNNING

1.1 Handle Pipes Carefully Use pipe body slings in preference to end hooks. End hooks are only permissible with the correct type of thread

protector.

1.2 Racking Pipe Rack pipe in level horizontal layers, at least 8" (200mm) above the

ground surface. Separate layers of pipe with at least three wooden slats placed

perpendicular to pipe at each end and in the middle. Slats should

at least be 4" x 2" (100mm x 50mm). Do not stack pipe more than 7' (2.1meters) high.

Take care not to crush bottom layers of pipe and ENSURE RACKIS SAFELY SECURED.

1.3 Segregate Unusable Pipe Remove rust, scale, dirt and debris from inside and outside

surfaces. Remove any dented, bent or otherwise damaged pipe for possible

repair.

1.4 Clean and Inspect Connections

Remove all lubricants or compound with liquid solvents (not dieselfuel)

Use non-metallic brushes to remove adhered solids. Segregate all rejected thread/seals/tubes. Minor damage on pin & box connection may be repaired in

accordance with JFEBEAR-TP-M-101, prior to running. THOROUGHLY DRY THREADS AND SEAL SURFACES. If pipe is to be moved from rig site back into storage then re-apply

an acceptable thread compound thinly and evenly on all threadand seal surfaces. Use a clean uncontaminated compound andapply with a clean non-metallic brush. Avoid excessive amounts of

thread compound. For long term storage, use a suitable storage compound such as

Kendex for both pins and boxes.

Note: API thread compounds may not be suitable due to "drying out"and reduced corrosion resistance.

Replace CLEAN AND DRY pin thread protectors.Note: Application of thread or storage-compound to connectionseals and thread surfaces is recommended if there are anysignificant delays in pipe running. Clean and dry thread protectors

should also be re-fitted.

1.5 Make-up Loss The effective length of each tube is the overall length minus the

make-up loss. The make-up loss is the pin length listed in the Table 1.

2 THREAD PROTECTORS

2.1 Always Protect Threads and Seals Ensure approved thread protectors are installed at the mill and at

the storage point. Use only clean and undamaged protectors.

Use only clean non-contaminated thread or storage compoundapplied thinly and evenly over entire thread/seal area.

Assemble protector to hand tight position. Insert suitable torque bar in the grooves provided and tighten.

Note: Do not hammer bar or protector to tighten.

2.2 Protector Selection (Refer to JFEBEAR-TP-N-101) Approved protectors may be of metal or molded plastic

construction. Premium connections require adequate protection in the threaded

area, particularly at the extremity of the pin seal. A minimum of

3/4" (19mm) is recommended between the bottom of the torquebar groove and the position of the pin seal extremity when theprotector is fully tightened.

Protectors should be manufactured to allow an even thickness ofthread compound to cover threads and seal when in the fullymade-up position.

Protectors should be manufactured for optimum performance in a

temperature range of -40F to +110F (-40C to +45C).

3 RUNNING

3.1 Check Torque Values ALWAYS check with Manufacturers Authorized Representative to

determine the latest recommended make-up torque values for theJFEBEAR connection.

Note: Recommended maximum calibration interval for all Make upequipment should be no more than 6 months.

3.2 Place Pipe on Racks (see also section 1.1 and 1.2) Segregate pipe that has been damaged or pipe which is not fit for

purpose.

Unless previously done, clean and inspect all connections perguidelines stated in section 1.4.

When ready to commence running, ensure clean and dry pinthread protectors are in place to protect threads and seals whilepipe is being lifted through V door.

3.3 Handling Pipes Handle pipes as described in section 1.1. Use only clean and undamaged handling plugs. Make-up hand

tight only. Do not use a cheater bar.

With collar or slip type elevators, ensure that elevator diametersare compatible with coupling and pipe body diameters.

If drifting is required, carefully remove closed end thread protector,replace with a clean open end thread protector and drift tube withnon-metallic Teflon/Nylon type "rabbit" of correct drift diameter.(Metal drifts are not recommended unless the ends are taperedsufficiently to avoid torque shoulder contact.)

Lift pipe to vertical pre-stab position above the rotary table.

Remove pin thread protector and apply clean uncontaminatedapproved thread compound with friction factor of 1.0. Use non-metallic brush. If compound friction factor is not equal to 1.0, as isoften the case with the environmentally friendly compounds, referto Manufacturers Authorized Representative for revised torquefigures.Note: Hold pipe away from open coupling to avoid debris

contamination of open box.

3.4 Coupling Threads and Seals

Ensure Coupling thread and seal areas are covered with a lightcoat of recommended thread compound. Prior to stabbing, fit a clean properly sized STABBING GUIDE over

the coupling and securely fasten. Align the pipe and carefully lower pin through the stabbing guide

into the coupling. Rotate tube BY HAND OR WITH STRAP WRENCH until threads

are fully engaged to the hand tight position. With power tongs rotate tube until seal engagement and desired

final torque is achieved. Final make-up torque should not exceed6 RPM.

(COMPUTER CONTROLLED MAKE-UP TORQUE TURNEQUIPMENT IS RECOMMENDED)

3.5 Make-up Acceptance and Rejection For an acceptable make-up both the total torque and shoulder

torque requirements must be satisfied following guideline.Final torque shall be meet between specified minimum torqueand maximum torque.Shoulder torque shall not be exceeded specified maximumshoulder torque.

Connections which do not meet the make-up requirements shouldbe broken out and should be inspected in accordance with

JFEBEAR-TP-M-101 prior to re-makeup.

3.6 Lowering Tubing String Lower entire tubing string by one joint and proceed to next

connection. For subsequent connections follow make-upprocedures 3.1 through 3.5.

4. BREAK-OUT AND LAY DOWN PROCEDURES

4.1 Pulling of Pipe Pulling of pipe should be conducted with care to avoid damage to

threads and seal areas.

Ensure that proper alignment of blocks over the well is achievedand that derrick-man is aligning each joint over the well duringbreakout. Misalignment may result in connection thread galling.

Take care not to over rotate during back-out so pin connectiondoes not "drop" back into coupling.

Apply tension to the joint (or stand) being backed out. The appliedload should approximately equal the weight of the joint. Use aweight compensator where possible.

During stabbing, use a stabbing guide to avoid pin threads or sealsstriking the coupling.

Re-apply both pin and coupling thread protectors immediately after

pin/coupling disengagement. Pulling in singles is recommended. If "stood back" in the derrick, ensure the pin end protectors are

fitted and "stand" is seated on a wooden or similar non-metallicsurface.

4.2 Rotation of Connection Place power tong on the top joint with the back-up tong on lower

half of coupling to avoid unnecessary gripping pressure on theconnection end to be broken-out.

Set tong rotation for break-out and ensure single joint or standweight is taken up by elevators. Break-out the connection withpower tongs, approximately 1 turn for tubing and 2 turns for casing.

After breakout, remove power tongs and rotate connection out byhand or strap wrench.

Place an appropriately sized STABBING GUIDE over the couplingand lift top joint (stand) clear of coupling and stabbing guide.

Install a CLEAN pin protector and either lay the joint down or standinto derrick on a clean non-metallic surface. If laying down pipeonto pipe deck use slats.

Install a CLEAN coupling protector into the coupling.

Lift string to next breakout joint and repeat steps as per section 4.2.

5. RE-RUNNING JFEBEAR CONNECTIONS

Instructions for re-running joints are exactly same as for newconnections and the same make-up torque values are applied.

Prior to re-running each connection should be inspected inaccordance with JFEBEAR-TP-M-101.

6. HIGH CHROME TUBULAR STORAGE RECOMMENDATIONS

6.1 Removing Tubular Goods Where possible, remove the tubular goods from their export

packing IMMEDIATELY upon receipt and store them indoors in adry atmosphere.

6.2 Inspect Tubulars Periodically Inspect the tubular periodically, i.e., every one to three months

depending on atmospheric conditions. Routine inspection shouldinclude:O.D. check for discoloring or pittingI.D. check for discoloring or pitting

Remove thread protectors and check condition of connections andstorage compound.

Replace connection storage compound as required. Apply evenlyto thread and seal areas.

6.3 For Long Term Storage For periods of storage longer than two months a connection

storage compound shall be used.

Note: API THREAD COMPOUNDS ARE NOT RECOMMENDED FORUSE AS A LONG TERM STORAGE COMPOUNDS.

6.4 Out Door Storage If out door storage is the only option, the following additional

procedures are recommended. Protect from rain and spray with tarpaulins or plastic covering.

Sweating / condensation may occur if there is insufficient aircirculation.

Avoid stagnant water or moisture. Every thirty days, roll tubes toensure that no moisture remains trapped between stripping andpipe OD. This also allows any trapped moisture to dry. It isrecommended to use plastic stripping or zinc paint on wood stripsto avoid direct contact between tubulars and wood.

Store tubular with one end elevated to allow condensation or othertrapped water to drain from tube I.D.

6.5 Warning Plate

Refer to the "WARNING PLATE" attached to the export packagefor additional information.

6.6 Storage Following Pulling (Short Term or Long Term) Special attention must be given to high chrome steel products

when removed from well due to the materials pitting susceptibilitycaused by Chlorides in an oxygen rich environment.

Immediately upon removing tubulars from well, they should beflushed with fresh water and stored with one end elevated, to allowcondensation or other trapped water to drain from tube I.D.

After drainage is completed the connections should be cleaned,dried and inspected. If repairs are required it should be performedin conjunction with JFEBEAR-TP-M-101. Repaired connectionsshould be protected using appropriate storage compound. Re-fitclean and dry thread protectors.

Note: Above steps are applicable if pipe is to be re-run within veryshort period of time, such as 12 ~ 72 hours.

For longer periods (1 week to 4 weeks), the same applies with theexception that water soluble corrosion inhibitor for Brine Solutionsshould be sprayed on O.D. & I.D. of pipe after drainage is complete.Note: One such product is named: Aqua-Cure 690 and is suppliedby Oil Center Research.

For longer term storage greater than 1 month, it is recommendedto follow the same process with the exception that external pipecoating, namely clear varnish and internal pipe coating, namelymineral oil should be applied.

7. HIGH CHROME STEEL SPECIAL HANDLING PRECAUTIONS

Handle joints one at a time using nylon slings. Avoid joints contacting each other, i.e. "banging together" in order to

prevent local surface hardened spots which may lead to corrosion. Ensure pipe racks and pick-up/lay-down equipment is sufficiently padded

to help prevent unnecessary contact between joints and other steelcomponents.

8. HIGH CHROME STEEL RUNNING PROCEDURES

8.1 Running of High Chrome Steel JFEBEAR Connections Running of high chrome steel with JFEBEAR connections should

be handled with the following extra precautions taken. Single joint compensators are recommended. Low stress dot dies or other non-marking systems in tongs,

elevators and slips are the preferred method. Non-directional, fine

tooth, low stress dies with 360contacts are also acceptable.

Rotate tube by hand with strap wrench until threads are fullyengaged. With power tongs, rotate tube to final torque notexceeding 6 rpm.

9. HIGH CHROME STEEL RE-RUNNING

10. SPECIAL RECOMMENDATION FOR SOUR SERVICE (H2S)

10.1 Hard Spots NEVER use pipe on which hard spots have developed from the

use of direct flame heating, welding or impact damage.

10.2 Avoid DamageAvoid damage which may result in residual stress to effected area.For that reason, DO NOT: Cold-straighten even slightly-deformed pipe. Use pipe or couplings showing sharp edged slip or tong marks. Hammer pipe or couplings. Compress or deform pipe in the slips. Use pipe exhibiting excessive out of roundness. Exceed recommended make-up torque. Apply loads in excess of performance capabilities. Permit excessive bending of the string when the load is close to

elastic limit of the material. Improvise by using items of different steel strength and quality from

those programmed.
