ILLPIPEProper break-in is probably the most important factor

affecting the life of the tool joint connection. Here aresome recommendations to follow:

1. Proper make-up torque is determined by theconnection type, size, OD and ID and may befound in torque tables.

2. Make up connections slowly, preferably usingchain tongs. (High speed kelly spinners or thespinning chain used on initial make-up cancause galling of the threads).

3. Tong them up to the predetermined torque usinga recently calibrated torque gauge to measurethe required line-pull.Note: Monitor breakout torque. It should be

less than or no greater than make-uptorque. If it is greater, the connectionshould be cleaned, inspected andrepaired, before it is made up again.

4. Breakout, visually inspect, redope and make uptwo more times before running in hole. Alwaysuse backup tongs to make and break connec-tions.

5. Stagger breaks on each trip so that each con-nection can be checked, redoped and made upevery second or third trip, depending on thelength of drill pipe and size of rig.

A new string of drill pipe deserves good surface han-dling equipment and tools. Check slips and masterbushings before damage occurs to the tube. (See theIADC Drilling Manual for correct measurements).Do not stop the downward movement of the drill stemwith the slips. This can cause crushing or neckingdown of the drill pipe tube. The drill pipe can also bedamaged by allowing the slips to ride the pipe on tripsout of the hole.Good rig practices will help eliminate time consumingtrips in the future, looking for washouts or fishing fordrill pipe lost in the hole. For more information refer tothe IADC Drilling Manual.

Note: 1. The use of outside diameters (OD) smaller than those listed in the table may be acceptable on Slim Hole (S.H.) tool joints due to special service requirements.

2. Make-up torque values may be lower than those published in API RP 7G LatestEdition. The make-up values are lower due to the combined torsional and tensile loads found in service conditions.

Types of Grant Prideco DoubleShoulder Connections

There are three types of double shoulder connectionsoffered by Grant Prideco.

HI TORQUE (HT) First generation double shoul-der connection providing approximately 40% moretorque capacity than API connections of equivalentdimensions. Not interchangeable with API connec-tions.

eXtreme Torque (XT ) Second generation doubleshoulder connection providing approximately 70%more torque capacity than API connections of equiv-alent dimensions. Not interchangeable with APIconnections. Two primary differences exist betweenHT and XT connections: 1) XT has a flatter taperand 2) XT has increased thread root radii.

o eXtreme Torque with Metal-To-Metal Seal (XT-M) Industry first gas tight pressure rated rotaryshoulder connection achieved through a 15 metal-to-metal (M-T-M) seal on the pin nose. Providestorque capacity similar to that of XT connections.Not interchangeable with API connections.

Grant Prideco Double Shoulder (GPDS) Double shoulder connection which is interchange-able with API connections and provides 20-50%more torque capacity than API connections ofequivalent dimensions.

The below figure illustrates the taper difference betweenHT and XT connections.

Tool Joint Break-inMost drill pipe connections are broken-in during manu-facture. The following break-in procedure is recom-mended for connections which have not been broken-induring manufacture.Step 1: Make the joints up to the maximum recom-

mended make-up torque, and then breakthem out. If the break-out torque is lessthan the make-up torque, the joints do nothave to be separated.

Step 2: Make the joints up again to the samemake-up torque and break them out.Separate the pin and box and reapplythread compound.

Step 3: Make the joints up again to the same make-up torque and they are ready for service.

Note: The break-out torque should be less thanthe make-up torque. If the break-out torqueis more than the make-up torque, separatethe joints and inspect them for damage.

Picking Up Pipe with Double ShoulderConnections for the First Time Visually examine the thread protectors for damage

such as dents or crushing. If any thread protectors aredamaged, inspect the threads on that joint for dam-age.

If the joints were shipped to the rig with rust preventiveon the threads, it must be removed. Use soap andwater, steam or a vapor degreasing solvent such asVarsol. No residue should remain on the threads aftercleaning.

If the joints were shipped to the rig with thread com-pound, it is not necessary to remove the thread com-pound unless there is a problem suspected.

Inspect the threads for damage or for foreign material. Before the joints are put in service, the threads, the pri-

mary make-up shoulders and secondary make-upshoulders must be coated with a good quality rotaryshouldered connection thread compound.

The following sections provide general guidelines for runningand handling double shoulder connections. Connection-spe-cific running and handling procedures are available direct fromGrant Prideco and can be downloaded fromwww.grantprideco.com.

18

Special Considerations When RunningXT and XT-M Connections

Check to ensure the counterbalance on the topdrive is working properly and provides a minimumamount of weight applied to the connection duringmake-up.

Ensure the bore through the top drive bell stabbingguide (top drive flipper) is no more than 1/2" largerin diameter than the box tool joint diameter.

Because of the flatter taper, XT and XT-M pins donot stab as deeply into the box as do HT, GPDSand API connections. Alignment of the pin to thebox when stabbing and spinning up is more criticalfor XT and XT-M connections. A stabbing guide isrequired when running XT and XT-M connections,and alignment should be verified before spinningup.

Proper alignment, along with slow initial make-up ofthe starting threads, is necessary with XT and XT-Mconnections. Use chain tongs or slow speed spin-ners when spinning in the starting threads. High-speed spinners may be used after the startingthreads are engaged.

Minor thread damage may occur within the startingthreads. This is not detrimental to the connectionand should be removed with a soft grinding wheelor a file.

19

Application of Thread Compound toDouble Shoulder Connections All contacting surfaces, the threads, the primary

shoulders, secondary shoulders and 15 M-T-M seal(XT-M), must be coated with a good quality rotaryshoulder connection thread compound. Copper-based thread compounds are recommended.

Some drilling fluids or drilling fluid additives mayaffect the frictional properties of the tool joint andthread compound. If this is the case, rinse the drillingfluid off the connections before applying thread com-pound.

Remove drilling fluid from the secondary shoulderand 15 M-T-M seal (XT-M) of the box before makingup the connection for the trip in the hole. Trappeddrilling fluid can promote corrosion of the secondaryshoulders.

Racking the pipe will wipe thread compound off thepin nose. If pins are doped coming out of the hole,reapply compound to the secondary shoulder beforethe connections are made up.

NOTE: For XT-M connections, localized corrosion or pittingmay occur on the 15 M-T-M seal if racked back withoutthread compound applied to it. This is more common withcompletion fluids than common drilling fluids. Apply a liber-al and even coat of quality thread compound to the 15 sealwhen racking back XT-M connections.

Tonging, Proper Gripping of the BoxDuring Make-up Tongs should be placed at least 2 inches from the

make-up shoulder on XT boxes size 46 and greater,all HT and all XT-M boxes. These are considered"long" double shoulder connections. This is notrequired for XT boxes less than 46 and all GPDSboxes.

The threads of a long double shoulder box are about1-1/2 inches further away from the makeup shoulderthan the threads of an API box. Tongs or top drivetorque wrenches should engage these long doubleshoulder boxes at the same location in relation to thethreads that they would engage an API joint.

On the Varco BJ PH85 pipe handler torque wrench,this can be accomplished by decreasing the length ofthe saver sub from 7 inches to 5-1/2 inches. This willput the tong dies 2 inches from the box make-upshoulder.

Back-up tongs should always be used

Alignment when Making upConnections Galling and other damage can occur during stab-

bing and spinning connections up. A stand of pipe can weigh between 1,500 lbs and

2,300 lbs. At initial contact, the weight could be supported by the sharp edge of one thread againstthe flank of the mating thread. This can cause highcontact stresses and wipe the thread compound off.

Slight misalignment of the pin and box can cause further increases in the stresses when spinning up.

The whipping action of spinning pipe can causehigh loads on threads.

NOTE: Alignment of the pin to the box when stab-bing and spinning up is more critical for XT andXT-M connections. A stabbing guide is requiredwhen running XT and XT-M connections and align-ment should be verified before spinning up.

Box

Pin

Contact of sharp edge ofpin thread on box flank

Tripping Alternate breaks when tripping so that each joint

will be broken-out every third trip. Monitor break-out torque. The break-out torque should be less than the make-

up torque. High break-out torque is an indication ofdownhole make-up or thread damage.

Do not let the end of the pin strike the box make-upshoulder when stabbing the pin in the box.Stabbing guides are required for XT and XT-M con-nections and recommended for HT and GPDSconnections.

23

Standing Pipe Back Using normal drill pipe care and handling practices,

no special care is required to protect the pin nosewhen standing the pipe back. The pin nose is not aseal. Minor damage to the pin nose from standingthe pipe back does not affect the connections per-formance.

It is not necessary to use thread protectors whenstanding the pipe back.

Do not use pressed steel thread protectors whenstanding the pipe back. They could allow theweight of the stand to be supported by the primarymake-up shoulder of the connection on the sharpedge of the thread protectors.

Apply a liberal and even coat of quality thread com-pound to the 15 M-T-M seal when racking backXT-M connections.

Sharp edge of thread protectorcan damageshoulder.

24

Downhole Make-up Downhole make-up can be detected by high break-

out torque. The break-out torque should be less thanthe make-up torque.

If downhole make-up is suspected, punch mark thepin and box next to the make-up shoulders when trip-ping into the hole (after the connection is made up).

If downhole make-up occurs, the position of thepunch marks will change.

Downhole make-up can cause Compressed box counterbores Compressed pin noses

Punch marks

Apply punch marks in linewith hardness flat to makethem easier to find.

25

Make-up Shoulder and Bevel Diameter The primary make-up shoulders provide the seal for

the connection (HT, XT and GPDS). For XT-M,the primary seal is the 15 M-T-M seal and the back-up seal is the primary make-up shoulder.

The primary make-up shoulders and 15 M-T-M seal(XT-M) should be inspected frequently using currentGrant Prideco Field Inspection Procedures for theapplicable connection type.

Proper operation and correct shoulder loads dependon the pin length and box depth of double shoulderconnections being within specifications. The pinlength and box depth are shown on the FieldInspection Drawing for the particular size and typeconnection.

No more than 1/32 inch should be removed fromeither the primary or secondary make-up shoulder atany one refacing. No more than 1/16 inch cumula-tively should be removed from either the primary orsecondary make-up shoulder. The correct pin lengthand box depth must be maintained when resurfacingmake-up shoulders.

The Grant Prideco benchmark is a reference forchecking how much material has been removedfrom make-up shoulders.

The surface finish of the primary make-up shouldershould be 150 RMS or less.

When Grant Prideco double shoulder connectionsare refaced, the bevel does not need to be rema-chined.

The following sections provide information and general guide-lines regarding the field inspection of Grant Prideco doubleshoulder connections and are not intended to replace GrantPrideco Field Inspection Procedures and Drawings.

Connection type-specific Field Inspection Procedures andconnection type and size-specific Field Inspection Drawingsare available direct from Grant Prideco and can be down-loaded from www.grantprideco.com.

27

Checking Pin Length The pin length can be checked with a dial indicator

or depth micrometers. If the pin length is short by1/32 inch or less, the pin can be repaired by resur-facing the primary shoulder.

If the pin length is short by more than 1/32 inch, thepin must be recut.

If the pin length is too long by 1/32 inch or less, thepin can be repaired by resurfacing the pin nose.

If the pin length is too long by more than1/32 inch,the pin must be recut.

A Go/No Go gauge can be provided by Grant Prideco tofield check double shoulder connections primary shoul-der to secondary shoulder pin length and box depth. Thegauge does not provide dimensional information on thepin length or box depth.

If the pin nose does not contact the gauge when usedas shown in the figure, the length should be inspectedwith measuring instruments that determine the actualdistance between the shoulders.

28

Checking Box Depth The box depth can be checked with a dial indicator

or depth micrometers. If the box depth is short by1/32 inch or less, the box can be repaired by resur-facing the secondary shoulder.

If the box depth is short by more than 1/32 inch, thebox must be recut.

If the box depth is too long by 1/32 inch or less, thebox can be repaired by resurfacing the primaryshoulder.

If the box depth is too long by more than 1/32 inch,the box must be recut.

If the primary shoulder does not contact the gaugewhen used as shown in the figure, the depth should beinspected with measuring instruments that determinethe actual distance between the shoulders.

A Go/No Go gauge can be provided by Grant Prideco tofield check double shoulder connections primary shoul-der to secondary shoulder pin length and box depth. Thegauge does not provide dimensional information on thepin length or box depth.

29

Special Considerations WhenInspecting XT and XT-MConnections The stab flank to crest radius of the starting four to

five threads of the pin and box connections round offduring break-in and normal operation. Minor threaddamage may occur within these starting threads.This is not detrimental to the connection and shouldbe removed with a soft grinding wheel or a file.

The XT-M connection contains a 15 M-T-M seal nearthe pin and box secondary shoulders. This is the pri-mary sealing surface for the connection.

o Round pit type defects up to 1/32 inch indiameter and not exceeding 1/32 inch indepth are permissible.

o Multiple pits of this type are acceptable provided there is at least 1 inch circumferential separation between them.

o Circumferential lines or marks are acceptable provided they cannot be detected by rubbing a fingernail across thesurface.

o Areas highlighted in the figure below are the non-contacting areas of the seal. Damageor pitting is permitted in these areas of theseal, provided the balance of the contact surface is without damage exceeding the requirements above.

o XT-M connections may not be refaced.Damages exceeding requirements for the threads, seal and/or shoulder faces requirethe connection to be faced/chased.

HEAVY

HTD

RILL

PIPE

Heavy weight drill pipe (HWDP) was developed to provide agradual transition from heavy drill collars to relatively light-weight drill pipe. By providing a gradual change in weight andrigidity, HWDP reduces connection fatigue problems andincreases drill stem service life. And because it bends moreeasily than drill collars, it simplifies directional control in high-angle and horizontal drilling. HWDP has less wall contactthan drill collars, reducing differential sticking tendencies.Spiraled HWDP configurations further decrease differentialsticking tendency while helping to remove cuttings out of theannulus. Grant Prideco offers three types of HWDP configu-rations to meet the challenge of severe drilling conditions.

Conventional HWDP Developed to provide a grad-ual transition from the heavy drill collar to the relativelylightweight drill pipe.

Care And MaintenanceInitial Make UpEven though quality connections are heavily coatedwith phosphate, thread damage is not always pre-vented. A generous and thorough application of high-quality thread dope (40 to 60 percent metallic zincminimum) will help prevent galling.New connections should be walked in with chaintongs. Always use the recommended make-up torquefor the thread design. Exercise care to maintain calibrated torque measuring and indicating gauges forfuture use. After initial make-up, break-out the con-nection, visually inspect, redope and make-up twomore times before running in the hole.

Note: Monitor break-out torque, it should be lessthan or no greater than make-up torque. If itis greater, the connection should be cleaned,inspected and repaired, before it is made upagain.

MaintenanceUse thread protectors on both connections when handling drill collars. Alternate different joints on eachtrip. Clean and inspect the individual connections.

Qualified personnel should periodically conduct amagnetic particle/black light inspection. Collars thatare left idle or put in storage, should be cleaned,inspected, repaired and rust-proofed, as necessarybefore installing thread protectors.

Field WeldingExtreme caution should be used when welding drillcollar material in the field. This material is high alloysteel, carefully heat-treated to provide optimum per-formance. When repair welding or hardbanding, useproper preheat, interpass and post-heat temperaturesto prevent cracking and metallurgical degradation ofthe collar.

Your Grant Prideco authorized repair facility can pro-vide welding repair service to factory specifications toensure weld area integrity. Contact your representa-tive today for more information.

Drill Collars

Care And Maintenance

Bending Strength RatiosSizes below six inches should have a BSR of 2.25:1to 2.75:1. Conditions which require high rpm andsmall collars compared to the hole size, use 2.25:1 to2.85:1. For abrasive conditions, use 2.50:1 to 3.00:1.If the rpm is kept low and the collars are closer to thehole size, use 2.25:1 to 3.20:1. In corrosive environ-ments, use 2.50:1 to 3.00:1.
