Proper break-in is probably the most important factor affecting the life of the tool joint connection. Here are some recommendations to follow: 1. Proper make-up torque is determined by the connection type, size, OD and ID and may be found in torque tables. 2. Make up connections slowly, preferably using chain tongs. (High speed kelly spinners or the spinning chain used on initial make-up can cause galling of the threads). 3. Tong them up to the predetermined torque using a recently calibrated torque gauge to measure the required line-pull. Note: Monitor breakout torque. It should be less than or no greater than make-up torque. If it is greater, the connection should be cleaned, inspected and repaired, before it is made up again. 4. Breakout, visually inspect, redope and make up two more times before running in hole. Always use backup tongs to make and break connections. 5. Stagger breaks on each trip so that each connection can be checked, redoped and made up every second or third trip, depending on the length of drill pipe and size of rig. A new string of drill pipe deserves good surface handling equipment and tools. Check slips and master bushings before damage occurs to the tube. (See the IADC Drilling Manual for correct measurements). Do not stop the downward movement of the drill stem with the slips. This can cause crushing or necking down of the drill pipe tube. The drill pipe can also be damaged by allowing the slips to ride the pipe on trips out of the hole. Good rig practices will help eliminate time consuming trips in the future, looking for washouts or fishing for drill pipe lost in the hole. For more information refer to the 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 Latest Edition. The make-up values are lower due to the combined torsional and tensile loads found in service conditions.

Types of Grant Prideco Double Shoulder Connections There are three types of double shoulder connections offered by Grant Prideco. • HI TORQUE® (HT) – First generation double shoulder connection providing approximately 40% more torque capacity than API connections of equivalent dimensions. Not interchangeable with API connections. • eXtreme® Torque (XT® ) – Second generation double shoulder connection providing approximately 70% more torque capacity than API connections of equivalent dimensions. Not interchangeable with API connections. Two primary differences exist between HT and XT connections: 1) XT has a flatter taper and 2) XT has increased thread root radii. o eXtreme® Torque with Metal-To-Metal Seal (XTM™) – Industry first gas tight pressure rated rotary shoulder connection achieved through a 15° metalto-metal (M-T-M) seal on the pin nose. Provides torque capacity similar to that of XT connections. Not interchangeable with API connections.

• Grant Prideco Double Shoulder™ (GPDS™) – Double shoulder connection which is interchangeable with API connections and provides 20-50% more torque capacity than API connections of equivalent dimensions. The below figure illustrates the taper difference between HT and XT connections.

The following sections provide general guidelines for running and handling double shoulder connections. Connection-specific running and handling procedures are available direct from Grant Prideco and can be downloaded from www.grantprideco.com.

Tool Joint Break-in Most drill pipe connections are broken-in during manufacture. The following break-in procedure is recommended for connections which have not been broken-in during manufacture. Step 1:

Make the joints up to the maximum recommended make-up torque, and then break them out. If the break-out torque is less than the make-up torque, the joints do not have to be separated.

Step 2:

Make the joints up again to the same make-up torque and break them out. Separate the pin and box and reapply thread compound.

Step 3:

Make the joints up again to the same makeup torque and they are ready for service.

Note:

The break-out torque should be less than the make-up torque. If the break-out torque is more than the make-up torque, separate the joints and inspect them for damage.

Picking Up Pipe with Double Shoulder Connections for the First Time • Visually examine the thread protectors for damage such as dents or crushing. If any thread protectors are damaged, inspect the threads on that joint for damage. • If the joints were shipped to the rig with rust preventive on the threads, it must be removed. Use soap and water, steam or a vapor degreasing solvent such as Varsol. No residue should remain on the threads after cleaning. • If the joints were shipped to the rig with thread compound, it is not necessary to remove the thread compound 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 primary make-up shoulders and secondary make-up shoulders must be coated with a good quality rotary shouldered connection thread compound.

17

Special Considerations When Running XT® and XT-M™ Connections • Check to ensure the counterbalance on the top drive is working properly and provides a minimum amount of weight applied to the connection during make-up. • Ensure the bore through the top drive bell stabbing guide (top drive flipper) is no more than 1/2" larger in diameter than the box tool joint diameter. • Because of the flatter taper, XT and XT-M pins do not stab as deeply into the box as do HT, GPDS™ and API connections. Alignment of the pin to the box when stabbing and spinning up is more critical for XT and XT-M connections. A stabbing guide is required when running XT and XT-M connections, and alignment should be verified before spinning up. • Proper alignment, along with slow initial make-up of the starting threads, is necessary with XT and XT-M connections. Use chain tongs or slow speed spinners when spinning in the starting threads. Highspeed spinners may be used after the starting threads are engaged. • Minor thread damage may occur within the starting threads. This is not detrimental to the connection and should be removed with a soft grinding wheel or a file.

18

Application of Thread Compound to Double 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 rotary shoulder connection thread compound. Copperbased thread compounds are recommended. • Some drilling fluids or drilling fluid additives may affect the frictional properties of the tool joint and thread compound. If this is the case, rinse the drilling fluid off the connections before applying thread compound. • Remove drilling fluid from the secondary shoulder and 15° M-T-M seal (XT-M) of the box before making up the connection for the trip in the hole. Trapped drilling fluid can promote corrosion of the secondary shoulders. • Racking the pipe will wipe thread compound off the pin nose. If pins are doped coming out of the hole, reapply compound to the secondary shoulder before the connections are made up. • NOTE: For XT-M connections, localized corrosion or pitting may occur on the 15° M-T-M seal if racked back without thread compound applied to it. This is more common with completion fluids than common drilling fluids. Apply a liberal and even coat of quality thread compound to the 15° seal when racking back XT-M connections.

Tonging, Proper Gripping of the Box During 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 not required for XT boxes less than 46 and all GPDS™ boxes. • The threads of a long double shoulder box are about 1-1/2 inches further away from the makeup shoulder than the threads of an API box. Tongs or top drive torque wrenches should engage these long double shoulder boxes at the same location in relation to the threads that they would engage an API joint. • On the Varco BJ® PH85 pipe handler torque wrench, this can be accomplished by decreasing the length of the saver sub from 7 inches to 5-1/2 inches. This will put the tong dies 2 inches from the box make-up shoulder. • Back-up tongs should always be used

2 inches

Recommended Tonging Area

Tong Height • Bucking up tool joints with tongs can put high bending loads in the pipe. • Review the IADC Drilling Manual Latest Edition, or Tong Height Figure in API RP 7G Latest Edition about height of tool joint above slips to prevent bending pipe during tonging.

Alignment when Making up Connections • Galling and other damage can occur during stabbing 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 against the flank of the mating thread. This can cause high contact 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 cause high loads on threads. • NOTE: Alignment of the pin to the box when stabbing and spinning up is more critical for XT® and XT-M™ connections. A stabbing guide is required when running XT and XT-M connections and alignment should be verified before spinning up.

Pin

Contact of sharp edge of pin 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 makeup torque. High break-out torque is an indication of downhole make-up or thread damage. • Do not let the end of the pin strike the box make-up shoulder when stabbing the pin in the box. Stabbing guides are required for XT and XT-M connections and recommended for HT and GPDS™ connections.

22

Standing Pipe Back • Using normal drill pipe care and handling practices, no special care is required to protect the pin nose when standing the pipe back. The pin nose is not a seal. Minor damage to the pin nose from standing the pipe back does not affect the connection’s performance. • It is not necessary to use thread protectors when standing the pipe back. • Do not use pressed steel thread protectors when standing the pipe back. They could allow the weight of the stand to be supported by the primary make-up shoulder of the connection on the sharp edge of the thread protectors. • Apply a liberal and even coat of quality thread compound to the 15° M-T-M seal when racking back XT-M™ connections.

Sharp edge of thread protector can damage shoulder.

23

Downhole Make-up • Downhole make-up can be detected by high breakout torque. The break-out torque should be less than the make-up torque. • If downhole make-up is suspected, punch mark the pin and box next to the make-up shoulders when tripping into the hole (after the connection is made up). • If downhole make-up occurs, the position of the punch marks will change. • Downhole make-up can cause — Compressed box counterbores — Compressed pin noses

Milled Hardness Flat Punch marks

Apply punch marks in line with hardness flat to make them easier to find.

The following sections provide information and general guidelines regarding the field inspection of Grant Prideco double shoulder connections and are not intended to replace Grant Prideco Field Inspection Procedures and Drawings. Connection type-specific Field Inspection Procedures and connection type and size-specific Field Inspection Drawings are available direct from Grant Prideco and can be downloaded from www.grantprideco.com.

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 backup 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 current Grant Prideco Field Inspection Procedures for the applicable connection type. • Proper operation and correct shoulder loads depend on the pin length and box depth of double shoulder connections being within specifications. The pin length and box depth are shown on the Field Inspection Drawing for the particular size and type connection. • No more than 1/32 inch should be removed from either the primary or secondary make-up shoulder at any one refacing. No more than 1/16 inch cumulatively should be removed from either the primary or secondary make-up shoulder. The correct pin length and box depth must be maintained when resurfacing make-up shoulders. • The Grant Prideco benchmark is a reference for checking how much material has been removed from make-up shoulders. • The surface finish of the primary make-up shoulder should be 150 RMS or less. • When Grant Prideco double shoulder connections are refaced, the bevel does not need to be remachined.

25

• The pin nose is not a seal, it is a mechanical stop. The pin nose must be free of raised metal or other imperfections that could prevent proper make up or cause galling. Pin nose damage can be repaired with a hand file.

Checking Pin Length • The pin length can be checked with a dial indicator or depth micrometers. If the pin length is short by 1/32 inch or less, the pin can be repaired by resurfacing the primary shoulder. • If the pin length is short by more than 1/32 inch, the pin must be recut. • If the pin length is too long by 1/32 inch or less, the pin 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 to field check double shoulder connections’ primary shoulder to secondary shoulder pin length and box depth. The gauge does not provide dimensional information on the pin length or box depth.

If the pin nose does not contact the gauge when used as shown in the figure, the length should be inspected with measuring instruments that determine the actual distance between the shoulders.

27

Checking Box Depth • The box depth can be checked with a dial indicator or depth micrometers. If the box depth is short by 1/32 inch or less, the box can be repaired by resurfacing the secondary shoulder. • If the box depth is short by more than 1/32 inch, the box must be recut. • If the box depth is too long by 1/32 inch or less, the box can be repaired by resurfacing the primary shoulder. • If the box depth is too long by more than 1/32 inch, the box must be recut.

A Go/No Go gauge can be provided by Grant Prideco to field check double shoulder connections’ primary shoulder to secondary shoulder pin length and box depth. The gauge does not provide dimensional information on the pin length or box depth.

If the primary shoulder does not contact the gauge when used as shown in the figure, the depth should be inspected with measuring instruments that determine the actual distance between the shoulders.

28

Special Considerations When Inspecting XT® and XT-M™ Connections • The stab flank to crest radius of the starting four to five threads of the pin and box connections round off during break-in and normal operation. Minor thread damage may occur within these starting threads. This is not detrimental to the connection and should be removed with a soft grinding wheel or a file. • The XT-M connection contains a 15° M-T-M seal near the pin and box secondary shoulders. This is the primary sealing surface for the connection. o Round pit type defects up to 1/32 inch in diameter and not exceeding 1/32 inch in depth 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 the surface. o Areas highlighted in the figure below are the non-contacting areas of the seal. Damage or pitting is permitted in these areas of the seal, 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 require the connection to be faced/chased.

HEAVY WEIGHT DRILL PIPE

Heavy weight drill pipe (HWDP) was developed to provide a gradual transition from heavy drill collars to relatively lightweight drill pipe. By providing a gradual change in weight and rigidity, HWDP reduces connection fatigue problems and increases drill stem service life. And because it bends more easily than drill collars, it simplifies directional control in highangle and horizontal drilling. HWDP has less wall contact than drill collars, reducing differential sticking tendencies. Spiraled HWDP configurations further decrease differential sticking tendency while helping to remove cuttings out of the annulus. Grant Prideco offers three types of HWDP configurations to meet the challenge of severe drilling conditions.

Heavy Weight Drill Pipe · Tri-Spiral™ HWDP – Developed for high-angle applications such as extended reach and horizontal drilling. - Equally spaced, three spiral upset design helps improve cuttings removal, reduce differential sticking tendencies and torque and drag.

Drill Collars Care And Maintenance Initial Make Up Even though quality connections are heavily coated with phosphate, thread damage is not always prevented. A generous and thorough application of highquality thread dope (40 to 60 percent metallic zinc minimum) will help prevent galling. New connections should be “walked in” with chain tongs. Always use the recommended make-up torque for the thread design. Exercise care to maintain calibrated torque measuring and indicating gauges for future use. After initial make-up, break-out the connection, visually inspect, redope and make-up two more times before running in the hole. Note: Monitor break-out torque, it should be less than or no greater than make-up torque. If it is greater, the connection should be cleaned, inspected and repaired, before it is made up again. Use thread protectors on both connections when handling drill collars. Alternate different joints on each trip. Clean and inspect the individual connections. Qualified personnel should periodically conduct a magnetic particle/black light inspection. Collars that are left idle or put in storage, should be cleaned, inspected, repaired and rust-proofed, as necessary before installing thread protectors.

Field Welding Extreme caution should be used when welding drill collar material in the field. This material is high alloy steel, carefully heat-treated to provide optimum performance. When repair welding or hardbanding, use proper preheat, interpass and post-heat temperatures to prevent cracking and metallurgical degradation of the collar. Your Grant Prideco authorized repair facility can provide welding repair service to factory specifications to ensure weld area integrity. Contact your representative today for more information.

DRILL COLLARS

Maintenance

Care And Maintenance Bending Strength Ratios Sizes below six inches should have a BSR of 2.25:1 to 2.75:1. Conditions which require high rpm and small collars compared to the hole size, use 2.25:1 to 2.85:1. For abrasive conditions, use 2.50:1 to 3.00:1. If the rpm is kept low and the collars are closer to the hole size, use 2.25:1 to 3.20:1. In corrosive environments, use 2.50:1 to 3.00:1.

*NOTE 1:

Torque figures preceded by an asterisk indicate that the weaker member for the corresponding outside diameter (OD) and bore is the BOX. For all other torque values the weaker member is the PIN.

NOTE 2:

In each connection size and type group, torque values apply to all connection types in the group, when used with the same drill collar outside diameter and bore, i.e. 2 3/8, API IF, API NC 26, and 2 7/8 Slim Hole connections used with 3 1/2 x 1 1/4 drill collars all have the same minimum make-up torque of 4,600 ft.-lb., and the BOX is the weaker member.

1 Basis of calculations for recommended make-up torque assumed the use of a thread compound containing a 0.08 coefficient of friction, applied thoroughly to all threads and shoulders, and using the modified Jack Screw formula in Appendix A, paragraph A.8 and a unit stress of 62,500 psi in the box or pin, whichever is weaker. 2 Normal torque range is tabulated value plus 10%. Higher torque values may be used under extreme conditions. 3 Make-up torque for 27/8 PAC connection is based on 87,500 psi stress and other factors listed in footnote1. 4 Make-up torque for H-90 connection is based on 56,200 psi stress and other factors listed in footnote1.

* The minimum size drill collar, calculated from the Lubinski and Hock equation, with the specific sizes of hole and casing combination, is too large for conventional fishing tools. When the minimum drill collar diameter is too large to washover and/or catch with an overshot, other steps should be taken. Some of the possibilities are as follows: • Use turned down casing couplings. • Use integral joints on casing. • Under-ream the hole. • Run smaller size casing. * Use a packed hole assembly instead of a pendulum. ** Not API standard size drill collar.

Picking Up a New Kelly

Under ideal conditions, a new Drive Bushing assembly should be used when picking up a new kelly. If this is not possible, the following checklist should be performed: 1. Inspect surfaces on Drive Bushing rollers for wear. Example: For a 51/4 inch Hex, if wear exceeds 1/8 inch, reverse the rollers. 2. Check clearance between roller face and side of kelly. Example: For a 51/4 inch Hex, if clearance is more than 1/8 inch, inspect roller assembly and Kelly Bushing for excessive wear. 3. Inspect bottom taper of Drive Pins for wear and damage. Replace as necessary. 4. Inspect for clearance between upper and lower halves, replace if clearance is zero. Remember, a worn out Drive Bushing can severely damage a new kelly.

Formulas Used In Well Control and Drilling Operations A. Calculating Pressure, psi and Pressure Gradients, psi/ft. 1. Determine pressure gradient, psi/ft. (Mud Weight, ppg.) x (0.052) = psi/ft. 2. Determine hydrostatic pressure, psi (H.P.) (Mud Wt., ppg.) x (0.052) x (T.V.D., ft.) = psi 3. Maximum allowable shut in casing pressure

(

Maximum Allowable Mud Wt., ppg

) -(

Mud Wt. in use ppg

)

x(0.052)x(TVD, ft.)= psi

Test to determine H2S 50 ml HCl (mild hydrochloric solution) 50 ml H2O 1 gram NaASO2 (sodium arsenite) 3 drop liquid dish water soap yellow positive sign won’t determine degree

108

B. Converting Pressures, psi into mud weight, ppg. (NOTE: Anytime a pressure is to be converted to mud weight, the following formula is used.) All of the following use the same formula: Pressure, psi

= Mud Weight, ppg

0.052 x TVD, ft. Using the calculator, this formula is worked as follows: (Pressure, psi) ÷ (0.052) ÷ (TVD, ft) = Mud Weight, ppg. 1. Kill Weight Mud, ppg. (SIDPP, psi)- (0.052) - (TVD, ft) + (O.M.W.) = Kill Wt., ppg. 2. Equivalent Mud Weight = ppg. (E.M.W.) (pressure, psi) ÷ (0.052) ÷ (TVD, ft) = E.M.W., ppg 3. Equivalent Circulating Density, ppg (E.C.D.)

(

Annular Pressure Loss, psi

)

÷ (0.052) ÷ (TVD, ft.) + (O.M.W.) = E.C.D., ppg

4. Maximum Allowable Mud Weight, ppg.

(

Leak-Off Pressure psi

)

÷ (0.052) x (TVD, ft.)+

Test Mud = ppg. Weight

( )

5. Converting Pressure Gradient, psi/ft to Mud Wt., ppg (Pressure Gradient, PSI/ft.) ÷ (0.052) = Mud Wt., ppg. O.M.W. (original mud weight) SIDPP (shut in drill pipe pressure) TVD
