EXPANDED PRODUCT LINEOver the years, Prudential has adapted to the changing needs of its customers

by expanding its product line and offering new products to the marketplace.

One of Prudential’s latest developments is PS80 grade casing. PS80 is an “as

rolled” proprietary casing specification with a minimum yield strength of 80,000

PSI. External stress tests have indicated a lower level of strength loss than usually

experienced with L80 seamless product.To complement PS80 we have a

working relationship with Hunting Interlock of Houston,Texas, to supply the

BOSS connection on thermal applications.

PREMIUM PIPE THREADING FACILITYPrudential added a premium pipe threading facility to apply premium threads not

only to our HFIW Tubular Products, but also to other pipe products that hold

higher values than HFIW.

In keeping with our commitment to provide our customers with products

that will meet their demanding and ever-changing needs as well as focusing

on convenience and service, Prudential is associated with Hydril and Hunting

Interlock.We offer customers the following Premium Connections, making

Prudential a “one-stop-shop” for those who require such threads.

• Hydril Series 500 Wedge Thread• Hydril 563 Thermal Connection• Hunting Interlock Boss, SLHT• Hunting 40-40 Tubing & Casing Connections

Prudential has worked hard to add value to its products for its customers and to provide excellent service tothe superior products we sell.

Governing Standard API API Prudential Steel Ltd. Prudential Steel Ltd.

1. OUTSIDE DIAMETER (Nominal size, D)

The tolerance on outside diameter of tubing and casing is based on the nominal size of the tube:

Outside Diameter, D mm in. Tolerance on Diameter mm in.101.6 and less 4 and less +/- 0.79 +/- 0.030

114.3 and larger 4.5 and larger + 1 per cent - 0.5 per cent

2.WALL THICKNESS (Nominal wall, t)

The tolerance on wall thickness is +/-12.5% of the nominal wall for all sizes and weights, both tubing and casing.

3. DRIFT TEST (Drift diameter)

Each length of tubing and casing must allow passage of a cylindrical drift mandrel, without undue restriction or applied force.The drift mandrel is to be cylindrical inshape – not “bone” shaped. In order to properly drift pipe, the inside surfaces of the joint must be free of all foreign matter and the pipe adequately supported so as toprevent sagging under its own weight.The diameter of the drift mandrel is based on the inside diameter, d, of the pipe. Dimensions of the drift mandrel are as below:

Product & Size mm in. Drift Mandrel Length mm in. Drift Mandrel Diameter mm in.Casing 219.0 and less 8-5/8 and less 152.4 6.00 d – 3.18 d – 0.125

NOTES• Joint strength is lesser of either the connection fracture or pull-out

strengths, as determined by calculations per API Bulletin 5C3.

• All tensile, burst, and collapse ratings are based on minimumperformance properties and do not include any safety factors.Safety factors should be included when determining workingpressures and permissible tensile loads.

• The setting depth calculated is based on the minimum valuedetermined by the collapse, burst, or joint strength limitations of theparticular combination of size/weight/grade/connection.A collapseand burst gradient of 11.3kPa/m (0.50psi/ft.), or an equivalent mudweight of 1,000kg/m3 (9.625ppg) – fresh water – is assumed. Inthese calculations, a Safety Factor of 1.0 is used for burst andcollapse, and a Safety Factor of 1.6 is used based on joint strength.

• If heavier mud weights or higher pressures are anticipated, thesetting depth must be recalculated based on the expected loads.

• Bending loads from deviated wellbores and thermal stresses willaffect both pipe body and connection ratings. In certain cases, theeffects from bending or thermal effects can be substantial. Pleasecontact Prudential Steel for specific case information.

• The use of Special Clearance connections can result in connectionperformance being downgraded. Please contact Prudential Steel forspecific case information.

• The use of any casing grade in a sour environment may require theapplication of additional safety factors.

• Casing wear from subsequent drilling operations may require theapplication of additional safety factors.

A string of casing for a particular application is designed around the expectedoperating conditions.The operating conditions (internal and external pressure,tension) generate loads on the casing, and the casing string must be able towithstand these loads without failure.To perform a casing string design, theoperational loads are compared to the minimum performance properties, andthe parameters of the casing selected such that the minimum performanceproperties are greater than the expected loads.

The designer must consider: the internal operating pressure against the casing’sburst rating or the connection leak resistance; the external operating pressureagainst the casing’s collapse resistance; and, the tensile loads, usually from thecasing’s own weight, against the joint strength.As pressures are commonlydescribed as radients (kPa/m or psi/ft.) and the weight of the casing string isdescribed as some mass per unit length (kg/m or lb./ft.), the operational loads at a given depth can be readily determined.Alternately, actual values of theexpected loads may be known and compared against the the tabulatedminimum performance properties.

The operational limits of the casing will be governed by one of the following:• Joint strength – either fracture or pull-out • Collapse resistance• Burst resistance or connection leak resistance

Consequently, once the limiting operational condition is determined, themaximum operating depth of the casing string can be calculated based on thatcondition.

The Setting Depths in the “Casing Dimensional and Minimum PerformanceData” are calculated in this manner. In some instances, the operational limit of aspecific size/weight/grade and connection combination is the collapse resistance,in others the burst, and in yet others, the joint strength.A depth correspondsto this limit, and that value is the Setting Depth.

In all Setting Depth calculations for casing, a Safety Factor is accounted for inthe tabulated values.The Safety Factors used are those commonly accepted bythe Energy and Utilities Board in Alberta: 1.0 for Burst and Collapse; and, 1.6 forTension.These Safety Factors provide for somewhat conservative Setting Depthvalues, since the calculations are based on the minimum – not nominal –performance properties of the casing. However, in certain situations, thedesigner may elect to use Safety Factors greater than those above. If there is arisk of casing wear for example, the designer may choose one weight heavierpipe to allow for the wear with no loss in burst or collapse, but the extraweight must be dealt with in the tensile calculations with the possible risk ofthe preferred weight/grade/connection combination being unsuitable. Further, insituations where high pressure stimulation treatments are expected, greaterburst capability may be desired, and a higher grade or heavier weight of casingselected for the bottom section of the hole.Additionally, if the risk ofencountering H2S is great, the design may be modified so as to reduce thestress levels in the casing string by selecting higher grades or heavier weights.Finally, if the casing is to be run in a deviated wellbore or subjected to thermalrecovery, the design must accommodate the loading extremes anticipated, andthe Safety Factors adjusted accordingly.

NOTE: The information in this section is taken from API RP 5C1,“Recommended Practice for Care and Use of Casing and Tubing”,Seventeenth Edition, November, 1994. It is intended to provide anoverview of the field handling and assembly of casing products. Otherinformation may be required, and the user is advised to obtain andreview a copy of RP 5C1.

This information is directed primarily at API connections, though some isapplicable to Specialty connection products. In any event, if the casing isequipped with Specialty connections, refer to the manufacturer'sRecommended Practice for handling and running.

I UNLOADING • Ensure that pipe racks are level and properly positioned to allow transfer of

casing from the rack to the catwalk.

• Ensure that thread protectors are in place on all connections beforeunloading casing.

• Avoid rough handling of casing which might dent or damage in any fashionthe pipe body or connections. Dents in the casing body can reduce collapseratings and lead to failure in service.

• Do not unload casing by dropping joints onto the racks. Maintain control ofthe casing at all times by handling a small number of joints.

• Do not place hooks in the ends of casing. Joints should be slung fromspreaders, evenly spaced along the joint.

• When rolling casing on the racks, do not allow joints to strike each other.

• Always leave thread protectors in place when the casing is being moved.

• Casing should be placed on level tumble racks or clean metal or woodensurfaces, free of any debris.

II PREPARATION AND INSPECTION • All casing and accessory equipment should be visually inspected before it is

run in the hole.Where possible, the function of accessory pieces should beconfirmed before assembly.

• Any joints with obvious pipe body or connection damage should be laidaside and not run. Further, any accessory pieces which are questionableshould not be used.

• The basic running order of the casing and accessories should be determinedearly, and the make/model/type of accessories verified.

• The size and condition of all related handling equipment should be checkedthoroughly – particularly, slips, elevators, back-up tongs, and power tongs.

III RIG FLOOR EQUIPMENT • The use of slip-type elevators for any length of casing string is strongly advised

and the condition of the dies and the setting plate should be checked.

• Extra-long slips should be used for heavy casing strings or for critical servicecasing. Again, the dies must be clean and sharp, and all of the same size. Donot mix old or resharpened dies with new dies in either the slips or theelevators.

• The condition of the slip bushing must also be checked to ensure that theslips will fit properly and engage the casing evenly.

NOTE: Slip and tong marks or gouges are injurious, and can result infailure of the casing in service. Properly fitting and well maintainedequipment can greatly reduce the chance of damaging the casing.

• Check that the blocks are centered over the rotary table. If not, make thecrew aware that the misalignment can result in difficulty when stabbing andspinning up connections.

• Check the rig-in of the power tongs, making sure that the tong back-up lineis at right angles to the tongs, the tongs are level, are free to move and areat the correct height above the floor.

• Check the size and rating of the power tongs.The nominal size of the tongsshould not be more than one size larger than the pipe being run (i.e. do notuse 13-3/8" tongs to run 7" casing) and the tongs must be able to readilyattain the maximum expected torque.

• Ensure that the power tongs are equipped with an accurate and reliabletorque gauge – either electronic or hydraulic, possibly equipped with apressure activated dump valve.

• Check that the back-up tongs are level and do not interfere with thesuspension or operation of the power tongs.

IV RUNNING PREPARATION • Remove pin and box protectors from casing and accessory pieces, and

thoroughly clean the connections, removing all previously applied thread orstorage compound.

• Inspect all connections, particularly noting any mechanical damage to thethreads.While minor corrosion damage is of little concern, mechanicaldamage of the threads can lead to failures in service. If a connection isdamaged or questionable, it should be laid aside.

• When inspecting the box connections, check to see that the couplings aremade-up power tight. On round thread connections there should be no pinthreads extending beyond the coupling face, and on Buttress connections,the coupling face should be even with the base of the triangle stamped onthe pin member.

• All casing joints and accessory pieces should be drifted full-length with astandard API drift mandrel, from the box end to the pin end. Depending oncircumstances, while it is preferable to drift casing on the racks, a rabbit maybe used instead as the casing is pulled up through the V-door.

• With the thread protectors removed and the connections cleaned, tally thecasing and accessory pieces by measuring the length from the face of thecoupling to the point on the pin connection where the coupling stops whenthe connection is assembled power tight.The distance from the end of thepin nose to this point is referred to as the “make-up loss”.Alternately, thetotal length of the joint can be measured, and the make-up loss subtractedfrom the overall length.Tallies should be made to the nearest 0.01m.

• The cleaning, inspection, and tallying operations are repeated as each tier ofcasing is uncovered.

• Before the casing is moved to the catwalk, clean thread compound shouldbe applied, and thread protectors must be replaced. Unless specifiedotherwise,API 5A2 type thread compounds should be used. Freshcompound should be used, the applicator brush must be clean and free ofany debris, compound must be mixed well, and never thinned.

• Note that certain service applications (heavy oil thermal or extremely highpressure) may require use of a different compound. In no event are rotaryshoulder (drill pipe or collar) compounds to be used.

HANDLING AND RUNNING GUIDELINES CASING


114.3 x 5.21 R3 GRADE PS8073 x 5.51 R2

• When moving pipe from the racks to the catwalk, ensure that joints are notdropped or allowed to hit against other casing or rig equipment. Casingshould be pulled up to the V-door with a choker, and then single jointelevators used to pull the casing joint into the derrick.Thread protectorsmust be in place on both pin and box connections any time the pipe oraccessories are moved.

• If it is impractical to replace all thread protectors, several can be cleanedand used repeatedly, being installed on the pipe rack and removed from thecasing when hung in the derrick.

• If a mixed string is to be run (more than one grade and/or weight), ensurethat sufficient pipe of the required type is available, and that it is laid out onthe racks so that it will be accessible when called for in the program.

V RUNNING CASING • Once the casing has been pulled into the derrick, the pin end thread

protector can be removed, thread compound applied (if required) and thejoint stabbed.

• In stabbing the joint, lower the casing slowly to avoid connection damage,and ensure that the connection is aligned before starting rotation. For largecasing, and if there is any misalignment of the blocks over the rotary, a manon the stabbing board can be of great assistance.

• If the casing does not stab correctly or jams, the pin should be picked upfrom the box, both connections cleaned, inspected, and repaired (removeany filings or wickers), thread compound re-applied, and the connection re-stabbed.

• Once the joint is stabbed, make-up can proceed, with the connection beingspun up slowly initially, ensuring that the connection is not cross-threadedor jammed.

• API Round and Buttress connections are assembled to position; theassembly torque values provided are representative of the torque rangerequired to attain the power-tight position based on nominal conditions, andmust be used only as a guide.Torque must relate to the make-up position,and as a result, the torques used in the field for a given connection can varyfrom those listed.

• A suggested procedure for casing make-up is as follows:

1. Assemble a number of connections (at least ten) from each particularmanufacturer or mill lot on location to establish the torque required toattain the power tight position.The torque required to attain thisposition may or may not be Optimum as listed in API RP5C1, and thetorque must be within the Minimum/Maximum range. For all weights andgrades, the power tight position, in turns past hand tight, is: 4-1/2" to 7"(114.3 to 177.8mm) – three turns; 7-5/8" (193.7mm) and larger – threeand one half turns, except 9-5/8" (244.5mm) and 10-3/4" (273.1mm) ingrade P110, and 20" (508mm) in grade J and K55, which are four turns.

2. During the initial spin up of the connections, watch for any irregularities inthe assembly (torque spikes, heat, etc.) as these may indicate dirtyconnections, damaged threads, cross threading, etc., which can compromisethe connection's integrity. If the initial spin up is erratic, the assembly shouldbe stopped, and the connection broken out, cleaned, and inspected. If nodamage is obvious, the assembly can be repeated, but if the initial spin up isagain erratic, the connection is suspect an should not be run.To reduce therisk of galling assembly speeds should be kept below 25 RPM.

3. As the assembly progresses, watch the position of the pin member lastscratch relative to the coupling face, and monitor the torque.

4. The Optimum torque value suggested should provide for a completemake-up under nominal conditions, with the pin thread last scratch flushwith the coupling face (the power tight position), plus or minus two turns.

5. If the pin thread last scratch is buried beyond the coupling face andMinimum torque has not been attained, the connection is suspect andshould not be run. Conversely, if at Maximum torque the pin thread lastscratch is not within three turns of the coupling face, the connection issuspect and should not be run.

6. If at Optimum torque several threads are still showing, the torqueshould be increased, up to Maximum, to see if the power tight positioncan be attained.

7. Once the ten or more connections are thus assembled a representativeOptimum torque for that particular lot can be determined, and thebalance of the connections run using this Optimum value.

8. Suspect connections should be broken out and laid down, and not rerununless inspected and repaired.The mating box connection should becleaned and inspected for damage after break-out.

• Note that when assembling the field connection, it is possible that the millend of the connection will make up slightly.This does not suggest that themill end is too loose, but rather that the field end torque applied is morethan was used to assemble the mill end.

• Casing must be lowered carefully, first to avoid shock loads to the casingstring, but also to prevent pressure surges which may damage downholeformations.The slips must not be set until all downward motion of thecasing string has stopped. Great care should be exercised to ensure that thestring does not spud the bottom of the hole – the compressive loads cancause the string to buckle and/or connections to loosen with thesubsequent risk of failure in service.

• Note that often there is a predetermined running order for casing and relatedaccessories – due to design criteria or downhole conditions. It is vital that thisorder be followed, and in the event that a specific joint of casing cannot beidentified with respect to its weight or grade, the joint should not be run.

VI POSSIBLE RUNNING PROBLEMS • Some of the more common causes of problems encountered when running

casing are:

1. Inadequate inspection of casing or connections prior to running.

2. Improper transportation, storage, and handling practices.

3. Ignorance of Recommended Practices for handling and running of casing.

4. Improper manufacture of accessory or repair facility producedconnections.

5. Use of improperly manufactured couplings for replacement parts oradditions.

6. Excessive spin up speeds for initial assembly.

7. Excessive or inadequate assembly torques applied.

8. Use of improper thread compound.

9. Use of poorly maintained equipment (slips, elevators, power tongs, etc.).

NOTE:The information in this section is taken from API RP 5C1,“RecommendedPractice for Care and Use of Casing and Tubing”, Seventeenth Edition, November,1994. It is intended to provide an overview of the field handling and assembly oftubing products. Other information may be required, and the user is advised toobtain and review a copy of RP 5C1.

The information is directed primarily at API connections, though some isapplicable to Specialty connection products. In any event, if the tubing isequipped with Specialty connections, refer to the manufacturer'sRecommended Practice for handling and running.

I UNLOADING • Ensure that the pipe racks are level and properly positioned to allow

transfer of tubing from the rack to the catwalk.

• Ensure that thread protectors are in place on all connections beforeunloading tubing.

• Avoid rough handling of tubing which might dent, bend, or damage in anyfashion the pipe body or connections. Mechanical damage of the pipe isinjurious, and can result in failure of the tubing in service. Particular caremust be taken when handling tubing with an internal plastic coating.

• Do not unload tubing by dropping joints onto the racks or by allowing pipeto tumble from the transport. Maintain control of the tubing at all times byhandling a small number of joints.

• Do not place hooks in the ends of the tubing. Joints should be slung fromspreaders, evenly spaced along the joint.

• When rolling tubing on the racks, do not allow joints to strike each other.

• Always leave thread protectors in place when the tubing is being moved.

• Tubing should be placed on level tumble racks or clean metal or woodensurfaces, free of any debris.

II PREPARATION AND INSPECTION • All tubing and accessory equipment should be visually inspected before it is

run in the hole.Where possible, the function of accessory pieces should beconfirmed before assembly.

• Any joints or accessories with obvious body or connection damage shouldbe laid aside and not run. Any accessories which are questionable shouldnot be used.

• The basic running order of the tubing and accessories should be determinedearly, and the make/model/type of accessories verified.

• The size and condition of all related handling equipment should be checkedthoroughly. Particularly, slips or tubing spiders, back-up tongs, elevators, andpower tongs.

III RIG FLOOR EQUIPMENT • While the use of slip-type elevators is preferred for any length of tubing

string, their use is strongly recommended for long or heavy strings, and forSpecial Clearance and Specialty Connection equipped tubing.

• Check the elevator body, latch mechanism, links, and dies and setting plate ifslip-type elevators are used.The elevators must close completely, and thelatch engage properly for safety.

• If slips are used, ensure the dies are clean and sharp, and all of the same size.Do not mix old or resharpened dies with new dies in either the slips of theelevators.

• If a tubing spider is used, ensure it does not crimp the tubing when closed, andalso that it releases completely to avoid gouging the tubing when lowering.

• Slips and elevators should be cleaned frequently during use to reduce therisk of slippage, and to ensure their correct function.

• The condition of the slip bushing must also be checked to ensure that theslips will fit properly and engage the tubing evenly.

NOTE: Slip and tong marks are injurious, and can result in failure of the tubing inservice. Properly fitting and well maintained equipment can greatly reduce the risk of damaging the tubing.

• Check that the blocks are centered over the rotary table. If not, make thecrew aware that the misalignment can result in difficulty when stabbing andspinning up connections.

• Check the rig-in of the power tongs, making sure that the tong back-up lineis at right angles to the tongs, the tongs are level, are free to move and areat the correct height above the floor.

• Check the size and rating of the power tongs.The nominal size of the tongsshould not be more than one size larger than the tubing being run (i.e. donot use 7" tongs to run 3-1/2" tubing) and the tongs must be able to readilyattain the expected maximum torque.

• Ensure that the power tongs are equipped with an accurate and reliabletorque gauge – either electronic or hydraulic, possibly equipped with apressure activated dump valve.

• Check the size and condition of the back-up tongs.They must be sizedproperly, have clean and sharp die segments, and be in good repair to avoid damaging the tubing.The use of pipe wrenches as back-ups is notpermissible under any circumstance. Check that the back-up tongs are leveland do not interfere with the suspension or operation of the power tongs.

IV TUBING PREPARATION • Remove pin and box protectors from tubing and accessory pieces, and

thoroughly clean the connections, removing all previously applied thread orstorage compound.

• Inspect all connections, particularly noting any mechanical damage to thethreads.While minor corrosion damage is of little concern, mechanicaldamage of the threads can lead to failures in service. If a connection isdamaged or questionable, it should be laid aside.

• When inspecting box connections, check to see that the couplings are madeup power tight. On pup joints and accessories, the couplings may be only spun on by hand, and may not have thread compound applied to theconnection surfaces. On round thread connections, there should be no pinthreads extending beyond the coupling face.

• All tubing joints and accessory pieces should be drifted full-length with astandard API drift mandrel, from the box end to the pin end.While it ispreferable to drift the tubing on the racks, a rabbit may be used instead asthe tubing is pulled up through the V-door.

• With the thread protectors removed and the connections cleaned, tally thetubing by measuring from the face of the coupling to the point on the pin connection where the coupling stops when the connection is assembledpower tight.The distance from the pin nose to this point is referred to asthe “make-up loss”. Alternately, the total length of the joint can bemeasured, and the make-up loss subtracted from the overall length.Talliesshould be made to the nearest 0.01m.

• The cleaning, inspection and tallying operations are repeated as each tier oftubing is uncovered.
