Grant Prideco provides the industry with the three most important considerations for drill pipe: quality, technology and economy. Manufacturing processes are vertically integrated from raw material to finished product. Pipe is supplied

by the Company’s own mill and tool joints are forged in its own

facilities.

Drilling Products & Services also offers all the features of a fully

integrated service company. Beyond full technical and field support

for its products, Grant Prideco provides an array of other services,

including training and seminars, tool joint break-in prior to delivery

and a worldwide repair and accessory manufacturing network.

DRILL PIPE

Drill Pipe Design and ManufacturingDesignDrill pipe life is extended by creating a design that is inherently

fatigue resistant. When drill pipe rotates in a bent condition,

alternating tensile and compressive stresses can cause fatigue

cracks that may ultimately result in drill pipe “washouts” and

failure. Stresses tend to concentrate in areas where geometries

change rapidly. The shorter or more irregular the transition, the

higher the stress concentration. Alternately, the longer and

smoother the transition, the lower the stress.

The thick weldneck, required for adequate weld strength and the short internal upset of a standard industry design concentrates stress in the adjacent pipe body.

The weldneck/upset design incorporates a counterbored weldneck, an extended internal upset length, a shallow internal taper angle and generous radii to produce the optimum stress-reducing geometry.

DRILL PIPE

GeometryThe critical section of a joint of drill pipe is the transition from the

pipe body to the tool joint. This section consists of the weld that

joins the pipe and tool joint, and the transition from the thin

cross-section of the pipe to the thick cross-section of the tool joint.

The challenge to the drill pipe designer is to ensure that the weld is

stronger than the pipe body and the transition between the pipe

body and the tool joint is as seamless as possible.

Grant Prideco’s weldneck/upset design was engineered to

maximize fatigue resistance in this critical transition. A geometry

that minimizes stress concentrations is employed. The assembly is

configured to optimize the transition from the cross-section of the

pipe to the tool joint. The length of the internal upset is extended,

producing a shallow fade-away angle that blends into the pipe

body’s inside diameter with a liberal radius. To further improve

fatigue resistance, the surface finish of the assembly adjacent to

the weld line is improved by grinding on both the inside and

outside diameter.

The enhanced hardenability of Grant Prideco’s specially engineered tool joint steel produces more uniform microstructure and mechanical properties throughout the entire cross-section in comparison with standard 4137H steel.

The increased hardenability of Grant Prideco’s proprietary tool joint material provides more consistent mechanical properties through the tool joint sections, such as the critical section at the last engaged thread, especially on recut joints.

HARDENABILITY CURVE TOOL JOINT MATERIAL

Proprietary Steel Grant Prideco incorporates specially designed proprietary steel for

both the drill pipe tube and the tool joint. Tube and billets are

produced by Grant Prideco mills in Austria and China or obtained

from qualified suppliers, and thoroughly inspected upon receipt to

verify that all material requirements are met. By closely matching

the chemistries of the tube and tool joint materials, Grant Prideco

ensures good weld compatibility and weld strength. Stringent

cleanliness requirements for both materials enhance fracture

toughness. The increased hardenability of the materials consis-

tently produces more uniform mechanical properties throughout

the entire cross-section, commanding adequate strength in the

weld zone and the critical sections of the connection. The result is

a more reliable product. For both API drill pipe and high-perfor-

mance, severe-environment products, Grant Prideco engineers

materials that increase product performance and integrity.

DRILL PIPE

Tube ProcessingGrant Prideco drill pipe is manufactured with state-of-the-art

production equipment. Tube ends are forged on modern Ajax

upsetters featuring programmable heating systems, which

optimize forging efficiency. The computer-controlled pipe handling

system operates cleanly and quietly to transfer tubes quickly and

without damage. Grant Prideco’s modern austenitizing and

tempering furnaces provide a controlled quench-and-temper heat

treatment process for tubes. Tensile and impact properties are then

verified through rigorous testing.

Tool Joint ProcessingGrant Prideco’s computer-controlled, automated forge line

efficiently produces tool joints while reducing risk to employees.

Forged tool joints are precision contoured on modern machining

centers, then batch heat-treated by a controlled atmosphere

quench-and-temper process. API or Grant Prideco proprietary

rotary-shouldered connections are threaded onto the tool joint

using Computer Numerically Controlled (CNC) machine tools.

Tube ends are forged on a modern Ajax upsetter.

Computer controlled pipe handling system quickly transfers tube quietly and without damage.


DRILL PIPE

WeldingA friction or inertia weld process joins tubes and tool joints. Both

processes are highly reliable and cost-effective, and produce

consistent and uniform weld zone properties. In terms of weld

quality, reliability, strength or metallurgical effects, both processes

produce a high-integrity, solid-state weld connection between the

tool joint and the drill pipe tube. The principles of both welding

processes are based on the rotation of one surface against another

at a relatively high speed and under heavy pressure. The friction

between the tool joint surface and the tube surface causes the

contact to heat up below the melting temperature at which they

are forged together, producing the weld.

Grant Prideco’s latest MTI400VX weld line system is fully auto-

mated and features a computerized process and data system.

Robotic handling and laser control position systems provide

efficient operation and assure precise alignment between the tool

joint and tube. Subsequently, the weld’s heat-affected zone (HAZ)

receives the patented Tuff-Weld® process.

Tuff-Weld is a post-weld quenched and tempered heat treatment

of the heat-affected zone. The weld zone is heated by induction

to the specified austenitizing temperature, which is followed by

quenching from precisely positioned fluid nozzles. To ensure that

complete tempering is obtained, an area wider than the HAZ is

reheated to the proper tempering temperature by the induction

coil. A full 100% of welds that undergo the Tuff-Weld process are

subjected to hardness testing. The benefits of the Tuff-Weld

process are shown to the right by comparing the two weld zone

photomicrographs.

This photomicrograph depicts a typical normalized and tempered weld zone. The weld line is clearly evident by the contrasting microstructures of the tool joint and the tube upset. The microstructure of the higher carbon tool joint contains predominantly ferrite and pearlite, while the upset is often pearlite and has lower transitional constituents.

This photomicrograph depicts the typical microstructure of a Tuff-Weld® weld zone. The similar microstructures of the tool joint and the tube upset make the weld line difficult to detect. Both display tempered martensitic microstructures. The result is yield strengths and Charpy impact values superior to those of normalized microstructures. The Tuff-Weld process consistently produces stronger, tougher and more uniform weld zone properties. This combination of strength and toughness enhances fatigue resistance, making the Tuff-Weld process the most desired post-weld heat treatment in the industry. More than 50% of the drill pipe in the world is produced using the Tuff-Weld process.

DRILL PIPE

Automatic customized inline lathes simultaneously remove the

internal and external ram’s horns. Programmable sanding units

provide a surface finish that is free of stress risers. State-of-the-art

electromagnetic and ultrasonic inspections ensure that weld

inclusions and defects are not present.

Completed drill pipe assemblies undergo an intense inspection

process including a magnetic particle end area inspection, a

full-length Truscope® analysis, high-speed full-body ultrasonic and

electromagnetic inspection for longitudinal and transverse defects

and minimum wall thickness verification.

Induction heating and pressurized fluid quench are used in the patented Tuff-Weld® post-weld heat-treating process. The resulting quenched and tempered microstructure maximizes weld area properties.

TraceabilityDrill pipe assemblies are produced by welding pin and box tool

joints to an upset and heat-treated drill pipe tube. Material and

process traceability are maintained for each of the three compo-

nents. Mill material certifications for tool joints are confirmed by

incoming testing and each tool joint blank is given a unique heat

code. This code is traceable through the manufacturing process.

A Grant Prideco number is similarly used to provide traceability for

the drill pipe tube. The number is die-stamped for permanent

identification.

The MTI400VX weld line system is fully automated and features a computerized process, robotic control and laser positioning system.


DRILL PIPE

eXtreme® Drilling V-150™ Grade Drill PipeV-150 is a proprietary drill pipe grade offered by Grant Prideco for

applications that require ultra-high strength material. V-150

incorporates proprietary chemistry and a rigidly controlled

quench-and-temper heat treatment. The increased yield strength

provides superior torsional and tensile strength and enhanced

internal and collapse pressure integrity.

TSS™ Tough Sour Service 95 and 105 Grade Drill Pipe TSS™-95 and TSS™-105 drill pipe are proprietary grades offered

by Grant Prideco for service in H2S environments. With a unique

chemistry and a specialized quenched and tempered heat treat-

ment, TSS-95 and TSS-105 have optimum fracture toughness,

controlled yield strength and restricted hardness. The tubes are

NACE Method A tested to a threshold stress of 85% and 70%

respectively of the Specified Minimum Yield Strength (SMYS).

TSS-95 and TSS-105 have API tool joints and are best suited for

environments having lower H2S concentrations. Because its

minimum fracture toughness is 100 ft-lbs, TSS-95 drill pipe is ideal

for more demanding drilling applications, such as those with high

bending loads and corrosive environments.

Grant Prideco Proprietary Drill Pipe GradesIn addition to all API grades, Grant Prideco produces drill pipe in

several proprietary grades including high-toughness, high-strength

and sour-service grades designed for the most challenging

applications in the most severe environments.

S-135T™ Enhanced Toughness 135 Grade Drill Pipe S-135T™ drill pipe is a proprietary grade offered by Grant Prideco

for applications that require high strength and high toughness.

S-135T drill pipe incorporates a proprietary chemistry and a rigidly

controlled quenched and tempered heat treatment. The minimum

average specified Charpy impact energy is 59 ft-lbs for a 3/4 size

specimen at -4ºF, a 48% increase in impact energy over the

standard API S-135 grade. The performance behavior resulting from

this increase in toughness provides a margin of safety superior to

normal high-strength materials.

eXtreme® Drilling Z-140™ Grade Drill PipeZ-140™ is a proprietary drill pipe grade offered by Grant Prideco,

which is designed specifically for extreme drilling conditions

present in high temperature high pressure (HTHP) environments,

extended reach drilling (ERD), deepwater and ultra-deep wells.

Through proprietary steel chemistry and a rigidly controlled

quench-and-temper process, Z-140 drill pipe provides an excep-

tional balance between elevated strength and low-temperature

high-toughness requirements. Compared to standard API S-135

grade drill pipe, Grant Prideco’s Z-140 drill pipe grade provides a

higher minimum yield strength, a smaller window between

allowable minimum and maximum yield strength values and

increased toughness requirements to perform under the most

demanding cyclic loading operations.

The 5 inch 19.50 lb V-150™ drill pipe provides an 11% increase over S-135 in comparison to all standard API S-135 drill pipe in both tensile and torsional strength.

DRILL PIPE

5-7/8 inch eXtreme® Reach (XR™) Drill Pipe XR™ drill pipe was developed with a 5-7/8 inch diameter for

extended reach drilling (ERD) and ultra-deep wells. This intermedi-

ate size is ideal for hydraulic performance, high strength and ease

of handling, and represents a logical intermediary drill pipe size

between standard 5-1/2 inch and 6-5/8 inch drill pipe. Grant

Prideco offers 5-7/8 inch XR drill pipe in all standard API material

grades and proprietary grades including high toughness, high

strength and sour service grades. Tool joints can be configured to

accompany any rotary-shouldered connection.

Operational Advantages of 5-7/8 inch XR™ Drill Pipe 5-7/8 inch drill pipe provides

enhanced hydraulic performance compared to 5-1/2 inch drill

pipe for ERD and ultra-deep well applications.

5-7/8 inch drill pipe utilizes

a 7 inch OD TurboTorque ™ or XT® tool joint, allowing it to be

used to drill inside 9-5/8 inch casing and 8-1/2 inch open-hole

sections. Overshot fishing capability in an 8-1/2 inch hole is

maintained.

XR eliminates the need for 6-5/8 inch drill pipe,

which is difficult to handle and can sacrifice rig space and

setback capacity because it cannot be used to drill 8-1/2 inch

hole sections.

5-7/8 inch drill pipe minimizes rig

modifications in comparison to 6-5/8 inch drill pipe.

CONNECTIONS



For more than 25 years, Grant Prideco has been the leader in the development of rotary-shouldered connections. A long-standing workhorse of the industry, the HI-TORQUE® (HT™) connection provides approximately 40% more torque than

comparable API connections.

With an improved thread form and a flatter taper, Grant Prideco’s

second generation eXtreme® Torque (XT®) connection meets the

needs of deep, extended reach and HTHP wells, providing even

more torque, a reduced profile and improved hydraulics. eXtreme

Torque (XT®) connections often allow the use of a larger pipe size

for a given hole size while maintaining fishability.

The eXtreme® Torque Metal Seal (XT-M™) connection is the

industry’s first pressure-rated, gas tight rotary-shouldered

connection. eXtreme® Torque XT-F™ and XT-MF™ offer XT and

XT-M performance with a special fatigue-resistant thread form

for the most severe drilling applications.

Released in 2002, the Grant Prideco Double Shoulder® (GPDS™)

connection provides nearly the torque of the HI-TORQUE connection

with the convenience of interchangeability with the comparable

API connection.

Grant Prideco’s third generation TurboTorque™ (TT™) connection

was introduced in 2006. TurboTorque features a double start thread

form, reduced connection profile and multiple design configura-

tions to meet specific drilling requirements. The results are

optimized torque capacity and hydraulics, improved clearance and

fishability, extended life and reduced risk of failure.

Grant Prideco’s latest development is the gas-tight, pressure-

rated TurboTorque-M™ (TT-M™), featuring all of the benefits of

TurboTorque connections, with the added advantage of an

advanced metal-to-metal seal.

How to Select Rotary-Shouldered Connections


Selection of a rotary-shouldered connection is determined by torque capacity and

profile requirements. There is a trade-off between these requirements. As you

progress from left to right and bottom to top, Grant Prideco connections provide

greater torque with a slimmer profile.

Rotary-Shouldered ConnectionLeading the industry, Grant Prideco has further refined the

development and optimization of rotary-shouldered connection

design with the TurboTorque™ connection. TurboTorque is the

industry’s first rotary-shouldered connection that is composed of

four distinct configurations, optimized to best meet the specific

and differing needs of each individual pipe size (see chart on next

page).

The patented TurboTorque connection is the industry’s highest

performance connection available in sizes for 2-3/8 inch through

6-5/8 inch drill pipe and provides the following benefits:

Double-Start Thread TurboTorque™ connections are the industry’s first rotary-

shouldered connections to offer a double-start thread form. Dual

threads, 180 degrees apart, reduce the number of turns from stab

to makeup by 50%, saving significant rig time. The resulting

increase in thread lead angle provides an increased torque capacity

of 12%.

2-6


Stronger Tool Joints Standard drill pipe tool joints are made of steel with Specified

Minimum Yield Strength (SMYS) of 120,000 psi (120 ksi SMYS).

Historically, efforts to increase the

tool joint yield strength have resulted

in reduced fracture toughness and

increased susceptibility to fatigue

crack propagation. TurboTorque

connections are engineered specifi-

cally for use with 130 ksi SMYS tool

joints, meeting the increased fracture

toughness required by API and

proprietary manufacturing standards

such as NS-1™, DS-1™ and NORSOK. In

addition, the TurboTorque thread

form and tool joint geometry have

been engineered to provide industry-

leading fatigue performance. The result is a rotary-shouldered

connection with increased torque capacity, reduced connection

profile, greater fishability and increased hydraulic performance.

Increased Torque Capacity TurboTorque connections provide more torque capacity than any

other double-shouldered connection in the industry today, and the

“torque on demand” feature provides an additional 8% of torque

capacity for those unusual drilling situations.

Three make-up torque (MUT) values are provided for each

TurboTorque connection:

Minimum torque is the least amount of MUT acceptable to ensure

that the connection will function properly. Minimum MUT is

normally only considered in cases when the recommended MUT

may exceed capacity of the rig equipment, such as large diameter,

high-strength drill strings or landing strings.

Recommended MUT is used for normal drilling operations. In most

situations, it provides enough torque to prevent downhole makeup

while minimizing connection stress.

TurboTorque connections are the first in the industry to provide a

Turbo-MUT. Also known as “torque-on-demand”, Turbo-MUT

provides an additional 8% of torque capacity for those unusual

drilling situations when additional torque is required. Most of the

testing and design validation for the TurboTorque family were

conducted on connections made up to the Turbo-MUT value.

Extensive testing allows the Turbo-MUT to be used confidently

without having to consult Grant Prideco.

Optimized Connection Taper Taper is the controlling factor in the final configuration of a

rotary-shouldered connection. The TurboTorque taper is engineered

to ensure a balance between the pin and box, maximizing

connection stiffness and fatigue resistance. The taper is designed

to deliver maximum tradeoff between tensile strength, torque

capacity and connection profile. The result is a balanced pin and

box, reduced connection profile, connection stiffness and fatigue

resistance, greater fishability, increased hydraulic performance and

optimum balance between all performance parameters.

Optimized Hydraulic PerformanceThe refinement of the TurboTorque design and 130 ksi SMYS tool

joints mean the tool joint ID can be increased for diminished

pressure loss through the drill string. In comparison to Grant

Prideco’s XT® connection, tool joint ID can often be increased

1/8 of an inch or more. For a given hole size, TurboTorque’s slim

outside diameter often permits the use of a larger pipe size, which

significantly increases hydraulic performance. More hydraulic

horsepower at the bit saves operational cost and enables drilling

of deeper wells.


High–Performance Thread FormTurboTorque’s thread height is optimized for each of the four design

configurations. The thread form incorporates a unique dual-root

radius, larger than the root radii of API and even XT® connections,

significantly reducing the connection peak stress.

Save Time, Cut CostsA TurboTorque connection requires the same running procedures

as the XT connection. However, TurboTorque’s double-start thread,

faster taper and deeper stabbing greatly reduces the turns to

makeup. The resulting time saved has a marked effect on rig

economics. Compared to competitive premium rotary-shouldered

connections, TurboTorque connections often pay for themselves on

the first well, then continue to provide operational savings.

Enabling Technology – Drill Deeper, Faster, FurtherThe TurboTorque connection’s torque capacity exceeds that of all

double-shouldered connections on the market. Its slim profile

decreases pressure loss through the tool joint and often allows the

use of a larger pipe size. The result: more mechanical and hydraulic

horsepower at the bit, enabling completion of world class wells.

Reduced Total Cost of OwnershipHigh-strength and high-toughness tool joints and a unique

dual-radius thread form have pushed the fatigue resistance of

TurboTorque connections far beyond previous industry limits. In

addition, TurboTorque connections combined with superior Grant

Prideco technology including engineered materials, quenched

and tempered weld zones, fatigue-resistance upset/weld-neck

geometry, quality processing and Platinum® hardbanding, are

proven to extend life, increase reliability and reduce total cost

of ownership.

ConnectionGrant Prideco’s latest rotary-shouldered connection is the result of

an ongoing two year comprehensive design, test and qualification

effort. The TurboTorque-M™ connection incorporates a radial,

metal-to-metal, internal pressure seal, providing all of the benefits

of the industry’s highest performing TurboTorque™ connection with

the added security of a gas-tight pressure sealing capability.

The internal metal seal is generated by radial interference, reducing

the effects of tensile load. Capable of resisting high-pressure liquids

and gas, the seal integrity is not affected by multiple trips.

All sizes of the TurboTorque-M connections are pressure rated at

20,000 psi internal and 10,000 psi external. ISO13679 testing

methodologies for casing and tubing were modified to validate

the connection’s pressure capability under harsh, aggressive,

dynamic loads.

TurboTorque-M drill strings can be used for drill stem testing

operations, high-pressure workover and completion operations,

and underbalanced drilling operations. The TurboTorque-M drill

string eliminates the need for a separate work string, which

ultimately saves time, money, rig space and deck load.


Radial Metal-to-Metal Seal

Connection




In addition to providing a 20,000 psi internal and 10,000 psi

external pressure rating, TurboTorque-M™ connections provide

increased mechanical and hydraulic performance compared to

eXtreme® Torque-M™ (XT-M™) connections, while also providing

fatigue performance greater than standard API connections. In

comparison with XT-M, TurboTorque-M provides a 1/4 inch larger

ID for increased hydraulics, 8% additional working torque capacity

and 5,000 ft/lbs of additional rated internal working pressure

(see table).

TurboTorque-M connections are not interchangeable with any

other rotary-shouldered connection, including TurboTorque™

connections.

Rotary-Shouldered Connection The patented eXtreme® Torque (XT®) connection addresses the

requirements of many extreme drilling applications, including

extended reach drilling (ERD), horizontal drilling, deepwater, high

temperature high pressure (HTHP) and ultra-deep wells.

High-Performance DesignThe eXtreme Torque connection is a patented, high-performance,

rotary-shouldered connection available in sizes from 2-3/8 inch

through 6-5/8 inch drill pipe. The eXtreme Torque connection

incorporates a second generation double-shouldered design. A

secondary internal torque shoulder on the nose of the pin offers an

additional friction surface and mechanical stop. The primary

external shoulder still serves as the connection’s sealing surface.

The eXtreme Torque connection design has an extended pin base,

pin nose and box counterbore. These sections are carefully

engineered to provide additional elastic deformation during

makeup, ensuring that the contact forces are properly proportioned

between the two shoulder surfaces.

Increased Torque CapacityThe XT connection offers significantly higher torsional capacity

than standard API connections, as well as Grant Prideco’s GPDS™

and HI-TORQUE™ connections. This additional capacity provides the

required torque for the most extreme drilling applications.




Slim ProfileThe XT® connection’s increased torsional strength allows for the

use of a streamlined tool joint that is sized for the pipe’s torsional

strength. XT connections can be configured with a smaller OD and

larger ID compared to standard API connections without sacrificing

torsional capacity. Often, XT connections permit the use of a larger

diameter drill pipe, providing improved hydraulic efficiency, better

hole cleaning and greater buckling strength for horizontal and

extended reach applications without sacrificing torsional strength

or fishability.

True Flush Inside DiameterThere is no gap or change in the inside diameter from the box to

the pin, creating a smoother flow with less turbulence. This feature

also eliminates the recess found in standard connections where

cement and solids can be trapped.

Rugged DurabilityThe robust XT connection design incorporates more steel in the

critical areas of the connection resulting in less refacing and fewer

recuts. In addition, because of the increased torsional capacity, the

XT connection greatly extends the life of the joint by tolerating

more OD wear.

Field RepairableThe XT connection can be refaced in an inspection yard or at the rig

site with a portable refacing tool. This flexibility can save time and

expenses by eliminating transportation and handling costs.

User FriendlyXT connections utilize the same running procedures as standard

API connections. The connection spins up freely until shouldered,

then is bucked up to the make-up torque. XT connections have a

more shallow taper, requiring a more shallow stab and slightly

more turns to makeup.

Rotary-Shouldered Connection The patented XT-M™ connection is the industry’s first gas-tight,

pressure-rated rotary-shouldered connection. An eXtreme™ Torque

connection with a radial metal-to-metal internal pressure seal,

XT-M provides torsional strength comparable to XT® connections

combined with a gas-tight pressure sealing capability.

The gas-tight seal is generated by radial interference, reducing the

effects of tensile load. Capable of resisting high-pressure liquids

and gas, the seal integrity is not affected by multiple trips.

All sizes of the XT-M connections are pressure rated at 15,000 psi

internal and 10,000 psi external.

XT-M drill strings can be used for drill stem testing (DST) opera-

tions, high-pressure workover and completion operations, and

underbalanced drilling operations. An XT-M drill string eliminates

the need for a separate work string, which saves time, money and

rig space.

XT-M connections are not interchangeable with any other rotary-

shouldered connection, including XT connections.

The Grant Prideco Double Shoulder™ (GPDS™) connection is a

high-performance, rotary-shouldered connection available for

2-3/8 inch through 6-5/8 inch drill pipe. GPDS connections offer

a versatile alternative to standard API connections where higher

torsional strength is required and are interchangeable with API

connections.

Increased Torsional CapacityThe double-shouldered design of GPDS provides increased torsional

capacity when compared with similar sizes of API connections.

A secondary internal shoulder on the nose of the pin offers an

additional friction surface and mechanical stop. The primary

external shoulder still serves as the connection’s sealing surface.

Slimmer ProfileGPDS connections can be configured with a smaller OD and larger

ID compared to standard API connections, improving fishability and

hydraulic efficiency without sacrificing available connection

torsional capacity.

True Flush IDThe GPDS double-shouldered design provides a true flush inside

diameter throughout the mated tool joint assembly, thereby

minimizing turbulent flow, improving ID tool passage and

eliminating opportunities for cement and solids to be trapped.

Increased Allowable Tool Joint WearGPDS connections offer higher torsional capacity than standard

API connections of the same dimensions, thereby increasing

permissible connection wear prior to downgrading the assembly


2-20


to Class 2. For example, an NC50 on 5 inch 19.50 lb S-135 drill pipe

is downgraded to Class 2 when the OD wears below 6-5/16 inches.

At this diameter, the tool joint is less than 80% as strong as

Premium Class pipe. The GPDS50 connection can tolerate wear

down to a diameter of 5-3/4 inch before its torsional strength falls

below 80% of the pipe strength.

The Grant Prideco Drill Collar (DC™) connection provides a step

change in BHA connection performance. The enhanced connection

is ideally suited for drilling programs plagued with aggressive drill

string dynamics (axial, lateral and torsional vibrations), H2S

environments and wells equipped with The IntelliServ® Network.

A New Paradigm in Fatigue Resistance The DC connection features a unique fatigue

resistant thread form that incorporates a generous

dual thread root radius of 0.060 inch and 0.065

inch. The larger dual-root radius significantly

reduces peak stresses in the thread root and

extends connection fatigue life. The DC connection

pins also include a stress relief feature. Laboratory

test results indicate that the DC58 connection

provides a near full order of magnitude increase in

fatigue performance, at least nine times improved,

compared to API 6-5/8 inch Regular connection.


CONNECTION S-N COMPARISON†


Improved Make-Up Efficiency Compared to API Regular connections, the DC™ connection stabs

deeper and makes up with fewer turns. DC™58 connections have

three threads per inch and a steeper three-inch-per-foot taper.

Three revolutions are required to make up the DC58 connection,

compared to six revolutions with a 6-5/8 inch API Regular

connection. DC58 field trials verified improved make-up

efficiency and exceptional post-field trial inspection results.

Workable Make-Up Torque For larger sizes, the normally high makeup torque of double-

shouldered connections often tests the limits of rig equipment.

DC connections are designed to have make-up torques similar

to the requirements of the API counterpart connection.

IntelliServ® Network Compatible In order to complete a telemetry network from the bit to the

surface, DC™ double-shouldered drill collars provide an ideal

location for the IntelliServ induction coil placement, with each coil

installed in a protective groove in the secondary torque shoulder.

Minimal Recut Loss The steeper taper of the DC connection reduces loss from recutting

the connections. Compared to the API 6-5/8 inch Regular connec-

tion, the DC58 connection saves just over one inch of material after

each pin recut, and just over 1/2 inch after each box recut.

Resistant Thread ConnectionsThe SST® and SRT® connections are proprietary connections that

provide increased durability and fatigue resistance compared to

a standard API connection.

The SST connection involves a modification to the pin thread

only; the mating box thread remains standard. Completely

interchangeable with the standard API connections, the SST

connection requires no crossovers or special rig handling

procedures. The SST pin incorporates two primary features. First,

the thread form has an enlarged root radius grooved into the

slab flank. Second, the pin thread body is machined on a slightly

flatter taper than that of the box, effectively behaving like a

variable pitch thread.

The SRT connection involves a modification to the box thread

only; the mating pin thread remains standard. Completely

interchangeable with the standard API connections, the SRT

connection requires no crossovers or special rig handling

procedures. The thread form has an enlarged root radius

grooved into the slab flank.
