DRILL PIPE

Drill Pipe Design and Manufacturing

Design

Drill 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

Geometry

The 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 Processing

Grant 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 Processing

Grant 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

Welding

A 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.

Traceability

Drill 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 Pipe

V-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 Grades

In 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 Pipe

Z-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.

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 Connection

Leading 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 Performance

The 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 Form

TurboTorque’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 Costs

A 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, Further

The 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 Ownership

High-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.

Connection

Grant 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™

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 Design

The 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 Capacity

The 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 Profile

The 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 Diameter

There 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 Durability

The 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 Repairable

The 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 Friendly

XT 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.

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 Capacity

The 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 Profile

GPDS 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 ID

The 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 Wear

GPDS 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.

DC CONNECTION MECHANICAL CHARACTERISTICS†



Resistant Thread Connections

The 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.

The patented benchmark provides a reference for dressing the

tool joint’s make-up shoulders. As shown in the adjacent figures,

a 1/8 inch wide step is machined onto the pin base adjacent to the

torque shoulder. Similarly, a 1/8 inch wide step is machined onto

the box counterbore adjacent to the box make-up shoulder. Unlike

the API “tangent bar,” this step provides a reference that is visible

from any position around the connection’s circumference.

The amount of remaining material available for dressing can be

easily determined with a pocket scale. The benchmarks are

machined by the CNC machine tool during the threading process.

This feature results in an accurate placement of the reference

surface.

By placing a refacing benchmark on the external bevel

of the connection, the Xmark™ benchmark allows a

simple determination to be made as to how much

space is remaining to reface the connection prior to

recutting. Available on many new connections

furnished by Grant Prideco, Xmark is the clear solution

to refacing limit uncertainty, and the only practical

method of applying benchmarks to connections

having stress relief grooves, such as drill collars and

heavyweight drill pipe.

Refacing benchmarks show the position of the original

shoulder so the inspector can estimate the amount of

refacing a connection has undergone and determine if

excessive refacing has occurred. An advantage of Grant

Prideco’s proprietary Xmark benchmark is that it

reveals not only the extent of refacing, but also how

perpendicular the refaced seal is to the pipe axis.

Xmark’s user-friendly design eliminates both the measurement and

the math. Because Xmark is visually detectable throughout the full

Care and handling procedures for specific Grant Prideco connec-

tions are available on our website at www.GrantPrideco.com. The

following procedures outline recommended practices for all Grant

Prideco drill pipe.

1. Check to ensure the counter-balance on the top drive is

working properly and provides a minimum amount of weight

applied to the connection during make-up operations. If the

top drive counter-balance is not working or is adjusted

incorrectly, too much weight will be applied to the connec-

tion during make-up and may cause connection damage. To

make adjustments to the top drive counter-balance system,

contact the top drive manufacturer for proper counter-

balance adjustment procedures.

2. Because some sizes of the TurboTorque™, TurboTorque-M™,

XT® and XT-M™ connections have slower tapers than

HI-TORQUE®, GPDS™ or standard API connections, increased

effort regarding pin to box alignment during stabbing

operations is required.

3. Visually inspect pipe and tool joints for damage. If thread

protectors are damaged, remove and visually inspect

connections.

4. If pipe is picked up with handling plugs, check the plugs

for damage before making them up in the drill pipe box

connections. Keep protectors on the handling plugs when

they are lowered down the V door, and until they are screwed

into the box connections.

5. Leave the pin protectors on the pipe as it is pulled up the

V door and when the pipe is lowered into the mouse hole.

Only remove after it is pulled out of the mouse hole.



6. Break in the top drive saver sub by making it up and breaking

it out to the recommended MUT three times in the rotary

table before it is made up in the top drive. Use a short saver

sub (5-1/2 inches shoulder to shoulder). This will position the

pipe handler torque wrench two inches below the box

shoulder, so it will not crush the counterbore of the box

connection.

7. Stab in the top joint near the rig floor so you can verify that

the pin is centered in the box.

8. Check the top drive torque and iron roughneck torque with

the rig tongs and a recently calibrated load cell to make sure

the correct torque is being applied to the connection. Check

break-out torque to make sure it is not more than make-up

torque.

9. Grant Prideco requires the use of a stabbing guide when

stabbing any TurboTorque-M™ or XT-M™ connection, and

recommends its use for other connections as well. Use of a

stabbing guide: (1) ensures proper pin to box alignment and

reduces stabbing damage to the box seal face, (2) increases

safety by reducing opportunities for finger pinch points when

handling the connection and (3) may actually increase trip

times by reducing time spent by the rig crew when aligning

pin to box connections during tripping operations. Stabbing

guides are available in many types (plastic and stainless

steel) and sizes as shown in the pictures below. The use of a

stabbing guide is NOT required, nor recommended by Grant

Prideco when breaking out connections.

2-40


10. Ensure the use of contaminant-free thread compound and

proper doping procedures. Standard thread compounds

generally used with rotary-shouldered connections such as

zinc-based, copper-based, Teflon®-based and other metal

and metal-free thread compounds are compatible with Grant

Prideco connections. Based on in-house testing and field

experience, Grant Prideco has seen more consistent friction

properties for copper-based thread compounds.

11. Proper alignment, along with slow initial makeup of the

starting threads, is critical. Caution is required in making

up the first five or six threads before spinning it up. If the

connection is made up with misalignment and fast spin

up, minor thread damage may occur within the starting

threads. Should this happen, it can be removed with a soft

grinding wheel or a file. This will not be detrimental to the

connection.

12. When pipe is laid down, ensure thread protectors are

installed.

Hardbanding has been used in the oil and gas industry for

decades. Through years of research and testing, Grant

Prideco has developed some of the industry’s top solutions.

Several hardbanding options are available to meet your drilling

challenges.

Platinum® HB Hardband

Two years of continuous research, development and testing have

resulted in Platinum HB, the industry’s first engineered hardband

solution. Introduced to the market in 2006, Platinum HB delivers

best-in-class tool joint protection in casing, superior resistance to

spalling and cracking, industry-best casing protection and easy

reapplication over itself, with the convenience of a cost-effective

single-source supplier.

SmoothX™ Hardband

A patented hardband of submerged spherical tungsten carbide

granules in a mild steel matrix, SmoothX provides a smooth surface

with little or no exposed carbide.

Grant Prideco can provide other commercial hardbands upon

request.

HARDBANDING

Platinum® HB

Engineered specifically for drill string hardbanding applications,

Platinum® HB provides minimum casing wear while maintaining

excellent tool joint protection. Today’s severe wear environments of

extended reach, horizontal, deepwater and abrasive hard rock are

easily handled by Platinum HB, making it the ideal choice of both

oil companies and pipe owners for a complete range of drilling

applications. Platinum HB’s near-nanoscale microconstituents offer

a new paradigm of both high strength and high toughness.

Platinum HB provides unsurpassed wear characteristics while

maintaining the impact resistance and toughness necessary to

resist spalling and flaking downhole.

Superior Resistance to Cracking

Through a patent-pending application process, Platinum HB has

been meticulously engineered to contract and expand at the same

rate as the tool joint steel to virtually eliminate cracking during

application and in the field. Other hardbands have traditionally

reduced their strength and hardness to achieve a crack-free

application, consequently sacrificing tool joint protection. Matching

the Coefficient of Thermal Expansion (CTE) of the hardband

material and base tool joint steel enables higher strength and

hardness without detrimental cracking tendencies. Platinum HB’s

high strength and high toughness provide a

wear-resistant hardband with superior

resistance to cracking and spalling. Dye

penetrant testing of applied hardband

materials proves the superior crack resis-

tance of Platinum HB relative to competitive

hardbands (see photos at right).

Platinum® HBCompetitor

Best Casing Wear

The near-nanoscale microconstituents of Platinum HB deliver the

industry’s absolute best casing protection. Casing wear tests

conducted at Grant Prideco’s Technology Center show a 37%

reduction in casing wear over the nearest “casing-friendly”

competitor (see graph on next page). Grant Prideco is the only

hardband manufacturer to purchase, install and operate its own

casing wear test machine (see photo above). Throughout the

Platinum HB development program, hundreds of samples were

tested including most competitive casing-friendly hardbands.

BEST CASING WEAR

37% improvement in casing wear performance compared to the nearest competitor

Best Tool Joint Wear

Platinum HB not only minimizes casing wear, it provides signifi-

cantly better tool joint protection than any other casing-friendly

hardband product on the market. This fact has been proven in

comparative tests against the leading hardband solutions currently

available in the industry. The results show a 55% improvement in

radial tool joint wear of casing compared to the second best

solution (see graph below left). With Platinum HB, you get

maximum tool joint protection with no compromise in casing wear

performance, a feat never before achieved by any other hardband.

Re-Application

When considering the long-term cost of drill pipe ownership,

re-application of the hardband is an important consideration. Many

of the unique properties that result in Platinum HB’s superior field

performance also contribute to its ease of re-application. The

“matched” CTE, strength, toughness and virtual elimination of

cracking of Platinum HB permit this hardband to be economically

applied over itself.

Single-Source Convenience and Accountability

Grant Prideco’s global operations, innovative products and

sophisticated testing laboratories meet the demands of the

toughest drilling challenges. Product quality and performance

are optimized by Grant Prideco’s vertical integration from mill to

market and by a complete offering of drill pipe, tool joints and

related drill stem products, all specifically engineered to comple-

ment each other. Platinum HB provides the convenience of

single-source ordering, logistics and accountability. Grant Prideco

provides quality control from raw material source through final

inspection.

SmoothX™ Hardbanding

SmoothX™ hardbanding was developed to minimize tool joint

wear. Five bands of the SmoothX hardbanding are applied around a

tool joint, covering approximately 3-1/2 to 4 inches of length. Three

“fingers” of SmoothX hardbanding are applied to the elevator

shoulders to prevent wear and undercutting adjacent to the last

band of hardbanding in open-hole environments. Without these

fingers, erosion of the elevator shoulder could occur, shortening the

life of the tool joint.

Spherical carbide granules in a mild steel matrix

SmoothX™ tool joint with fingers

SmoothX hardbanding is applied in a machined groove on the

tool joint by dropping a measured quantity of spherical, sintered,

30-14 mesh tungsten carbide granules into a molten puddle

formed by welding wire. The granules sink into the molten weld

metal and leave a smooth surface that has little or no exposed

tungsten carbide. The resulting matrix has an increasing density of

tungsten carbide from the surface to the bottom of the deposit.

HARDBANDING

SmoothEdge® Tool Joints

Grant Prideco’s SmoothEdge® tool joints provide a sacrificial wear

pad for the installation of tool joint hardbanding. SmoothEdge is

available for both pin and box tool joint hardbanding applications,

and is width and height adjustable to allow for customer-specific

hardbanding applications. Use of SmoothEdge tool joints and

casing-friendly hardbanding extends the life of the tool joint,

reduces torque and drag operating loads and significantly reduces

casing wear.

Reduced Risk to Downhole Pressure-Sensitive Components

Often, the leading edge of proud hardbanding applications can be

sharp or jagged, increasing wear or damage to various downhole

components. Grant Prideco’s SmoothEdge tool joint provides a

base material with a radius as the leading edge to the hardbanding

material. The radius reduces wear and tear to items such as seals

within rotating heads and other items whose pressure integrity

are critical, especially within pressure-critical operations such as

underbalanced drilling (UBD) and managed pressure drilling (MPD).

Improved Hardbanding Integrity

Initial Application – Proud hardbanding applications ideally

maintain higher weld bead heights than other applications. The

significant amount of bead deposit required to achieve these levels

often makes the initial application of casing-friendly hardbanding

susceptible to flaking and spalling. Grant Prideco’s SmoothEdge

tool joint provides an expendable wear pad allowing a more

controlled weld bead deposit while maintaining proud application

heights desired to protect the tool joint from wear.

TurboTorque™ tool joints with SmoothEdge® feature are ready for hardband application.

Re-application – Re-application of casing-friendly hardbands are

also susceptible to flaking and spalling, largely because they are

designed to weld to a crack-free, base steel metal. However, most

casing-friendly hardbanding re-applications are made over the

existing hardbanding, promoting the probability of hardband

cracking, spalling and loss of material integrity. Grant Prideco’s

SmoothEdge® tool joints provide an elevated sacrificial wear pad

such that the initial hardbanding material can wear down to the

tool joint material itself. This feature allows a re-application to be

made again on the tool joint’s crack-free, base steel material.

Grant Prideco offers three types of Heavyweight Drill Pipe

(HWDP). Designed to provide a gradual transition between

drill pipe and drill collars, HWDP improves the fatigue

resistance of the drill string.

Standard HWDP is suited for most applications including vertical,

extended reach and horizontal wells.

Grant Prideco’s Tri-Spiral™ HWDP is suited for applications requiring

additional hole-cleaning and buckling resistance.

Spiral-Wate® HWDP reduces differential sticking, minimizes wear

and improves circulation in especially tough drilling environments.

HEAVYWEIGHT DRILL PIPE

5-2


Standard HWDP

Standard Heavyweight Drill Pipe (HWDP), was developed to provide

a gradual transition from heavy drill collars to relatively lightweight

drill pipe. This intermediate weight pipe has a wall thickness of

approximately one inch, and helps prevent stress concentration at

the top of drill collars. HWDP also allows drilling at higher RPMs,

reducing torque and differential pressure sticking.

HWDP is well-suited for directional drilling. Because it bends easily,

it simplifies directional control and minimizes connection fatigue

problems common to high-angle or horizontal drilling.

For extended reach and horizontal wells, especially in wells where

the total vertical depth to total measured depth ratio is low, high

strength heavyweight drill pipe is often used high in the hole to

apply weight on the bit.

Various combinations of HWDP, drill collars and standard drill string

components can be created to meet the challenges of severe

drilling conditions.

Tri-Spiral™ HWDP

Grant Prideco developed Tri-Spiral™ Heavyweight Drill Pipe for

extended reach and horizontal drilling applications requiring

greater buckling resistance and hole cleaning than is available with

standard HWDP. The severe bending stresses and hole/wall contact

are reduced by three spiral upsets that are equally spaced between

tool joints. The upset design helps reduce buckling and differential

sticking, as well as torque and drag. Spiraling the upsets also helps

move the cuttings off the low side of the hole for better hole

cleaning.

Tri-Spiral HWDP features more weight per joint and better hole

cleaning characteristics than standard heavyweight drill pipe,

providing optimum performance in severe drilling conditions.

Spiral-Wate® HWDP

Spiral-Wate® drill pipe, spiraled heavy-wall drill pipe, is designed to

handle maximum stress to save time and reduce drilling costs,

especially in tough drilling environments.

Intermediate drill string members are constantly subjected to some

of the most severe tasks in drilling today. The critical transition

zone between stiff, heavy drill collars (under compression) and

the light, more flexible drill pipe (in tension) is critical to the

performance of the drill string.

Spiral-Wate drill pipe’s unique patented spiral design reduces

differential sticking problems, minimizes wear and improves

circulation. Precision tool joint alignment cuts down on excessive

tool joint wear for longer service life and reduced fatigue.

Features and Options

Extra-Long Tool Joints

Grant Prideco heavyweight drill pipe is manufactured by welding

extra-long tool joints to heavy-wall tubes. The extra-long tool joint

increases tong space, and allows for several connection recuts to

maximize your investment.

Cold Rolling

Heavyweight drill pipe undergoes repeated severe tensile and

compressive stresses during the drilling operation. As compared to

regular drill pipe, HWDP is much stiffer, focusing cyclic stresses on

the thread roots and potentially resulting in connection failure. To

help alleviate this problem, the thread roots on every piece of

heavyweight drill pipe are cold-rolled by Grant Prideco. Cold rolling

imparts an initial state of compressive stress that minimizes crack

initiation thereby increasing fatigue resistance.


Phosphate Coating

All heavyweight drill pipe connections are given a hot phosphate

coating to provide resistance to galling and corrosion.

Hardbanding

Grant Prideco has several hardbanding materials available to apply

to heavyweight drill pipe including Platinum® HB and SmoothX™,

as well as third-party materials. Hardbanding can be applied in

several configurations to meet specific needs.

Proprietary Rotary-Shouldered Connections

In addition to the API and public domain connections listed in the

previous tables, Grant Prideco can provide heavyweight drill pipe

with proprietary stress relief thread forms or double-shouldered

connections to enhance performance (see Rotary-Shouldered

Connections section).

The cold-rolling process consists of compressing metal fibers by means of a roller to increase fatigue resistance.



HWDP Grades

Standard Heavyweight Drill Pipe

Grant Prideco standard heavyweight pipe is manufactured from

AISI 1340 material and heavyweight tool joints are manufactured

from AISI 4142H-4145H modified drill collar material.

eXtreme® Drilling XD®-90 Sour Service Grade

eXtreme® XD®-90 HWDP is a proprietary product offered by Grant

Prideco for service in H2S environments. Available in both standard

and spiral designs, XD-90 heavyweight drill pipe provides higher

strength and a tempered martensite microstructure for enhanced

resistance to crack initiation and crack propagation. XD-90 HWDP

incorporates a proprietary chemistry and a rigidly controlled

quench-and-temper heat treatment process. The eXtreme XD-90 is

resistant to sulfide stress cracking and its high fracture toughness

is ideal for the most demanding drilling conditions, including

applications with high bending loads and corrosive environments.

eXtreme® HW™-95 and HW™-120 Heavyweight Drill Pipe

HWTM-95 and HWTM-120 high-strength heavyweight drill pipe are

proprietary grades offered by Grant Prideco for target applications

requiring the use of HWDP high in the hole where elevated tensile

and torsional loading is expected. Both HW-95 and HW-120 provide

high yield strength – 95 ksi and 120 ksi minimum, respectively,

a 73% and 218% increase in yield strength over standard

heavyweight products – resulting in superior tensile and torsional

strength properties. These pipe configurations provide tensile and

torsional capacities equal to or greater than nearly all types of

standard API drill pipes tubes. As a result of the increased strength,

HW-95 and HW-120 are a perfect fit for applications such as short

radius, horizontal and extended reach drilling projects where use of

HWDP above the kick-off point is required for applying bit weight

and additional buckling stability.

Grant Prideco Drill Collars are integral heavy-wall joints that

are manufactured from a solid bar of modified alloy steel.

The solid bars are quenched and tempered to obtain the

required mechanical properties, then trepanned, drifted and

threaded. Drill collars are furnished as slick or spiraled in 30 or

31 foot lengths.

Slick drill collars are supplied with the mill as-rolled surface finish.

Spiraled drill collars have grooves machined in the outside surface.

The spiral grooves promote even flow of drilling fluid around the

collar diameter, equalizing pressure and reducing the occurrence

of differential sticking.

Pony Collars

In order to adjust the length and control the placement of

components in bottom-hole assembly, Grant Prideco can provide

pony collars in 5, 10, 15 and 20 foot lengths. Pony collars can be

furnished in standard or non-magnetic material, and can be

customized to suit individual requirements with any of the

options offered for full-length collars.

RECOMMENDED MAKE-UP TORQUE AND BENDING STRENGTH RATIOS†

NOTES: † Please refer to page x of the Introduction. (1) Basis of calculations for recommended make-up torque assumed the use of a thread compound containing 40% to 60% by weight of finely powdered metallic zinc, or 60% by weight of finely powdered metallic lead, with no more than 0.3% total active sulfur (reference the caution regarding the use of hazardous materials in Appendix G API Spec. 7 Latest Edition), applied thoroughly to all threads and shoulders. Also, the modified screw jack formula was used, as shown in the IADC Drilling Manual and the API Spec. RP7G Latest Edition and a unit stress of 62,500 psi in the box or pin, whichever is weaker. Torque values are rounded to the nearest 100 ft-lb. (2) Normal torque range is calculated value plus 10%. Higher torque values may be used under extreme conditions.

NOTES (cont'd): (3) In each connection size and type group torque values apply to all connection types in the group, when used with the same drill collar OD and bore, i.e. 2-3/8 API IF, API NC26 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 4600 ft-lbs and the box is the weaker member. (4) Stress-relief features are disregarded for make up torque calculation. (5) H-90 connection make-up torque is based on 56,200 psi stress and other factors, as listed in note 7. (6) 2-7/8 PAC make-up torque is based on 87,500 psi stress and other factors, as listed in note 7. (7) Torque figures in bold indicate that the weaker member for the corresponding outside diameter and bore is the box. For all other torque values, the weaker member is the pin.

Pup Joints

Grant Prideco pup joints are manufactured from the same material

as Grant Prideco drill collars. Pup joints are trepanned from solid

bar, and heat-treatment processes ensure a hardness range of

285-341 Brinell. Charpy “V” notch minimum impact strength of

40 ft-lb at 70ºF are guaranteed one inch below the surface. The

integral drill pipe pups are heat-treated to 120,000 psi minimum

yield strength. These integral pups have the same tensile and

torsional rating of S-135 drill pipe with the same pin ID.

Standard lengths are 5, 10, 15 and 20 feet. Additional sizes are

available upon request.

When ordered with same-size drill pipe, pup joints 15 feet and

longer can be produced as welded assemblies.

In addition to API and public domain connections, Grant Prideco

can provide pup joints with proprietary SST® and SRT® stress relief

thread forms or double-shouldered connections (See Rotary-

Shouldered Connections section) for increased performance.

All connections are phosphate-coated to improve resistance to

galling.

Rotary Subs

Grant Prideco rotary subs are manufactured from the same

material as Grant Prideco drill collars. Subs are trepanned from

solid bar and heat-treatment processes ensure a hardness range

of 285-341 Brinell Hardness Number (BHN). Charpy “V” notch

minimum impact strength of 40 ft-lb at 70ºF are guaranteed one

inch below the surface. Subs are heat-treated

to 120,000 psi minimum yield strength.

Circulating Subs

Grant Prideco circulating subs (below) are made to order to meet

customer-specific requirements. Circulating subs can be provided

with inline or side ports and can be pressure tested if required.

Top Drive Saver Subs

Grant Prideco top drive saver subs undergo a more rigorous

application than other subs. They are subjected to the maximum

tension and torsion loads present in a drill string. In addition, top

drive saver subs are subjected to more make-and-breaks than any

other connection in the drill string.

Compared to other drill stem accessories, Grant Prideco requires a

more robust material for top drive saver sub applications. The subs

are manufactured from steel that meets ASTM specifications A370,

E23 and E30, and is pre-formed and drilled before heat-treating.

Subs are then batch heat-treated to obtain a minimum yield

strength of 120,000 psi, minimum tensile strength of 140,000 psi,

minimum Charpy impact strength of 40 ft-lbs at 70ºF and a

hardness of 293-341 BHN. The required mechanical properties

are at mid-wall of the pin. A thru-wall Brinell hardness is taken

at 1/4 inch below OD, mid wall and 1/4 inch from the ID. All

heat-treated blanks are sandblasted and wet-magnetic-particle

inspected prior to final machining and threading.

Rotary Kellys

Grant Prideco offers square and

hexagonal kellys, available up to

46 feet long. The kellys are made

from 4145-modified alloy bars that

are quenched and tempered full

length. A hardness range of 285 to

341 BHN and a minimum impact

value of 40 ft-lbs are maintained

one inch below the surface at

room temperature. All ends

and center drive sections are

machined. Grant Prideco kellys are

precision-trepanned to provide

true bores. They are drifted to API

specifications and all connections

are machined. Grant Prideco kellys

are stamped with the API

monogram, when applicable.

Top Drive Pump-In Sub

Top Drive Pump-In Subs

Specifically designed for use with top

drives, Grant Prideco’s pump-in sub

provides additional space (up to 3-1/2 feet)

between the bottom of the top drive

stabbing bell and the pump-in assembly.

The added space allows for easier

installation of your pump-in line assembly

and for safer operations when moving of

the drill string is required, such as landing

a casing liner. For an integral lift sub, the

top drive pump-in sub incorporates either

a 1502 or 2202 Weco thread as its upper

connection for the most common pump-in

connections.

Features and Options

Cold Rolling

A drill collar undergoes repeated severe tensile and compressive

stresses during the drilling operation. As compared with regular

drill pipe and heavyweight drill pipe, a drill collar is much stiffer,

focusing cyclic stresses on the thread roots and potentially resulting

in connection failure. To help alleviate this problem, Grant Prideco

cold-rolls the thread roots and the elevator recess upper radii on

every drill collar. Cold rolling imparts an initial state of compressive

stress that minimizes crack initiation, thereby increasing fatigue

resistance.

Phosphate Coating

All drill collar connections are given a hot phosphate coating to

provide resistance to galling and corrosion.

Proprietary Rotary-Shouldered Connections

In addition to the API and public domain connections listed in

the previous table, Grant Prideco can provide drill collars with

proprietary SST® and SRT® stress relief thread forms or double-

shouldered connections (see Rotary-Shouldered Connections

section) to increase performance. In addition to providing increased

connection fatigue life, SRT boxes reduce the length required for

recut by more than one inch compared to API stress relief features.

Stress Relief Feature

API pin stress relief groove and

boreback box provide increased

fatigue resistance and inhibit fatigue

failures. These features allow for

flexibility between the connection

and drill collar body reducing the

high-stress concentration that

normally occurs at the end of the

connection’s engaged threads. Both

stress relief features are machined in

compliance with the latest edition of

API Specification 7-1. NC23, NC26

(2-3/8 IF) and NC32 (2-7/8 IF)

connections are too small to accom-

modate stress relief features.

Care and Maintenance

Initial Make-up

A generous and thorough application of high-quality thread dope

(minimum 40-60% by weight metallic zinc) will help minimize

galling.

New connections should be “walked in” with chain tongs. Always

use the recommended make-up torque for the connection type.

Verify that torque measuring equipment is properly calibrated.

After initial makeup, break out the connection, then clean and

inspect the threads, faces and shoulders. Repair any minor damage,

re-lubricate and re-make the connection.

Repeat breakout and makeup a third time before going into the

hole. Monitor break-out torque; it should be the same or less than

the make-up torque. High break-out torque is an indication of

damage, and the connection should be inspected.

Maintenance

Use thread protectors on both connection ends when handling drill

collars. Rotate connection breaks 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.

Bending Strength Ratios

Sizes less than six inches should have a Bending Strength Ratio

(BSR) of 2.25:1 to 2.75:1. Conditions that require high RPM and

small collars compared to the hole size, use 2.25:1 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.

Although the current industry BSR calculation for single-shoulder

rotary-shouldered connection types may still be applicable for

double-shoulder connections (HT™, XT®, GPDS™), the appropriate

target ranges are yet to be defined due to limited industry

experience and testing of available types/sizes. Testing performed

to date indicates that current target BSR of 2.5 does not apply to

tested double-shouldered connections.

Just as target BSR for single shoulder rotary-shouldered connec-

tions has taken many years of industry experience to define, the

same may be true for these double-shoulder offerings. Additionally,

target BSRs for double-shouldered connections may likely vary

between connection types (i.e. GPDS vs. XT). Current industry

target BSR ranges should not be used as an indicator of double-

shoulder acceptance/rejection.
