1950

The roots of today's Hughes Christensen

Company go back to the turn of the 20th century

and embody the legacies of two pioneers of the

petroleum industry. The names of Howard

Hughes, Sr. and Carl Baker are synonymous with

rotary drilling. Their patents for inventions in the

early 1900s launched businesses that led to the

creation of Baker Hughes Incorporated, when

Baker International and Hughes Tool merged in

1987. In the 1940s, Frank and George

Christensen were the driving force behind

diamond bit development and the creation of

Christensen Diamond Products. In 1990, Baker

Hughes bought Christensen and over the next

two years, the industry's first rolling cone bit

company and first diamond bit company evolved

into Hughes Christensen, a Baker Hughes

Company. Hughes Christensen's research and

development programs have been the key to the

systematic advancement of drill bit technology.

Drill bit performance has played a major role in

helping the petroleum industry find and produce

energy worldwide.

1946 - Successfully introduced diamond coring bits to the petroleum industry in the Rangely field of Colorado.

1909 - Invented the first rotary rock bit equipped with two conical cutters that rolled on the bottom. This bit revolutionized rotary drilling by making it possible to drill rock formations faster.

1910 - Established the first research laboratory to study rock bit performance.

1921 - Introduced the Simplex bit. This design had a replaceable wash pipe down the center of the bit that allowed for the use of more powerful mud pumps which resulted in dramatic improvement in rates of penetration.

1925 - Developed self-cleaning cones that more than doubled the footage and penetration rate of rock bits.

1929 - The application of hardfacing on the cutting structure of cones to further increase rate of penetration and footage drilled per bit was introduced.

1932 Introduced the anti-friction ball and roller bearing. This design called for the retention of the cones on a cantilevered bearing shaft while balls are inserted through a hole in the bit leg. This constituted one of the biggest improvements in bit bearings at that time. 1933 Introduced the Tricone (3 cone) design with interfitting teeth that has since gained universal acceptance and still dominates the industry to this day.

1933 - Introduced bit records to analyze drilling performance and plan future drilling programs.

1951 - Introduced the R-1 Hugheset bit. This was the first of the tungsten carbide tooth bits designed to increase penetration rate and bit life while drilling chert and other hard, abrasive formations.

1952 - Introduced the first non-coring surface set diamond bit for oilfield application. This design was made possible by using a proprietary erosion resistant matrix and a powder metallurgy process for mounting diamonds in the bit crowns.

1953 - Pioneered the use of integral jet rock bits for better utilization of hydraulic horsepower in the drilling operation.

1959 - The first practical and effective self-lubricated sealed bearing bit with a carbide cutting structure was introduced.

A T r a d i t i o n o f I n n o v a t i o n

1960 - Introduced impregnated diamond bits. These bits used sintered cutting segments composed of sharp, grit size diamonds mixed with tungsten carbide.

1964 - Two new lines of bits were introduced. The X-Line included both steel tooth and carbide rock bits combining the latest cutting structure designs with fully sealed bearings.

1966 - Introduced Hughes-X hardfacing and HEEL PACS to keep the hole full gauge. Also introduced X55R the first of the shaped compact design bits to drill more plastic formations than was possible with other tungsten carbide bits.

1970 - Introduced the first tricone steel tooth bit using an O-ring sealed journal bearing with special alloy inlays.

1976 - Introduced synthetic polycrystalline diamond compact (PDC) bits, increasing the capability of diamond products to drill softer formations.

1976 - Introduced vacuum/pressure greasing method for filling lubricant reservoirs of sealed bearing bits.

1981 - Developed the scoop shaped chisel tungsten carbide compact. This design added to compact strength, and exerted a mechanical lifting action on cuttings.

1981 - Introduced an entirely new synthetic product called BallaSet, the first thermally stable diamond. This technological breakthrough was achieved by removing or replacing the catalyst metal with a less thermally expansive material. This created a diamond-to-diamond bonding structure withstanding generated frictional heat (up to 1200 degrees C) when drilling harder and more abrasive formations.

1985 - Created a full-scale Drilling Simulator capable of testing bits up to 12-1/4" in diameter. The Simulator enabled our researchers to accurately assess and compare the performance of new rollercone bit designs in simulated downhole environments..

1987 - Introduced the world's first metal sealed rock bit bearing designed specifically for the rigors of high speed and high temperature drilling.

1987 - Introduced “King Cutter” PDC bits that utilized large polycrystalline diamond cutters ranging from ½" to 2" in diameter. This extended the range of diamond drilling into the large, top-hole sections drilled offshore

1987 - Introduced “Rocky” software. Rocky, a versatile log interpretation software tool, was designed to predict rock strength and drillability for improved product applications.

1989 - Tested the first anti-whirl PDC bits designed to resist whirl and associated cutter damage. This technology extended the application range of PDC bits.

1995 - Introduced polished cutters to PDC bits which dramatically improved drilling efficiency by lowering frictional forces.

1995 - The ChipMaster PDC bit was introduced, incorporating patented rear impact hydraulics that provide unmatched hydraulic efficiency in poor hydraulic (low HSI) applications.

2000 - Introduced the eccentric Drill-Out Ream While Drilling tool. This RWD tool was the first device allowing operators to drill out cement, then continue to drill and ream the formation interval in one run.

2002 - Designed the unique HedgeHog cutting structure. This post-on-blade configuration adds up to 50% more diamond volume for extended life.

2003 - Introduced EZSteer, a new depth-of-cut-control technology, which tempers PDC aggressiveness and improves tool face control on directional assemblies without sacrificing penetration rate.

Product Evaluation LabHughes Christensen's emphasis on continuous improvement is reflected in our Product Evaluation Lab. We diagnose product wear and failure modes, not only to determine the causes for the various conditions, but also to identify opportunities for performance enhancing features. In the lab, we literally “autopsy” bits that have been returned from fields worldwide. Our engineers perform in-depth failure analysis of the cutting structures, bearings, seals and other areas on all types of bits. This post-mortem analysis gives us the information to help our customers optimize drilling practices and conditions, to provide the most economical bit performance, and to eliminate recurrence of performance problems in future wells. By analyzing experimental products, we are able to quickly determine the value of new design features and if modifications are warranted to further improve future performance.

Baker Hughes Experimental Test AreaHughes Christensen's parent company, Baker Hughes, has created a field research facility located south of Tulsa, Oklahoma. This new facility is designed to expedite the development and commercialization of drilling systems for the oil and gas industry. The Baker Hughes Experimental Test Area (BETA) provides a major bridge between small-scale simulator testing and full-scale field applications of downhole tools. Testing at BETA enables us to evaluate systems without the costs and constraints associated with a well being drilled for production.

This one-of-a-kind facility is equipped with the latest, most sophisticated real-time data acquisition system in the world. This system enables our engineers to monitor virtually every variable and also allows digital analysis of frequency-based data as well as time-based data.

FEAAs part of Hughes Christensen emphasis on product reliability, our engineers use the state-of-the-art ABAQUS FEA package to solve 3D, highly non-linear problems with contact. The FEA package allows us to model stress and strain in metals, rubber and rock-like materials. Because of FEA, bit designs can be optimized for durability, cutting structure failures can be predicted without lab or field tests, and the customer receives a better product faster.

Research areas where FEA excels include:

• Providing an understanding of contact stresses, which are subsequently reduced through the development of new bearing geometries

• Comparing stresses in 3D carbide tooth shapes in order to develop stronger teeth

• Comparing material models, such as carbide grade differences or the effects of carbonization

• Modeling residual stresses in PDC cutters, which allow us to develop “Stress Engineered Cutter” technology

Materials ResearchHughes Christensen conducts extensive materials research to improve the durability and overall performance of roller cone and fixed-cutter drill bits. From the industry's most durable hardfacing material for roller cone bits to improved tungsten carbide matrix and diamond components for fixed cutter bits, our materials research activities have resulted in record-setting performance worldwide. Due to the highly complex system of moving parts within a roller cone bit, our materials researchers follow a synergistic approach where each component is evaluated in the context of its relationship to other components in the system. This approach enhances the probability that performance-limiting deficiencies are correctly identified and addressed. This approach has resulted in the successful introduction of improved greases, bearings and seals. The same approach has been utilized to develop the industry's toughest hardfacing material as well as improved diamond and carbide components that have helped make our steel tooth and TCI product lines become consistent record setters.

Hughes Christensen uses a variety of analytical tools to characterize its materials and parts. Optical and electron microscopy are used for phase and fracture surface studies and profilometry is used to document the effects of wear. Material properties such as strength and toughness are tested continuously on our boring mill and rock planar machines.

Solid Modeling Design CapabilityHughes Christensen continues to lead the industry in cutting-edge technology by designing both Tricone and Diamond bits utilizing state-of-the-art solid modeling CAD packages. The modeling tools are customized to accelerate the design process and ensure high quality. Design intent can easily be verified utilizing these systems for visual inspection. Also, solid modeling allows for seamless transfer of product models to high-end analysis tools to further our design capabilities. Once the model is finalized, an efficient semi-automated process is used to create the drawing packages for production.

Numerically controlled (NC) programs are then generated directly from the solid model using the latest in CAM technologies. These programs are checked through computer simulations to ensure error-free information before reaching the shop floor. The simulations check for tool interference with fixtures and ensure that the intended geometry will be correctly created on the shop floor to reduce waste and improve overall efficiency.

Drilling Technology LaboratoryMany of Hughes Christensen's advances in improving penetration rate and fine-tuning performance features of Tricone and diamond drill bits are implemented at our High Pressure Drilling Test Facility. With our full-scale drilling simulator, where we bring the field to the laboratory, the research and development cycle that once took months in the field has been reduced to days. The Drilling Simulator, which is capable of testing bits up to 12 1/4” in diameter, reproduces the downhole environment to enable our researchers to accurately assess and compare the performance of new designs as well as standard products. Drilling parameters including weight on bit, rotary speed, rate of penetration, and bit hydraulics, are computer controlled throughout the individual tests. After each test, the bit, borehole, and bottom hole pattern can be examined immediately to ascertain characteristics of the test bit providing information which would be impractical to obtain in the field.

Complementing the high-pressure drilling simulator is the full-scale atmospheric pressure test facility for conducting wear studies, visualization tests, and dynamic analysis of rolling cone and fixed-cutter bit designs.

Hydraulics Planning Software

Hughes Christensen's Windows-based Hydraulics software program allows us to develop an inclusive hydraulics plan for optimizing each bit run for an entire drilling program. An important feature of our software is the ability to alter some of the well data on any single bit run such as pump pressure and downhole tools. Additionally, the software can be used to design the mud flow split for some of our hole enlarging tools like DORWD. The resulting hydraulics program incorporates this modified information into a detailed comprehensive report for each bit run.

The capacity to alter operating parameters is what sets our software apart. Our bit specific application software takes into account the significant changes in operating conditions that occur with increased depth including changes in mud weight and viscosities as well as increased drill pipe friction. What may apply at the start of a run could yield conditions that starve a bit before its planned finish, reducing performance and shortening bit life. The result is a custom tailored hydraulics program to optimize each bit run to cut your drilling costs.

OASIS Engineering &

Consulting Service®OASIS is Hughes Christensen's bit

optimization service package that combines in-house engineering with custom site consultation to reduce drilling costs. OASIS University provides the training and tools for Hughes Christensen's team of application engineers to excel in providing high-end bit optimization solutions. Drawing upon an extensive training regimen, OASIS personnel have the benefit of an extensive knowledge database to deliver best practices in any application. The OASIS approach is a three-step process of planning, drilling, and post-well analysis. Knowledge management and lessons learned in each phase of the process are key to continual improvements in bit optimization. Every OASIS project starts with a detailed study of offset wells to benchmark current performance and determine areas of possible improvement. Bit selection, formation drillability, drilling parameters, vibration control, and maximizing penetration rates are all analyzed as part of the planning process. As the well is being drilled, the OASIS engineer follows daily progress, attends team meetings, updates the well prognosis, and helps devise strategies to overcome any unforeseen problems.

After completion of the well, a complete analysis is performed to document achievements as well as problems. Finally, a report is produced that compares actual results to predicted performance to carry the lessons learned forward to the planning of the next well.

Rock Mechanics Software

Rocky is a state-of-the-art rock mechanics software program. This unique tool provides full-featured visualization and is capable of providing fast and effective single and multiple well log presentation, tops picking, and log printing functionality using digital well log data. As an analytical tool, Rocky calculates confined and unconfined compressive strength from offset wireline logs. Rocky can input a wide variety of information in its program including data from sonic, gamma ray, and caliper logs. The program also indicates formation balling tendencies, abrasiveness, and rattiness. By combining offset data with log information, Rocky gives our engineers a precise look at the downhole environment. With a better understanding of the application, we can more accurately determine which bit type will deliver the most value.

Bit Records/Bit Programs

When you do business with Hughes Christensen, you automatically gain access to the world’s most comprehensive database of drilling information. For more than five decades, we have carefully recorded detailed information from thousands of wells worldwide. Whether you are planning a wildcat in an unproven area or wanting to improve performance in a mature field, our stockpile of run information can help you make the right decision. With our web-based Bit Record Database Query System, Hughes Christensen field personnel can quickly access a full range of offset well data.

Another benefit of our extensive database is engineered bit programs specifically designed to meet the objectives of your proposed well. These expertly engineered programs help your HCC representative identify potential problem areas prior to spudding. Bit selection, application, and operating parameters are recommended on the basis of formation strength analysis, abrasiveness of the formation, and bit hydraulics in addition to directional concerns and rig capabilities. With our comprehensive lines of Tricone and fixed-cutter bits, we can offer you an unbiased approach in designing programs that properly match the bit with the formation and operating parameters.

Well Recapping

Like dull grading, the practice of well recapping is a very useful barometer for selecting the proper bit for a specific application. With our inclusive well recaps, we look at the entire well to document the performance of the bit as compared to the well program. In a well recap, the actual drilling time, day versus depth, drilling costs, hydraulics, rate of penetration, and other factors influencing drilling efficiencies are compared against the program estimates. Recapping well performance helps document achievements as well as failures and helps when planning your next well.

Customer Service

Dull Bit Grading

Another integral part of Hughes Christensen’s valuable customer service is the evaluation and grading of dull bits once they leave the wellbore. This service is extremely useful for selecting the most cost-effective bit for a subsequent well in a specific area. Examining a dull bit provides you and Hughes Christensen’s representatives an accurate look at what occurred during the drilling process and what adjustments should be made in the bit selection process for future wells. An analysis of dull bits also provides insights into how operating parameters can be adjusted for improving performance and lowering costs in upcoming wells. Dull grading also gives our research engineers valuable insight into the downhole environment. This knowledge is incorporated into our new designs and also assists in the modification of existing designs.

Customer Training

Since its inception in 1968, the Hughes Christensen Customer Drilling Seminar has become the industry standard for the timely sharing of oilfield technology. Held four times per year at The Woodlands, TX headquarters, the three-day seminar covers a specialized yet broad range of information including tours of all manufacturing facilities and the drilling simulator. Depending on needs, variations of the seminar also can be presented in customer locations worldwide. Complementing the Drilling Seminar is an expanded technical training program with modules on such subjects as rock mechanics, drill string vibration, hydraulics, dull grading, bit selection, and application and bit design. The modules, which can be taught at either Hughes Christensen or customer locations, are focused on a single objective: to help our customers incorporate more efficiency in their drilling operation.

Features

Equalizer Lubrication PackageA new modified grease formulation provides lower torque, less heat and reduced wear in the sealing area. Also included in the Equalizer package is an improved compensation system. The compensator is made with HSN elastomer material for improved heat and chemical resistance. Its spring energized compensator cap reduces vibration and fretting.

Excluder PackageThe Excluder package is comprised of new technology targeted specifically at preventing the detrimental effects of mud packing. The cornerstone of the package is an elastomer backup ring. Strategically positioned to occupy a space where particles once invaded, the ring acts as a static seal between the mud and seal package. Also working against the effects of mud packing is the Mud Wiper and Cone Backface Groove which work in tandem to wipe away packed-in mud.

SEM Bearing PackageUltraMax utilizes a patented single energizer metal sealing system (SEM) which is far simpler, yet more robust than earlier technology. Fewer sealing components and tighter tolerances insure fewer avenues for leakage and greater reliability in the tough applications. Additional bearing refinements like a silver plated insert and new bearing geometry add up to a tougher bearing ready to provide long hours under the most strenuous operating conditions.

GX broad range of soft to medium applications

GX is a new line of premium elastomer

sealed Tricone bits. Our engineers have

successfully combined a fast bit design

with tougher carbide grades and more

durable compact shapes. Add to this the

availability of four proprietary hydraulic

configurations and you have a line with

unmatched flexibility and the ability to

provide the right solution for virtually any

Tricone application. GX bits utilize a new

third-generation bearing, more robust leg

protection and longer engineered

compact shapes. These new technologies

enable GX bits to drill a broad range of

formations for longer hours at faster

penetration rates.

Features

Standard GX

Optimized Carbide Grades Research into the chemical and physical properties of the carbide alloy have produced materials with a maximum level of wear resistance for each level of toughness.

Engineered Compact ShapesNew durable shapes are the result of rigorous research into the shape and composition of individual compacts. Hughes Christensen engineers broke down the compact design into individual attributes including grade, projection, cone angle, and various radii, methodically testing these elements to evaluate different shapes for durability and cutting aggressiveness. HCC designers can fine-tune GX Tricone compacts to match specific formations and applications.

Multi-Position Heel Application specific heel designs provide improved durability and faster rates of penetration. GX bits are designed with an application specific Multi-Position Heel that evenly distributes the cutting load between heel and adjacent heel compacts to provide improved durability and faster rates of penetration.

G3 BearingAll GX bits are equipped with third-generation elastomer-sealed journal bearings that are designed for maximum load capacity and long life in both rotary and motor applications. New non-cylindrical journal geometry and high-precision machining equipment eliminate points of high stress on contact surfaces and provide tighter design tolerances.

Excluder PackageGX bits utilize an excluder package with a series of features aimed at preventing the detrimental effects of mudpacking. Mud Wiper works in tandem with a backface groove to wipe away packed-in mud. Beveled Shroud protects seal area from contamination. Beveled Shirttail Contour provides an avenue through which cuttings can channel away from the seal.

GX HydraulicsHughes Christensen GX bits offer both biased and unbiased hydraulic configurations that are fine-tuned for specific applications. After analyzing the formations and operating parameters the GX bits will encounter, our engineers can specify the optimal hydraulic system configuration to ensure superior cone cleaning, minimal bit and bottom-balling, and excellent rates of penetration.

Conventional HydraulicsStandard nozzle configuration directs fluid between the cones toward the corner of the borehole wall. Hydraulic energy is focused at the formation.

Clean Sweep 2 & 3 HydraulicsNozzles are positioned so that the fluid stream cleans the heel and adjacent heel teeth. The majority of the hydraulic energy is focused on the cutting structure.

XStream HydraulicsNozzles are positioned so that multiple rows of cones are cleaned and high turbulent energy is created at the bottom of the hole.

Enhanced Leg ProtectionEndura II hardfacing is liberally applied to the shirttail for enhanced protection of the bearing seal area. Shirttail compacts are strategically positioned within the shirttail to reduce leg wear in abrasive formations and directional applications.

Cone Savers Cone savers add exceptional cone steel protection without sacrificing penetration rate. Many GX bits incorporate strategically positioned cone savers to protect the cone steel against abrasion by cuttings or contact with the formation. Cone savers preserve the integrity of the cutting structures without sacrificing penetration rate.

GENESIS XT maximum performance and stability

Until now, drilling hard and abrasive

interbedded intervals has been impractical for

PDC bits. With the introduction of Genesis XT,

Hughes Christensen offers a line of PDC bits

that are capable of drilling farther and faster

through harder, more abrasive formations

than ever before.

The XT is the result of a two-phase research

effort. Our engineers first developed a

tougher, more abrasion-resistant cutter

capable of maintaining a sharp, efficient

cutting edge in hard carbonates. Second, they

devised bit designs that mitigate vibration in

ratty formation to reduce the impact loads on

cutters. The result is a line of PDC bits that

can drill challenging intervals consistently at

the highest possible penetration rate.

Computational Fluid Dynamics (CFD)Hydraulic efficiency is imperative to maximizing cuttings removal and reducing the bit’s tendency to ball. The hydraulic configuration of every Genesis XT design is optimized through a proprietary CFD process to ensure the best balance between fluid flow, cutter cooling, and erosion.

Design Application Review ProcessEach Genesis project receives the custom attention of an integrated, multi-functional team comprised of a design engineer, a research engineer, an application engineer, and an account representative. The Design Application Review Process provides an in-depth analysis from various perspectives, improves communication with customers, reduces costly, time-consuming iterations and maximizes the quality of the solution.

Features

Z Series CuttersZenith cutters feature a surface layer with superior wear resistance and body layers with outstanding toughness. Improvements in cutting mechanics and durability allow Z cutters to maintain a sharp, efficient cutting edge when drilling through a wide variety of formations under extreme downhole conditions. Zenith cutters can withstand the punishment of challenging downhole environments without sustaining ROP-killing cutter damage.

SmoothCut TechnologyIn hard, interbedded formations, the key to preventing efficiency-killing cutter breakage is to control cutter loading. Through SmoothCut depth-of-cut control technology, cutter-damaging peak loads are minimized by balancing the workload over more cutters. SmoothCut technology limits bit aggressiveness without limiting ROP. XT bits run smoothly with minimal vibration, and take full advantage of the superior wear resistance of Zenith cutters.

Improved StabilityBit stability plays a key role in both cutter durability and drilling efficiency. Genesis technology reduces vibration severity, improves the bit's resistance to whirl, and increases protection of the cutter from impact damage. The result is smoother, more efficient drilling.

Smoother drilling

Low-Imbalance/Kerfing - Cutter redundancy creates large grooves in the hole bottom to reduce lateral bit vibration.High-Imbalance - Net imbalance force pushes the bit against the hole wall, creating a stable rotating condition.

Reduce vibration severity

Chordal Drop - Reducing the space between the bit body and the wall of the hole minimizes vibration

BRUTE Cutters - Patented BRUTE cutters can be used to reduce wear of the bearing surface when drilling abrasive formations.

target.

Because toolface orientation and slide

drilling are unnecessary with rotary

steerable systems, HCR bits can be

optimized for high penetration rates and

longer life. Each Genesis HCR bit is backed

by our commitment to deliver exceptional

stability, unequaled hole quality, and

industry-leading penetration rates.

GENESIS HCM motor steerable

Genesis HCM bits are designed specifically

for steerable motor applications. These

advanced bits offer the best of both worlds:

the longevity and penetration rate of

traditional PDC bits, along with the control

and precision of roller cone bits. Features

like Genesis cutters, Computational Fluid

Dynamics and enhanced stabilization

complement the patented EZSteer depth-of-

cut control technology which limits reactive

torque and provides excellent tool face

control. Genesis HCM bits are designed for

accurate placement of quality wellbores at

the highest possible rates of penetration.

BRUTE CuttersPatented BRUTE cutters can be used to reduce wear of the bearing surface when drilling abrasive formations.

Z Series Cutters (optional)Zenith cutters feature a surface layer with superior wear resistance and body layers with outstanding toughness. Improvements in cutting mechanics and durability allow Z cutters to maintain a sharp, efficient cutting edge when drilling through a wide variety of formations under extreme downhole conditions. Zenith cutters can withstand the punishment of challenging downhole environments without sustaining ROP-killing cutter damage.

Genesis Application-Specific CuttersOur designers can choose from a family of cutters with a range of properties for the ideal combination of efficiency and durability.

Gauge Design FlexibilityThe gauge configuration for each Genesis HCM PDC bit is chosen on an application–specific basis. Directional precision and hole quality vary by application, and each Genesis bit is optimized to meet those specific requirements.

1. Shorter gauges are appropriate for applications demanding high doglegs and precise directional work.

2. Medium gauges provide improved hole quality in less demanding directional applications.

3. Long gauges are ideal when the primary focus is hole quality.

A V A I L A B I L I T Y

Computational Fluid Dynamics (CFD)Every design is hydraulically optimized using CFD to reduce balling tendencies, improve cutter cooling, and minimize fluid erosion.

EZSteer TechonologyPatented EZSteer depth-of-cut control technology uses engineered bearing surfaces to improve tool face control without sacrificing penetration rate. Genesis HCM bits drill as efficiently as standard PDC designs until the bearing surface engages the bottom hole. Beyond that threshold, they behave more like roller cone bits to dramatically decrease reactive torque and improve steerability.

Directional control is enhanced by lowering the bits torque response to additional weight with patented “depth-of-cut-control” technology.

hard / interbedded formations

HedgeHog is a revolutionary new impregnated

bit that raises the bar when drilling

interbedded formations. It features an

aggressive, balling-resistant cutting

structure with optimized hydraulics and

advanced matrix material. Its interrupted

cutting structure and optimized blade count

allow the bit to take a bigger bite out of shale

formations. By successfully drilling hard

sandstone interbedded with soft shale, the

HedgeHog line has dramatically expanded the

range of impregnated drill bits.

Innovative Cutting Structure

• Interrupted cutting structure allows shale to flow between the posts which enables the

cutting element to drill more efficiently.

• Post-over-blade design adds 25% more diamond volume than standard impregnated bit.

• Overlapped posts are staggered to increase drilling efficiency and eliminate any uncut bottom.

• Maximized blade count delivers optimal sand and shale drilling.

Matrix Flexibility

For maximum bit performance, our designers select the

matrix most suitable for the application. Each matrix

formulation matches the formation to be drilled so the

carbide matrix wears slightly faster than the diamond.

This ensures that fresh, sharp diamonds are exposed at

the optimal rate.

RWD2 ream while drilling / drillout

Regardless of your application (rotary,

rotary steerable, motor steerable),

Hughes Christensen has a tool that

enables you to drill out cement and float

equipment and then drill and ream the

remaining interval in one continuous

operation. Our RWD2 (rotary), RWD2S

(steerable) and RWD2ST (slimhole) fixed

blade eccentric reamers are designed to

tackle hole opening applications in the

most demanding well bore geometries.

RWD reamers eliminate the risks and

performance limitations associated with

bi-center bits and conventional

underreamers.

The RWD2 family of products provide

- Improved “drill out” capability

- Unmatched steerability

- Superior hole quality

- Outstanding pilot bit and BHA flexibility

1. RWD2 Designed for straight hole, rotary applications, the RWD2

tool has, in many cases, reduced by half the costs associated with

conventional drilling and reaming techniques. The RWD tool allows you to

select the ideal combination of pilot bit and BHA assembly to optimize

drilling efficiency, translating to dramatically reduced cost per foot.

2. RWD2S In directional wells, RWD2S technology slashes the costs

of underreaming while eliminating the mechanical risks associated with

conventional reamers. Its two-piece, box down, pin up configuration

makes it ideal for either motor steerable or rotary steerable systems.

3. RWD2ST The RWD2ST is a customized one-piece matrix design

built specifically for slimhole applications. Its pilot bit / reamer design

provides maximum hole clearance to greatly reduce the risk of

mechanical failure in tight well bores.

1 2 3

Genesis Cutters

The RWD2 family utilizes the same tough, abrasion-

resistant cutter technology as our industry-leading

Genesis PDC bits.

BHA Flexibility

The two-piece RWD2 configuration allows the tool to be

placed either below or above a motor, or virtually

anywhere in rotary or rotary steerable BHAs.

Pilot Bit Flexibility

The two-piece RWD2 design allows either Tricone or PDC

pilot bits to be used, depending on the requirements of

each application.

Depth Adjusted Cutters

Using a patented approach, the exposure of individual

cutters is carefully adjusted to balance the load

distribution. This reduces vibration and improves cutter

durability.

Optimized Hydraulics

Computational Fluid Dynamics (CFD) is used to optimize

nozzle positioning on every RWD2 design to maximize

cuttings removal and cooling of the cutting structure.

Active Stabilization Pad (ASP)

This patented, precisely engineered pad offsets the cutting

forces from the reamer to improve bit stability and provide

excellent directional response and hole quality.

Hole Opening Blade

Patented blade design provides smoother drilling during

the transition from pass through to drill size.

Drill Out Protection

Durable, unaggressive tungsten carbide inserts are

placed on RWD2 blades to protect the casing while

SPECIALTY DRILLBITS

Natural Diamond Bits

Hughes Christensen offers natural

diamond bits in a variety of styles for

both motor and rotary drilling in hard or

abrasive formations. Various sizes,

grades, and concentrations of natural

diamonds are used in these bits to

match the requirements of your specific

application. As with other Hughes

Christensen diamond bits, crown

profiles of our natural diamond bits are

designed for optimum performance for a

specific formation and application. SideTrack

Our sidetracking bits feature shallow

cone profiles that produce minimal

resistance to directional changes. The

short shoulder radius enhances the

lateral cut when side forces are applied

for successful kickoffs. Hughes

Christensen sidetracking bits are

available with PDC, Ballaset and natural

diamond cutters to meet all your

applications. All sidetracking designs

feature tungsten carbide matrix body

construction for erosion resistance

and all have natural diamond

protection at the gauge.

Speed Mills

Diamond speed mills utilize a flat profile

with short shoulder radius. This profile

provides the greatest surface area in

direct contact with the casing. The short

shoulder radius is designed to combine

durability with an aggressive edge to

begin the casing window. Our speed mills

utilize small 10-12 SPC diamonds evenly

distributed in a grid pattern. The smaller,

less exposed diamonds have high impact

resistance to prevent breakage while

drilling steel casing. The gauge, designed

with abrasion resistant natural diamonds,

are flush set to provide the greatest

protection when drilling through steel

casing.

Secondary Bypass Port

A rupture disk in the bit OD allows for higher

flow rates while cementing.

PDC Cutting Structure

A full PDC cutting structure allows efficient reaming

and drilling in a broad range of formations.

Engineered Nozzle

Placement

Drillable carbide nozzles provide higher hydraulic

horsepower. Their placement is optimized by

Computational Fluid Dynamic analysis which

maximizes cuttings removal and cutter cooling.

Drillable Alloy Body

Special alloy construction allows either a mill tooth bit or

a specialized PDC bit to drill out the EZ Case bit along

with the shoe track.

EZCaseTMHughes Christensen’s new EZCase

casing bit system comprises a special

alloy shoe fitted with a full PDC cutting

structure. This unique tool allows

operators to combine drilling and casing

in one run and reduce the risks

associated with problematic wells.

EZCase provides a means to complete

wells challenged by well bore stability

problems caused by depleted reservoirs,

lost circulation, and rubble zones. Its

drillable shoe design allows additional

casing strings to be run in the hole to

significantly reduce “flat time” while

allowing shoe-to-shoe drilling.

Ballaset

BallaSet bits use thermally stable,

self-sharpening TSD cutters for fast

penetration and long life in medium to

hard and abrasive formations. BallaSet

bits are custom designed for specific

applications. Crown profiles are

designed to optimize penetration rates

and bit life in a specific formation when

running rotary and motor

applications. Bits with triangular

BallaSet diamonds typically are used to

drill medium hard formations. The disc-

shaped BallaSet diamonds offer better

ROP and longer life in hard and

abrasive or fractured formations.

47

Spiral Gauge (G6)Helps reduce the space between the bit body and the wall of the hole. The Spiral Gauge option is one of many Chordal Drop Management tools designed to reduce vibration severity.

Extended Sleeve

Box-Up Connection

(G9)For greater bit stability when drilling with high rotational speeds, an optional gauge sleeve may be added.

(Y)Some directional drilling applications utilizing turbines require the smallest possible distance between the bit face and the lower bearing stabilizer. This can be achieved by using a pin-down connection on the turbine.

In-Gauge PDC Trimmers (G5)Additional PDC cutters are flush mounted on the leading edge of the gauge pads. They provide extra durability on the bit gauge pads for applications that prematurely wear a conventional TCI/ND gauge.

DIAMOND PRODUCTS

Longer Gauge Than Standard (G8)The G8 option is any gauge length that is longer than the standard gauge length for a given bit size. In some high-rotation speed applications such as using turbines, maximum bit stabilization and durability is required. Therefore, gauge length is increased to meet specific application requirements.

48

Duraset Gauge (G4)This patented gauge design incorporating tungsten carbide bricks and natural cube diamonds provides the highest abrasion resistance available

Brute Cutters In Gauge (G10)Brutes are vertically placed PDC cutters which reduce bit vibration

Step Gauge (G3)The upper portion of the gauge pad has a reduced OD for better steerability.

Flatset PDC in Gauge (G11)(steelbody bits) PDC cutters placed flush in gauge area provide additional protection in abrasive applications.

Wear Knot (K)Matrix pads located behind the PDCs restrict the depth of cut. Used almost exclusively in horizontal or high angle drilling, Wear Knots help minimize large torque variations that could cause the toolface angle to swing erratically.

ChipMaster Hydraulics (M1)Chipmaster bits utilize a unique blade geometry and rear impact hydraulics to encourage cuttings movement quickly into the junk slot and up the annulus.

Slick Bit Coating (SB)An optional polymer coating applied to bits to reduce “bit balling” in shale formations.

Lateral Movement Mitigator (LMM)A Lateral Movement Mitigator is formed by building up the blade and upper shoulder. Adding an LMM reduces vibration severity and protects cutters from impact.

Orders for rental equipment ("Equipment"), services ("Services"), and the supply or sale of products or equipment ("Products") to be provided by BAKER HUGHES INCORPORATED, or its operating divisions, or its direct or indirect wholly-owned subsidiaries (in each case as applicable referred to herein as “BHI”) to its customers (each a "CUSTOMER”) are subject to acceptance by BHI, and any orders so accepted will be governed by the terms and conditions stated herein and any additional terms proposed or agreed to in writing by an authorized representative of BHI (these terms and conditions and any such additional terms collectively referred to herein as the "Agreement'). Any additions to or modifications of these terms and conditions, or any terms and conditions contained in CUSTOMER's order inconsistent herewith, shall not bind BHI unless accepted in writing by an authorized representative of BHI.

1.PAYMENT TERMSUnless alternate payment terms are specified or approved by the BHI Credit Department, all charges, including applicable packing and transportation costs, billed by BHI are payable within thirty (30) days of the date of invoice. At BHI's option, interest may be charged at the rate of ten percent (10%) per annum unless such rate contravenes local law in which case the interest charged will be the maximum allowed by law. Operating, production or well conditions which prevent satisfactory operation of Equipment, Services or Products do not relieve CUSTOMER of its payment responsibility.

2.CANCELLATIONProducts: Orders for Products which are subject to cancellation after acceptance by BHI will be subject to a restocking charge of at least twenty-five percent (25%), plus any actual packing and transportation costs. Products specially built or manufactured to CUSTOMER specifications, or orders for substantial quantities manufactured specially for CUSTOMER, may only be canceled subject to either (i) payment of a cancellation fee by CUSTOMER, or (ii) a return credit against future purchases, to be determined solely by BHI. Credit for unused Products will be issued for the quantity returned at the original purchase price, less restocking or cancellation charges, provided the returned Products are in reusable condition. No credit will be given for shipping charges incurred by CUSTOMER. In no event will credit be allowed for Products returned without prior written authorization by BHI.

Equipment/Services: In the event CUSTOMER cancels an order for Services or Equipment, CUSTOMER shall be liable for all costs incurred by BHI in the mobilization/demobilization related thereto, and any other reasonable costs incurred by BHI incident to such cancellation. In addition, a restocking charge of at least twenty-five percent (25%) of the original order may be applied at BHI's sole discretion.

3.THIRD-PARTY CHARGES, TAXESCUSTOMER shall pay all third-party charges, in compliance with BHI's current price list, and any sales, use, rental or other taxes that may be applicable to transactions hereunder. CUSTOMER shall pay all applicable customs, excise, import and other duties unless otherwise agreed to in writing by an authorized representative of BHI. CUSTOMER shall provide necessary import licenses and extensions thereof.

4.RISK OF LOSS AND TITLEFor Product sales within the United States of America, title and risk of loss shall pass to CUSTOMER as soon as the Products depart BHI's point of origin. For Product sales outside the United States of America, unless otherwise agreed to in writing between BHI and CUSTOMER, INCOTERM “CPT” shall apply with the following exception: TITLE AND RISK OF LOSS REMAIN WITH BHI UNTIL THE PRODUCTS REACH THE PORT OF ENTRY.

5.LIABILITIES, RELEASES AND INDEMNIFICATION:A. In this Agreement, "Claims" shall mean all claims, demands, causes of action, liabilities, damages, judgments, fines, penalties, awards, losses, costs, expenses (including, without limitation, attorneys' fees and costs of litigation) of any kind or character arising out of, or related to, the performance of or subject matter of this Agreement (including, without limitation, real or personal property loss, damage or destruction, personal or bodily injury, illness, sickness, disease or death, loss of services or wages, or loss of consortium or society).

B. BHI shall release, indemnify, defend and hold CUSTOMER, its parent, subsidiary and affiliated or related companies, and the officers, directors, employees, consultants and agents of all of the foregoing (referred to in this Agreement as "CUSTOMER INDEMNITEES") harmless from and against any and all Claims asserted by or in favor of any member of BHI INDEMNITEES (as defined in paragraph C. below) or BHI INDEMNITEES' subcontractors at any tier or their employees, agents, or invitees.

C. CUSTOMER shall release, indemnify, defend and hold BHI, its parent, subsidiary and affiliated or related companies, and the officers, directors, employees, consultants and agents of all of the foregoing (referred to in this Agreement as "BHI INDEMNITEES") harmless from and against any and all Claims asserted by or in favor of any member of CUSTOMER INDEMNITEES or CUSTOMER INDEMNITEES' contractors at any tier (except BHI INDEMNITEES or BHI INDEMNITEES' subcontractors) or their employees, agents or invitees.

D. Notwithstanding paragraph B. above, should any of BHI INDEMNITEES' or BHI INDEMNITEES' subcontractors' instruments, equipment or tools ("Tools") become lost or damaged in the well when performing or attempting to perform the Services hereunder, it is understood that CUSTOMER shall make every effort to recover the lost or damaged Tools.
