Dynamus AntiWalk Drill Bit Technology
Drill on time. Drill on target.

Dynamus™ AntiWalk drill bit technology reduces slide time toincrease rate of penetration (ROP), lower overall drilling time, andimprove wellbore placement. It also optimizes wellbore quality
and enables greater flexibility in BHA design.
Slides on conventional motor assemblies often account for up
to 50% of drilling time, yet only 10 -15% of the distance drilled.
AntiWalk technology tracks better to stay on target in all holesections and reduce the time spent sliding for corrections. This
enables you to spend your time optimizing ROP rather thancorrecting the wellbore trajectory. A unique stripe on the gauge
pad limits depth of side cutting against the borehole wall while
drilling ahead for reliable tracking, resulting in increased overall
ROP and reduced dogleg severity.

APPLICATIONS• Unconventional oil and gas wells• Motor directional assemblies• Wells prone to unplanned deviations• Vertical, curve, and lateral sections

BENEFITS• Optimizes section ROP for reduced drilling
time and costs• Tracks to stay on target in rotate mode
• Reduces number and severity of slides for

StayCool 2.0 Cutter Technology

APPLICATIONSStayCool™ 2.0 multidimensional cutter technology from Baker Hughers helps beatthe drilling day curve and reduce drilling costs by minimizing friction on the cutter
face, improving rates of penetration (ROP), and drilling more efficiently. Run on
the Baker Hughes Dynamus™ platform of extended-life PDC drill bits, StayCool 2.0
cutters use unique nonplanar diamond table geometry and polished cutter basetechnology to enhance performance in key applications.

BENEFITS

Beat the drilling day curve with cooler, sharper, more efficientcutter technology

In more challenging environments, like interbedded sandstones and carbonates,
bit performance is directly related to cutters and their ability to withstand heat.
StayCool 2.0 technology reduces heat generation at the cutter/rock interface. This
lengthens the life of the cutter, which leads to extended runs, fewer bit trips, andreduced overall time to reach total depth (TD).

• Conventional or unconventional
oil and gas wells• Abrasive formations• High-speed motor applications• Reduces friction on diamond table• Lowers heat generation at cutter/rockinterface• Maintains sharper edge for more efficientdrilling over the life of the run• Increased durability and consistency• Reduced cracking• Enables faster and longer drilling• Maximizes thermal stability

CUTTER TECHNOLOGIESStabilis X Reinforced Cutter Technology
Drill farther in challenging applications

The Stabilis™ X reinforced cutter technology from Baker Hughes amplifies cutter
durability and delivers longer runs in challenging formations. Where traditional
PDC cutters fail, the Stabilis cutter’s novel geometrical design protects the cutterswhile improving performance.
Stabilis cutters introduce a secondary chamfer on the diamond face of the cutterthat enables a higher loading to be applied without breakage. Compared to
traditional cutter geometry, Stabilis cutters have nearly triple the impact strength.
Stabilis cutters also generate less torque fluctuations compared to the standard
geometry. For changing cut depths, Stabilis cutters have a consistent coefficientof friction, whereas standard cutters have a fluctuating torque response.
Controlling these oscillations leads to smoother, more stable drilling resulting inhigher rates of penetration (ROP) and improved overall run performance.

APPLICATIONS• Wide range of challenging formations
where PDC cutter breakage is a concern• Interbedded or directional intervals where
improved torsional stability is required

BENEFITS• Protect the cutter for increased durability
and longer run life
• Reduce spalling and chipping of the
diamond face
• Generate less torque fluctuations with aconsistent response across changing cut
depths• Decrease friction on the cutter face toreduce heat buildup• Reduce cuttings size for easier transport

Drill faster. Drill farther.

The ShockWave™ shaped cutter from Baker Hughes saves time and money byextending cutter life to enable your drill bit to drill faster and farther. Designed
for the Dynamus™ extended-life drill bit platform, novel ShockWave geometry
improves cutter-rock interaction for efficient drilling and increased durability inall applications.
DRILL FASTERThe ShockWave cutter geometry increases stress on the rock, enabling the rockto fracture with less energy. The result is a cutter that drills like a single chamfercutter with the impact resistance of a dual chamfer cutter, resulting in increased
ROP for a given weight on bit (WOB).
DRILL FARTHER
Heat on the face of a cutter causes it to wear and chip faster. The unique shapemoves the rock up the trough and breaks it as it hits the ShockWave feature.
Cuttings are projected away from the face of the cutter resulting in lower heaton the diamond table. Less heat on the diamond table results in longer
cutter life.

APPLICATIONS• Conventional and unconventional oil andgas wells• Abrasive and interbedded formations

BENEFITS• Lowers WOB requirement for a given ROP• Reduces friction on diamond table• Lowers heat generation at cutter/rockinterface• Breaks up rock cuttings to improve

APPLICATIONS

Increasing dependence on directional drilling has resulted in a higher demand for
quality drill bits that provide high levels of reliability, steerability, and performance.
Baker Hughes has addressed these needs with our Vanguard Directional™ rollercone drill bits.

BENEFITSThe new benchmark for drilling directional intervals

Vanguard plug drillout
tricone drill bit

Because traditional roller cones were originally designed to drill vertically, the bits
did not perform at the same levels in diverse drilling environments. For example,
cyclical sideloading intrinsic to directional drilling often led to leg damages andearly seal failures, premature heel-rounding also gave way to early seal failures
and reduced penetration rates, and back reaming damaged bit compensator
systems and increased torque and drag.

Tricone drill bits

Diamond inserts (DX)For directional and highly abrasive applications,diamond inserts deliver unmatched gaugeholding ability. Every third insert has a thicker
diamond table and generous chamfer for
remarkable resistance to breakage.

For abrasive applications where rounded gauge is
a problem, every gauge trimmer is diamond.

Motor hardfacing (M)Center jet (C)Wear/stabilization pad (P)Shirttail compacts (S)Three-port center jet (C3)

For additional wear resistance when drilling
directional or abrasive applications, a tungsten
carbide spray coating can be applied to cones.

For directional and highly abrasive applications,
tough ovoid-shaped inserts are added on the heel
row and a generous amount of carbide inserts areadded on the gauge.

Breakage-resistant heels (H)A breakage-resistance package for tough drilling
applications where friction tends to heat-checkthe heel compacts.

Every heel compact is diamond enhanced.

For maximum gauge and heel-area protection,
every third gauge compact and every gauge
trimmer is diamond.

Wear/stabilization pads are a steel blockcontaining flush-mounted carbide inserts added
to the outer diameter of a bit to minimize wearon the bit leg or body.

STL™ hardfacing is the industry’s leading
technology to strengthen legs and shirttails.

For additional leg protection in abrasive
applications, flat diamond compacts can be
added to the leading edge of the leg pad.

For additional protection in high-speed,
directional, or abrasive applications, motor
hardfacing can be applied. Tungsten carbide
particle hardfacing is applied liberally along
the shirttail and extended up the leading edgeof the bit leg.

Tungsten carbide compacts are added to theshirttail to reduce leg wear in abrasive formations
and deviated or horizontal wellbores.

For additional leg protection in abrasive
applications, flat diamond compacts can beinserted on the leg of the bit.

High-flow extended nozzles are added tomaximize penetration rates in hard and softformations. These nozzles are much sturdier andprovide greater flow capacity than conventional
extended nozzles.

A fourth jet may be positioned in the center ofthe bit. Center jets are primarily used to prevent
bit balling and the associated reduction in
penetration rate. Center jets are available in bit
sizes 7 7⁄8-in. and larger.

For bit sizes 16-in. and larger where severe balling
conditions may occur, three fixed ports can bepositioned in the bit center.

metallic zinc or 60 by weight of finely powdered lead, with not more than 0.3 total active sulfur (reference the caution regarding the use of hazardous
materials in Appendix F of Specification 7) applied thoroughly to all threads and shoulders and using the modified
Screw Jack formula in Appendix A, paragraph A.8, and a unit stress of 62,500 psi in the BOX or PIN, whichever is weaker.

diameter and bore, i.e., 23⁄8-in. API IF, API NC 26, and 27⁄8-in. slimhole connections used with 3½ in. x 1¼ in. drill collars all have the same minimum
makeup torque of 4,600 ft/Ib, and the BOX is the weaker number.
