ULTERRA Design Engineering
3D Solid Modeling Design - Ulterra design engineers use
3D modeling design tools (CAD) to accelerate design and to
insure that high quality precision is built into every bit. Once the
designer’s intent is verified, an automated process creates the
drawing packages for production. This state-of-the-art design
tool guarantees unmatched precision and design repeatability
for a bit built now or in the future.
Computational Fluid Dynamics - To reduce the tendency
for bit balling and to reduce erosion of the bit body, Ulterra
Engineers utilize CFD analysis to balance fluid flow , cutter
cooling and erosion in each of their bit designs.
Blade Strength Calculation - Each bit design undergoes a
mathematical process to optimize blade strength and geometry.
Physical & geometrical characteristics of each blade are
adjusted to optimize blade integrity and cuttings flow.
Work Curve Analysis - Each bit undergoes an analysis of
individual cutter work load to reduce cutter imbalance. Cutter
configuration is then designed to distribute work evenly among
the cutters to increase a bits drilling efficiency.
Ulterra engineers employ the very latest technol
gies, including advanced computer-aided design
(CAD), to develop reliable bits that consistently
meet and exceed customer requirements.

ULTERRA PDC Cutter Technology
ULTERRA Ulterra U-Technology
6
CounterForceTM
A patent pending PDC bit technology which utilizes a unique cutter configuration to lower bit reactive torque and vibration, dramatically improving drilling efficiency. Unlike traditional PDC bits, the cutters of this step-change advancement work together to lower lateral vibration and increase crack propagation. The CounterForce cutting structure is engineered to slice through rock while maintaining a more consistent torque signature thus increasing stability and ROP.
• Reduced torque and vibration
• Improved drilling efficiency
• Improved directional performance
• Higher ROP
FastBackTM
FastBack’s unique shape gets the blade out of the way and the cutters deep into formation. Instead of limiting PDC bits by the weaknesses of the materials, FastBack strategically aligns their strengths, each component enhances the others. The body material maximizes strength without restricting the cutting action or evacuation. Advanced surface coatings provide maximum erosion control without sacrificing strength. Hydraulic pathways have ultimate flexibility to enable extreme ROP. All of which converge on driving all available drilling energy into premium diamond cutters application optimized through Ulterra’s industry-leading LightSpeed™ cutter testing program. The result—another stepchange in Ulterra’s front-running reliability and ROP.
• Energy focused on the cutters drills faster with lower WOB
• Wide open blade structure provides optimal hydraulics
• Quality-focused design and process ensures industry-leading reliability
• Materials used deliver consistent performance
Ulterra’s “U-Technology” brand represents our commitment to
be a top performer in every field we operate. We achieve this
performance by focusing our applications engineering teams
on a district level to insure continuity of local knowledge and
decrease the time it takes to bring a solution to the field.

OneShotTM
Ulterra’s OneShot designated bits are designed specifically for curve and lateral applications to reduce drilling time and hit precise directional targets without unnecessary bit-trips. OneShot bits have been proven in their specific applications to save operators money and reduce risk by reliably achieving build rates.
• Reduced drilling time in the curve
• Decreased risk of bit trips
• Excellent directional control
SplitBladeTM
SplitBlade looks different because it is different. The physical disruption of the typical straight blade keep cuttings separated through evacuation to keep the cutting structure clean. Dedicated hydraulic flow to physically separated portions of the cutting structure sweeps cuttings down the junk slot, reducing the risk of balling up in the bit.
• Dedicated flow to troublesome areas
• Reduce risk of balling
• Improved cuttings evacuation
Heavy Oil Grade SeriesTM
Heavy Oil Grade matrix body PDC bits are designed to drill long distances with excellent steerability, repeatability and backreaming capability. The bit’s abrasion-resistant, XT cutters optimize diamond exposure to the formation to protect the bit body; improve ROP, and enable the bit to remain in the hole longer. Enhanced hydraulics and a step-down feature behind each blade prevent sand and debris build-up and help ensure accurate steerability over the entire lateral length, even in the most unconsolidated sands. A strengthened gauge pad and robust backreaming feature ensure trouble-free backreaming while maintaining the original gauge diameter specifications.
• Abrasion resistant
• Higher ROP
• Enhanced steerability

ULTERRA Inertia™ Friction reduction Tool
11
• Reduced reactive torques
• Improved tool-face control
• Faster ROP
• Added lateral vibration to drill string enhances weight transfer to bit and drilling efficiency
• Lower pressure drop allows utilization of multiple tools
• Zero mud pulse eliminates MWD frequency interference
• Robust design and all metal construction insures industry leading operating life and high temperature capability
The INERTIA tool generates lateral vibration into the
drill string to reduce friction. Its ability to add friction-
reducing vibration into a drill string can enhance weight
transfer to the bit, alleviate torque and drag effects in
the string and aid in drilling efficiency.
The INERTIA tool requires a much lower pressure to operate, up to ten times lower pressure
drop than competitive tools. Thanks to INERTIA, running multiple vibration tools at problem
areas throughout your drill string is possible. Its unique design generates energy without
restricting pressure pulses, eliminating concerns with MWD frequency interference. In addition,
its robust all-metal construction will provide industry leading operating life.
In today’s extended reach highly deviated drilling applications, the complexity of the well path
and increased drill string friction often impede a driller’s ability to drill efficiently. The inability to
slide, drill fast and achieve targets cost time and money. The fully compatible INERTIA Tool
stimulates the drill string, increasing drilling efficiency and extending reach in lateral intervals.

ULTERRA PDC Dull Grading
1: Inner Cutting Structure
2: Outer Cutting Structure
3: Primary Dull CharacteristicBC – Broken Cutter*BT – Broken Teeth*BU – Balled upCR – CoredCT – Chipped Teeth/CuttersDEL – Delaminated CutterER – ErosionHC – Heat CheckingJD – Junk Damage LT – Lost Teeth/CuttersPN – Plugged NozzleRO – Ring OutSP – Spalled CutterWO – Wash OutWT – Worn Teeth
4: Location of Primary CharacteristicWhen the primary dull characteristic has been determined, enter the main location of this characteristic. For example, if WT is the primary dull condition and it occurred mostly on the shoulder on the bit, enter S into the field.
A – All Areas C – Cone G – Gauge N – Nose S – Shoulder
The inner cutting structure consists of the inner 2/3 of the bit diameter whereas the outer consists of the final 1/3. A general rule of thumb is the inner number represents the cutters inside the nose and the outer represents those outside.
5: Bearing Seals (XXX for PDC. Only used for roller cone)
6: Amount Under GaugeThe gauge section of the dull grading system is represented by either IN or an integer representing 1/16” under gauge beginning at number 1.
IN means that the bit is still at full gauge.A value of 1 equals 1/16” under gaugeA value of 2 equals 1/8” under gaugeA value of 3 equals 3/16”, etc...
7: Other / Secondary Dull Characteristic In cases where there are multiple dull characteristics present on a bit, the “other” field can be used.After the primary dull characteristic has been determined, find the secondary condition and enter its code in the field. If there is no other dull condition, enter NO into the field.
