SPE/IADC Aligned Materials and Design Development of High ROP Drill Bits

Ulterra’s Development Leader, Aron Deen, presented at the Asia Pacific Drilling Technology Conference. His presentation was in regards to aligned materials and design development of high ROP drill bits. Aron’s presentation will give you a better understanding of the history and drivers of PDC design and manufacture, the realization of material strengths through design, and an inside look at the Marcellus Shale.


American Oil & Gas Reporter April 2014

As seen in American Oil & Gas Reporter in the April 2014 issue, Aron Deen speaks about the CounterForce™ cutter configuration technology. In the endless quest for faster penetration rates, longer runs and better steerability, manufacturers have introduced cutter configurations that counter vibration; bits that drill a small hole to relieve rock stress, then widen the hole to the desired diameter; and designs that turn conventional wisdom on its head by increasing ROPs with smaller cutters. Consider Ulterra’s CounterForce™ cutter configuration, which engineering project manager Aron Deen says originated from machining. “We decided to see what would happen if we adapted the tool’s staggered tooth concept to a drill bit. Because the tool reduces vibration, we hypothesized the bit would offer increased durability and higher penetration rates.” That hypothesis was proven correct. The ROP increase varies by application, but generally falls within 10-50 percent. “Because it involves rearranging components rather than using experimental parts, the bit costs the same as its predecessors and the operator’s risk is extremely low.”


Ulterra introduces high ROP PDC bit

FORT WORTH, Texas, Nov. 11, 2013 /PRNewswire/ — Ulterra announced today the availability of PDC bits incorporating the next generation FastBack technology.

Unlike traditional PDC bits, FastBack designed bits utilize a unique blade configuration that supports the cutters in a minimalist fashion. Its smaller profile eliminates wasted energy pushing a bit’s blade surface, focusing all energy on the diamond cutting surfaces. This efficiency improvement is already paying operators dividends where a Fastback bit drilled a Marcellus well 56.8% faster.

The FastBack’s new innovative blade design is possible thanks to advanced surface coatings which provide maximum erosion control without sacrificing strength. Additionally, The FastBack’s smaller blade configuration opens up the junk slot area for optimal hydraulics and enhanced cuttings evacuation. “FastBack is Ulterra’s latest breakthrough in PDC technology. It embodies advanced materials, design and manufacturing to achieve superior speed, efficiency and quality,” said Aron Deen, Engineering Project Manager.

Ulterra introduces CounterForce

FORT WORTH, Texas, April 21, 2013 /PRNewswire/ — Ulterra today announced the introduction of CounterForce, a breakthrough in PDC bit design technology that utilizes a unique cutter configuration that lowers bit torque and vibration, thus creating more efficient failure of rock. Unlike traditional PDC bits, the cutters of this patent-pending, step-change advancement in new PDC technology 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. CounterForce technology improves drilling efficiency and is being incorporated into many Ulterra PDC designs.

Early field runs have shown CounterForce-designed U519M bits drilling with improved toolface control and sliding ROP. In an Eagle Ford tangent drill-out interval, a CounterForce bit set a rig ROP record drilling 41% faster than the closest offset, saving the operator 15 hours and $50,000. In a Permian Basin Wolfcamp lateral, a CounterForce run finished the lateral a dramatic 42% faster ROP than direct offsets, saving the operator an entire day of drilling. Hundreds of field tests, drilling nearly a million feet in multiple applications and plays across North America, validate that CounterForce technology consistently reduces torque and vibration problems and improves directional performance and dull conditions.

ESCO Corporation, a leading designer and manufacturer of highly engineered wear products for the mining, infrastructure, power generation, aerospace and industrial industries, today announced that it has completed the previously announced acquisition of all the outstanding equity interests of Ulterra Drilling Technologies, L.P. for $325 million in cash.

Headquartered in Fort Worth, Texas, Ulterra designs and manufactures polycrystalline diamond compact drill bits used in the construction of oil and gas wells. The acquisition of Ulterra provides ESCO with entry into the oil and gas industry and complements ESCO’s existing businesses in the development of wear solutions.

“At ESCO, we are looking for businesses that share our strategy of providing customers with highly engineered, quality wear parts and solutions,” said Cal Collins, President and CEO of ESCO Corporation. “Today, we add Ulterra as a strong and important part of our growth strategy. Its product offering and expanding global presence makes it an ideal addition to ESCO. Ulterra has an exceptional team and culture and shares ESCO’s customer focus and commitment to quality.”

As part of the acquisition, more than 400 people will join ESCO. Ulterra has manufacturing operations in Fort Worth, Texas and Leduc, Alberta, Canada. Ulterra will operate as a division of ESCO and Johnny Everett will continue to lead the organization as division President


Expansion into the Gulf Coast and Gulf of Mexico

Ulterra has opened a new stock point in Hammond, LA.  The new center is strategically located just 46 miles east of Baton Rouge and 58 miles north west of New Orleans and will support drilling activity in Mississippi, Alabama, South Louisiana and Gulf of Mexico.  Ulterra’s new Gulf coast operations will be led by Rob Smith, an experienced and respected drill bit supplier.  He will oversee the new location, which will offer a full line of matrix and steel body PDC bits designed specifically for Gulf Coast applications.  Staffing the Hammond stock point will be experienced personnel with an intimate knowledge of local drilling.  Utilizing the latest analytical tools, the Ulterra staff will ensure all customer requirements are clearly understood and the correct bits are applied to optimize their operations.  In addition, Ulterra will soon open a stock point in Lake Charles, LA.  With the addition of the Hammond and Lake Charles stock points, Ulterra now has six people, each with over 30 years of experience, supporting our customer’s Gulf Coast and Gulf of Mexico operations.
