American Oil & Gas Reporter April 2015

As seen in the American Oil & Gas Reporter in the April 2015 issue, Casey Dalla Betta and Aron Deen speak about Ulterra’s response to the evolving needs of an industry focused on drilling deeper targets and longer laterals more efficiently and safer than ever. Whatever the target reservoir, the success of any bit design can be measured in three words: steerability, durability and speed. Success in each of these measures is what Ulterra’s OneShot technology is all about.

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.

Featured in Oilfield Technology: Aron Deen and Casey Kitagawa, Ulterra Drilling Technologies, Barry Schneider and Gary G. King, Shell, explain how new advances in PDC bit construction and design are helping to cut drilling costs in the Marcellus Shale. One of the key contributors to the improved performance and the primary differentiator of the FastBack™ steel body PDC bit design is the specialized geometry, which is designed to enhance the delivery of mechanic specific energy (MSE) into the rock. The new blade top geometry allowed Ulterra to simultaneously increase both potential top-end ROP and durability.

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 is a leading provider of premium drill bits and downhole tools for the oil and gas industry. Its strength resides in the experience and wisdom obtained from industry veterans, designing high-quality, high-performance PDC bits for global markets. Its localized focus enables Ulterra to respond quickly to customer’s specific applications with highly innovative and customized solutions.
