American Oil & Gas Reporter April 2016

As seen in the American Oil & Gas Reporter in the April 2016 issue, Ulterra discusses recent success when partnering with rotary steerable companies to match our bits to their tools. Adding CounterForce® to customized bit designs reduced drilling vibrations and increased ROP on both PowerDrive and AutoTrak™ systems.

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.

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.”
