Featured in the October issue of World Oil magazine, Ulterra discusses PDC bits for RSS applications.
To extract the full potential of different RSS types, operators have sought out drill bit manufacturers, to provide designs tailored to specific parameters and BHAs. Ulterra has utilized its proprietary technology to develop CounterForce™ PDC bits, designed specifically to reduce lateral vibrations, a leading cause of downhole tool failure.
Nearly all new technologies struggle in their infancy to gain adoption due to high cost, problematic reliability, lack of understanding, and marginal value proposition. Over years of learning, development and refinement these hurdles reduce, and with each step new opportunities open up. This has been the case for rotary steerable systems (RSS), which is finding new value in this historic downturn.
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.
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,
