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,
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.
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.
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.
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.
