Counterforce Oil Drill Bit

Ulterra Continues to Expand the Application for CounterForce®

Ulterra Drilling Technologies continues to expand the application for its groundbreaking CounterForce® cutting structure technology.  CounterForce uses the cutting structure to reduce vibrations at the bit, which increases efficiency and reduces bit damage.  Reducing vibration is particularly important on wells which utilize Rotary Steerable Systems (RSS), which are becoming more popular as well planners are pushing the limits on directional difficulty and lateral lengths.

FastBack PDC bit oil and gas

Oilfield Technology June 2014

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.
