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.
