Drill bit design redirects vibration, increases drilling rates

Since vibration is inherent to drilling, Ulterra has developed a bit design that takes advantage of the vibration to increase drilling rates and sustain a sharper bit for longer intervals. Aron Deen, the company’s product engineering manager – global, explains the design philosophy behind CounterForce, which was showcased at the 2013 ATCE in New Orleans, La., last week. Since the technology was commercially launched in July, approximately 500 wells – more than 2.5 million ft – have been drilled with CounterForce applied.
