Challenge

Hole Opening

Delivering consistent performance and still drilling

In a vertical drilling application, a P11FH premium roller cone bit drilled from 1,225m MD to 1,702m MD to TD the interval in 65.1 hours, resulting in an average penetration rate for the area.

The cutting structure on the bit exhibited minimal wear and the hardfacing was still in good condition. Further, the cone rotation resistance suggested the seals were in “like new” condition and the client has since run this bit several more times, accumulating well over 100 hours of operating time and far more than 1,000,000 revolutions.
