Case Study: Chesapeake Energy achieves higher footage per bit and ROP with SLB’s EnduroBlade 360 bit

Chesapeake Improves Footage per Bit and ROP in Abrasive Formation with EnduroBlade 360 Bit

Chesapeake Energy was looking for a more efficient way to drill the 6⅛-in. horizontal lateral section of Oklahoma’s abrasive Colony Wash play. The company wanted to increase footage per bit and reduce trips out of hole while keeping ROP at a reasonable level to lower overall well cost, and worked with SLB using EnduroBlade 360 rolling diamond element bits.

SLB recommended EnduroBlade 360 bits with 16-mm cutting elements, designed with the IDEAS integrated dynamic design and analysis platform to better withstand abrasion and maintain cutting efficiency. Across three wells, the solution increased footage and ROP, including a lateral drilled 2,885 ft at 21.1 ft/h and another drilled 4,175 ft at 23.3 ft/h, which was a record ROP for the Colony Wash play; Chesapeake Energy said it would continue running the 16-mm EnduroBlade 360 bits on future wells.
