TerrAdapt Adaptive Drill Bit Mitigated Stick-Slip, Increased Efficient Drilling Time by 45% and Boosted ROP by 27%

Location: Delaware Basin, Texas

An operator in Reeves County, Texas was experiencing erratic drilling performance in 12¼-in. intermediate sections running through interbedded shale, limestone, and salt. Extremely high torque fluctuations and stick-slip were affecting drilling efficiency, and downhole tool failures were driving up NPT and costs. Looking to minimize downtime and complete the next sections as quickly as possible, the operator contacted Baker Hughes.

Based on the operator’s challenges, Baker Hughes proposed using a TerrAdapt™ adaptive drill bit to improve drilling performance and reduce non-productive time by proactively mitigating stick-slip and impact loading. It incorporates self-adjusting depth-of-cut (DOC) control elements to mitigate torsional instability—which can lead to stick-slip—and to absorb sudden impact loads from formation variations. The bit limits DOC when sudden loading is experienced at the bit face, and increases DOC during smooth drilling to maximize ROP.
