• Soft formation
  • Build up rate off target
  • Required azimuthal turn
  • Risk of missing target
  • Saved the run
  • Achieved build up rate of 17°/100 ft
  • Completed 45-50° azimuthal turn
  • Improved steerability without compromising ROP

Case study details

Our customer in West Texas was experiencing difficulties drilling the 8.5-in. curve section in the soft formations of the Delaware Basin. They had built the curve to 20 degrees with the competitors PDC bit, but only at a rate of 7°/100 ft. The remainder of the curve required a build up rate of 17°/100 ft and completion of a 45-50° azimuthal turn to avoid a lease line and land on target.
