NitroForce® High-Flow, High-Torque Motor Drills Curve 37% FasterDownload PDF
Deliver a one-run curve section of an unconventional well
Williams County, Bakken, North Dakota
An operator challenged the Halliburton Sperry Drilling team to deliver a one-run curve section of an unconventional well in 12 hours or less. By collaborating with the operator on the bottomhole assembly design, the Sperry Drilling team engineered a drilling solution utilizing the NitroForce® high-flow, high-torque motor with 0.40 revolutions-per-gallon and a 2.25-degree fixed bend housing specifications. This design achieved consistently high horsepower while maintaining high differential pressure. The curve was drilled successfully in 7.5 hours at an average 15.85-degrees/100 ft. dogleg severity. It is 37% faster than originally planned. The entire section was drilled in 16-1/2 hours, significantly reducing well time and maximizing the value of the asset.
