Case Study: CNX Resources achieves 100% in-zone drilling and faster curve-and-lateral completion with SLB NeoSteer CL System

NeoSteer CL System Drills Curve and Lateral Sections in a Single Run Over 2 Days, Maintaining 100% in Zone

CNX Resources worked with SLB to find a faster, lower-cost way to drill curve and lateral sections in its Northeast Basin well program. The company wanted a single-run solution that could maintain high ROP while preserving azimuthal control, hole quality, and a smooth wellbore for later casing, wireline, and frac operations.

SLB recommended the NeoSteer CL curve and lateral at-bit steerable system, paired with a HyperBlade hyperbolic diamond element bit, to drill both sections in one run. The result was 100% in-zone drilling over 8,114 ft MD in a single day, reaching TD in 2 days with an average ROP of 308 ft/h, 126 ft/h in the curve, 460 ft/h in the lateral, and more than 700 ft/h instantaneous ROP, while keeping tortuosity to 0.55°/100 ft.
