A major operator in Argentina working with SLB implemented the NeoSteer CL™ curve and lateral at-bit steerable system (ABSS) with autonomous downhole control features to build the challenging curve and lateral sections. Drilling was completed in a single run, avoiding vibration, and a second trip to change out the BHA. As a result, the operation eliminated 1.5 days, saving USD 97,000.

The onshore formation demanded overcoming vibration and jamming in an environment with high mud density and solids. The operator faced additional risks, including curve and lateral sections with high dogleg severity (DSL). The goal was to navigate through two levels to achieve TVD in one run.

SLB recommended the NeoSteer CL curve and lateral ABSS with auto-curve and auto-tangent enhancements. A drilling parameters road map was designed to optimize ROP. The crew drilled 5,000 m in eight days, from casing shoe-to-well TD at 7,228 m. Operator successfully geosteered 3,964 m in the lateral section passing through two geological layers with 100% accuracy on target in the pay zone. By improving efficiency in this high-density, high-solids environment, the BHA reached TD in one run. With no NPT, the project saved an estimated USD 97,000.
