Drill curve and lateral in a single run, reduce emissions.
In Argentina, operations are a significant challenge because of formation complexity. This complexity increases shocks and vibration and causes high erosion because of heavy mud weight and high temperature across the end of the lateral section. YPF wanted to improve ROP, reduce tortuosity, and drill a single extended-reach well in one run. The objective was to reduce the time to drill the wells by considerably improving the ROP and the drilling efficiency.
A conventional rotary steerable system (RSS) BHA produced low ROP, high tortuosity, and directional control problems, leading to multiple runs.
The NeoSteer CL system is specifically designed to enable drilling the curve and lateral in a faster single run. Schlumberger recommended the NeoSteer CL system. As a result, the autonomous downhole control system (auto-tangent) feature delivers low tortuosity and better hole quality.
YPF, Chevron, Nabors, and Schlumberger set the longest well drilled record by drilling the 81/2-in production section of 4,155 m lateral well in less than 31.1 days, completing well-construction operations in the Loma La Lata field.
