Wellbender’s 150°C MWD System

The low-maintenance Pilot MWD System is designed for simplicity of operation and assembly, and convenient transportation. Built to perform in difficult drilling environments, the Pilot MWD System can operate in temperatures up to 150° C and pressures up to 20,000 psi. The positive-pulse retrievable and reseatable tool accommodates a number of probe configurations, ensuring top performance in a variety of flow ranges in collar sizes from 3½ O.D. to 12″ O.D. This modularity, combined with the Pilot MWD System’s rugged and retrievable design, minimizes rig downtime and reduces financial risk.
