Background
An operator on Sakhalin Island needed a circulating valve to boost annular velocities for hole cleaning during drilling operations. M-I SWACO recommended positioning the WELL COMMANDER ball-activated drilling circulating valve above the drilling BHA to mitigate drilling hazards and to boost annular velocities as required. The high pump rates and annular velocities achieved were made possible by pumping weighted pills through the valve ports and the improved hydraulics provided by the valve.
