Torque and Drag: 1.0-3.0% by volume. Maintenance is achieved by adding 0.5- 1 drum per 24 hour period or as needed to achieve lubricity goals or to increase ROP.
Sliding Pills: 3-5% by volume can be added directly to the suction pit or sent in sliding pills to reduce torque and increase ROP
Stuck Pipe: Can be spotted in its concentrated form (if density is not a safety concern) across the zone where drill pipe is stuck. Sufficient soaking time should be allowed while tension and torque is applied to the drill string and worked up and down to free the stuck pipe.
