Reverse Pro® Mandrel

Rotating, reciprocating slick mandrel

The CleanWell® Reverse Pro® mandrel is designed to assist in reverse-circulating (or forward circulating on a choke) applications where rotation and reciprocation is required. The high-pressure proprietary seal system allows reverse-circulating pressures to be managed at the surface. With the static outer mandrel, stripping pipe through the annular blow out preventer during the rotation and reciprocation sequence is no longer required. The tool is designed to take advantage of high drillpipe velocities without having to sacrifice the enhancements of pipe movement while circulating.
