Abstract
A mandrel harnesses torque from a progressing cavity pump stator to which it is coupled. Operation of the pump rotor induces a torque on the pump stator, and that torque is harnessed by the mandrel. A rate of rotation of the mandrel due to the torque from the pump stator is controlled, and the rotation rate is hydraulically reduced in an embodiment. A rotation in a direction opposite to a direction of rotation of the mandrel due to the torque from the pump stator is applied to a production tubing string. The direction of rotation of the mandrel could be reduced and applied to the production tubing string by a planetary gear system, for example.
