Abstract

See full text

Systems and methods for reducing the amount of torque transferred to the Bottom Hole Assembly and the drill string during drilling operations are disclosed. The drill string includes an optionally non-rotatable portion. A rotational hold down system is positioned at a first position on the drill string where it is not rotationally coupled to the drill string. The rotational hold down system is then moved to a second position on the drill string where it is rotationally coupled to the optionally non-rotatable portion of the drill string. In the second position, one or more bars on the rotational hold down system substantially prevent rotation of the optionally non-rotatable portion of the drill string.
