Abstract:
A method for converting a kelly rig for handling casing includes the formation of a torque reaction guide with elongate members available at a drill site including for example, any of drill collar stands, casing strings, drill pipe stands and cables held in tension. A method for converting a kelly rig for handling casing may include the step of installing a torque reaction guide in a simple way, such as by securing the track to the monkey board. In one embodiment a torque reaction frame is used for securing between a torque generating device and a torque reaction guide that operates in a float mode to allow for misalignment of the torque reaction guide relative to the well hole center.
