ABSTRACT:
A conduit gripping tool such as a packer or hanger is provided for use in subterranean wells, together with a running tool and a method for installing the gripping tool in the well. Threaded means are mounted on the running tool for axial movement. The hand of such threads is in the opposite direction to the hand of the threaded connections of the work string supporting the running tool. The running tool additionally incorporates dogs which are engagable with slots provided in the gripping tool. A slip mechanism is retained against radial expansion during run-in. The dogs carried by the running tool are aligned with the slots in the hanger body for release so that torque in the same direction as the hand of the threaded connections of the work string is transmitted directly to the body of the hanger. Subsequently, an axially downward force applied by the work string will effect the setting of the slips and the concurrent disengagement of the dogs of the running tool from the body portion of the hanger. A further rotation of the work string in the same direction of the hand of the work string threaded connections will produce an unthreading of the nut carried by the running tool from the hanger body.
