The present disclosure relates to the field of drilling equipment for the discovery and production of hydrocarbons from the earth. In particular, this disclosure relates to a torque reaction device for coupling a pipe running tool to a top drive assembly on a drilling rig. In one embodiment, a system for coupling a pipe segment to a pipe string includes a top drive assembly, a pipe running tool, and a torque reaction device. The top drive assembly includes an output shaft and a link extending from the top drive. The top drive is operative to rotate the output shaft with respect to the link. The pipe running tool is coupled to the output shaft and is engageable with a pipe segment to transmit torque from the output shaft to the pipe segment. The torque reaction device couples the pipe running tool to the link.

Torque reaction device for pipe running tool

Generally, the present disclosure is directed to wellbore tubular running systems and methods of their use. In one illustrative embodiment, a tubular running system is disclosed that includes, among other things, a torque frame, a main shaft extending through a top opening of the torque frame and rotatable by rotation apparatus, slip setting apparatus connected to the torque frame and including a levelling beam and a plurality of slip assemblies, each of the slip assemblies connected independently and pivotably to the levelling beam, and movement apparatus connected to the levelling beam for moving the slip assemblies in unison with respect to a tubular projecting into the torque frame.

Tubular running tool and methods of use

An elevator having, in at least certain aspects, an elevator body with two opposed ends and an elevator opening in the body, a door pivotably mounted to the body for selectively closing off the elevator opening, a lock bar on the elevator body, door latch apparatus on the door including a movable member to selectively and releasably hold the lockbar, and locking apparatus for selectively locking the door in position; and, in certain aspects, verification apparatus for maintaining the locking apparatus in position.
