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.
A system for coupling a pipe segment to a pipe string, comprising:
A pipe running tool for use with a top drive assembly, for handling pipe segments and for engaging pipe segments to a pipe string, comprising:
A method for reacting torque applied to a pipe running tool in a drill rig having a top drive assembly, the method comprising:
