Abstract
A system including a stabbing guide with a plurality of guide elements, an engaging element, and a linkage assembly that couples the plurality of guide elements to the engaging element, where rotation of the engaging element relative to the plurality of guide elements drives the linkage assembly and, via the linkage assembly, moves the guide elements radially relative to a center axis of the stabbing guide.
Claims20
A system for performing a subterranean operation;
- the system comprising:
- a stabbing guide comprising:
- a plurality of guide elements;
- an engaging element;
- and
- a linkage assembly that couples the plurality of guide elements to the engaging element;
- and
- wherein rotation of the engaging element relative to the plurality of guide elements drives the linkage assembly and, via the linkage assembly, moves the guide elements radially relative to a center axis of the stabbing guide.

A system for performing a subterranean operation;
- the system comprising:
- an iron roughneck comprising a torque wrench and a backup tong;
- a stabbing guide comprising:
- a plurality of guide elements;
- an engaging element;
- and
- a linkage assembly that couples the plurality of guide elements to the engaging element;
- and
- wherein rotation of the torque wrench selectively engages the engaging element and rotates the engaging element relative to the plurality of guide elements, and wherein rotation of the engaging element drives the linkage assembly and, via the linkage assembly, moves the guide elements radially relative to a center axis of the stabbing guide.
6 more elements
A method for performing a subterranean operation, the method comprising:
- moving a tubular into an opening in a torque wrench of an iron roughneck;
- rotating the torque wrench, thereby activating a stabbing guide;
- engaging the tubular with a plurality of guide elements of the stabbing guide in response to rotating the torque wrench;
- and
- moving the plurality of guide elements radially inward toward a center axis of the stabbing guide a radial distance that is proportional to a distance of rotation of the torque wrench.
