A tubular handling apparatus including a tubular member running tool adapted to provide load-bearing, and preferably torquing, capacity upon the gripping of a tubular is provided. The running tool includes a slotted member having a plurality of elongated slots, a recessed member associated with the slotted member and having a plurality of recesses, and a plurality of gripping elements disposed between the slotted member and recessed member. Each such gripping element is adapted to move with an engaged tubular so as to grip the tubular. A tubular member elevator associated to the running tool, as well as related floor slips, are also encompassed. Methods of casing running are also included.

Tubular handling device and methods

Tubular handling methods

A tubular member handling apparatus including a tubular member running tool, an elevator, first actuators each extending between the running tool and the elevator, and second actuators each extending between the running tool and a corresponding first actuator. The running tool includes a slotted member having a plurality of elongated slots, a recessed member slidably coupled to the slotted member and having a plurality of recesses, and a plurality of rolling members each retained between one of the recesses and one of the slots. Each rolling member partially extends through an adjacent slot when located in a shallow end of a corresponding recess, and retracts to within an outer perimeter of the slotted member when located in a deep end of the corresponding recess.

Apparatus and methods for measuring in-situ applied torque in tubular operations. A torque cylinder has a first end and a second end. A torque rod is at least partially contained in the torque cylinder and is coupled to the first end of the torque cylinder. The torque rod extends longitudinally outward from the second end of the torque cylinder. A strain gauge is connected to the torque rod at a predetermined distance from the first end of the torque cylinder. The strain gauge is configured to measure in-situ the applied torque between two tubular drill string segments each coupled to a respective one of the torque cylinder and the torque rod.

Real time torque system

A tubular handling apparatus comprising a slotted member having a plurality of elongated slots each extending in a direction, a recessed member slidably coupled to the slotted member and having a plurality of recesses each tapered in the direction from a shallow end to a deep end, and a plurality of rolling members each retained between one of the recesses and one of the slots, wherein each rolling member partially extends through the adjacent slot when located in the shallow end of the recess, and wherein each rolling member retracts within an outer perimeter of the slotted member when located in a deep end of the recess. The apparatus may further comprise a plurality of biasing elements each biasing a corresponding one of the rolling members towards the shallow end of the corresponding recess.

Tubular handling device

A gauging device and method for use in coupling threaded tubular articles including tubes and couplings. The device and method provides for the use of gauges for the tube and coupling that provide markings thereon that when in register during coupling indicate when a preselected threading distance has been achieved. A coupling assembly is provided that employs an annular gasket attached to the coupling and adapted to be deformed by the end of a tube when inserted into the coupling to provide sealing.
