Abstract
A wellbore tubular handling system for applying a downforce to wellbore tubulars using a service rig. A downforce system includes a first frame assembly coupled to a slip assembly for engaging wellbore tubulars, a base member connected to the first frame assembly, and an actuator adapted to extend and/or retract the first frame assembly between a first position and a second position, wherein the second position is laterally displaced from the first position along a path formed by extension of the actuator, and wherein the base member is connected to the mast of the service rig. A method of applying a downforce to a wellbore tubular using a downforce system for a service rig.
Claims25
A portable downforce system comprising,
- a first frame assembly coupled to a slip assembly for engaging wellbore tubulars,
- a base member connected to the first frame assembly, and
- an actuator configured to extend and/or retract the first frame assembly between a first position and a second position,
- wherein the second position is laterally displaced from the first position along a path formed by extension of the actuator, and
- wherein the base member is connected to a mast of a service rig.
A method for moving wellbore tubulars into or out of a wellhead, the method comprising,
- positioning a travelling slip assembly in line with a center of the wellhead,
- feeding a tubular through the travelling slip assembly;
- applying a downforce or an upforce using the travelling slip assembly to push the tubular into or pull the tubular out of the wellhead;
- and
- retracting the travelling slip assembly so that it is no long in line with the center of the wellhead when not in use.
