Abstract: The disclosure provides a torque release tubing rotator comprising a rotator body and a split drive mandrel rotatably coupled to the rotator body. The split drive mandrel receives and engages at least a portion of a tubing hanger. The split drive mandrel comprises an outer driven portion, an inner mandrel portion, and a one-way locking mechanism coupling the outer driven portion and the inner mandrel portion. The disclosure also provides a torque release tubing hanger for a tubing rotator comprising an outer housing, a tubing mandrel suspended from the outer housing, and a locking swivel rotatably coupled to the outer housing. The locking swivel is movable between a locked configuration and an unlocked configuration. A bi-directional coupling is also provided. The disclosure also provides a torque release tubing rotator system comprising the tubing rotator and tubing hanger.
Abstract: There is provided a rotating split tubing hanger, including: a mandrel having a bore therein and a mandrel exterior surface, the mandrel attachable to a tubing string; a housing sleeve mountable on the exterior surface of the mandrel, the mandrel being rotatable relative to the housing sleeve, and the housing sleeve comprising a housing sleeve exterior surface; and an outer sleeve removably mountable on the housing sleeve exterior surface, the outer sleeve comprising an outer sleeve exterior support surface engageable with a tubing head.
Abstract: Sealing/locking rod safety clamp systems and components are provided. In some embodiments, the systems can comprise a locking rod clamp, a lockable drive motor shaft, and locking shaft rams. Methods of use of sealing/locking rod safety clamp systems and components are also provided.
Abstract: Tubing string rotators, safety rod clamps, combination tubing string rotators and safety rod claims, and rotating split tubing hangers are provided. The tubing string rotator can rotate a tubing string suspended in a hydrocarbon well from a rotatable support mandrel. The support mandrel can be positioned at the well head and can be supported against downward axial movement. The tubing string rotator can comprise a motor for producing a rotational force, a drive assembly for applying the rotational force to drive the rotation of the support mandrel, and a controller operatively connected to the motor for intermittently activating the motor, causing rotation of the support mandrel, for selected intervals of time, followed by selected intervals of time of motor inactivation, in which no rotation of the support mandrel occurs. Intermittently or non-continuously rotation of the tubing string can result in more even wear and/or erosion of the tubing string.
