ABSTRACT:
A tubing rotator assembly that attaches to a casing head to suspend and rotate a tubing string in an oil well. The tubing assembly includes a rotation surface, such as a bearing, in which a tubing mandrel rests and allows one to rotate the tubing manually above the wellhead, and a mandrel bowl that rests inside the casing head. A tubing mandrel is partially contained within the mandrel bowl with one end exiting the bowl and attached to the tubing string, and the opposite end exiting the top of the bowl. A ledge of the tubing mandrel is supported on the bearing, which bearing rests on the interior ledge of the mandrel bowl. The assembly provides a low profile reducing the distance between the casing head and the pumping tee to eliminate the need to raise the pumping unit to fit on the rotator.
