Abstract

In one aspect a rotating hanger comprises a dognut sleeve having a bore and an outer profile compatible for support in the casing bowl and sealing thereto and a tubular hanger mandrel fitted rotatably to the dognut sleeve's bore and having an upper shoulder projecting above the dognut sleeve for interaction with casing bowl holddown screws which, when engaged, restrain rotation and prevent ejection from the casing bowl. In another aspect, an improved well tubing rotator and hanger system is provided the rotatable tubing hanger, a tubular connector sub threaded to the hanger mandrel and a rotator splined to the connector sub, the splined connector sub enabling rotational coupling without imposing hanger loads into the rotator which enables use of smaller, low profile and economical rotators. In another aspect, a rotator having a threaded nozzle wellhead connection is convertible to a flanged rotator.
