Abstract

A tubing rotator and hanger connects to a wellhead having a wellhead flange. The rotator has a main body which includes a rotator flange mountable on a top side of the wellhead flange. A bore extends through the rotator body for inserting a mandrel therethrough. A load shoulder on a top end of the mandrel is supported by bearings on the rotator body. A removable split ring is located within an annular recess around the top end of the mandrel for connecting the mandrel to the load shoulder. A dognut is connected to a bottom end of the mandrel such that the dognut is disengaged from the wellhead during rotation of the tubing. A gear set within the rotator body rotates the mandrel in relation to the rotator body for rotating the tubing. A pair of pressure test ports connect an inner face of the rotator body to an outer face of the rotator body for monitoring pressure within the tubing rotator and hanger. A method is provided for removing the rotator body from the wellhead. The method includes connecting a pick up sub to an upper end of the mandrel for raising the mandrel such that the split ring may be removed. The mandrel is then lowered such that the dognut is seated within the wellhead. The pick up sub is then disconnected so the rotator body may be lifted from the wellhead.
