ABSTRACT:
A hydraulically operated assembly that may be removably secured to the well head of an oil well to concurrently raise a tubing hanger that has a tubing string supported in either a centered or offset position therefrom to an elevation where replacements or repairs may be made to electrical components including the lower electrical connector. The tubing string upon being lifted is moved to a centered position in the blow out preventer to permit the latter to be closed to gain control of the well if necessary. The assembly eliminates the necessity of moving a rig over the well to service the electrical components therein.
