Abstract:
A pack-off tubing hanger is shown for use in a tubing string extending from a well surface location to a downhole location within a well casing. The hanger body includes an external packing element and gripping slips which support the hanger body within the surrounding casing. A longitudinal passageway communicates hydraulic pressure from the lower end of the hanger to a setting chamber to hydraulically set the packing elements and actuate the gripping slips. A companion concentric tubing anchor is carried within the internal bore of the hanger and connects the hanger to the tubing string leading to the well surface.
