Abstract:
A tubing hanger assembly including an outer hanger body (8) lands on a load shoulder (10) of a tubing head. Additionally, an inner hanger body (9) having at least one inner hanger groove (19) moves vertically up and down with respect to the outer hanger body and engages at least one downhole device. A first latch ring (11) expands into a groove (12) of the tubing head to lock the outer hanger body in position and a sleeve (14) with a plurality of grooves (20) is disposed between the outer hanger body and the inner hanger body of the tubing hanger assembly. Furthermore, a second latch ring (15), disposed between the sleeve and the inner hanger body, expands into or collapse out of the at least one inner hanger groove (19) and the plurality of grooves (20) on the sleeve (14), and the second latch ring (15) is a tension loading support for the inner hanger body.
