Abstract
Apparatus and method of positioning and seating a retrievable insert landing assembly within a packer bore receptacle in a well bore. Means are provided for releasably securing a landing assembly in the packer bore receptacle by engaging an annular groove in the PBR with latching elements on the landing assembly. The latching elements are normally in a retracted position and are actuated by hydraulic pressure. The landing assembly has an internal polished bore which slidably and sealingly receives a tubular extension attached to a releasable coupling. The releasable coupling is disconnectable from the landing assembly after it is latched in place. To retrieve the landing assembly a spear mechanism is run in the tubing and an upward pull shears a release mechanism in the landing assembly. The retrievable landing assembly is hydraulically set and mechanically retrieved.
