Wellbore lock system and method of use

摘要

A lock assembly includes radially movable engagement or latch members configured to engage a profile within a subsurface nipple, and further includes one or more sealing assemblies. The sealing assemblies are radially expandable by enlarging the interior of diameter of the elements of the sealing assembly, such as by placing a mandrel of relatively enlarged diameter through an internal diameter of elements of the sealing assembly.
