Abstract
An example latch coupling assembly includes a latch coupling defining an inner latch profile and an expandable sleeve coupled to the latch coupling. A latch defining an outer latch profile is mateable with the inner latch profile, and a mandrel is at least partially extendable within the expandable sleeve. An expansion cone is moveable along the mandrel between a first position, where the expansion cone is positioned within the expandable sleeve, and a second position, where the expansion cone is moved into engagement with an inner radial surface of the expandable sleeve to radially expand the expandable sleeve into engagement with a casing string and thereby secure the latch coupling within the casing string.
