Abstract

An apparatus for determining a location of an inner string in an outer string includes an axis parallel to a longitudinal axis of the inner string, and a tagging assembly disposed at a tagging location in the outer string, the outer string configured to be deployed into a borehole in a subterranean region, the inner string configured to be advanced through the outer string. The tagging assembly includes a stop component configured to obstruct axial movement of the inner string through the outer string at the tagging location, the stop component configured to be displaced in response to an axial force applied to the stop component by the inner string, to permit the inner string to advance axially beyond the tagging assembly.
