Abstract
Techniques for correlating depth on a tubular in a wellbore include a casing collar locator tool that includes a tubular mandrel defining a bore therethrough; a top sub-assembly and a bottom sub-assembly carried on the tubular mandrel; a profile carried on the tubular mandrel axially between the top sub-assembly and bottom sub-assembly and adjustable between an engaged state defined by the profile extending radially away from the mandrel and a disengaged state defined by the profile refracted towards the mandrel; and a wedge sleeve carried on the tubular mandrel between the top sub-assembly and the bottom sub-assembly and arranged, at least in part, axially adjacent the profile, the wedge sleeve actuatable to urge the profile into at least one of the engaged state or the disengaged state.
