A releasable no-go tool and associated methods provide enhanced capabilities in positioning an item of equipment in a wellbore. In a described embodiment, a releasable no-go tool includes a circumferentially continuous key which is radially outwardly displaced by a series of pistons. In use, the tool is interconnected in a tubing string, which is lowered into a casing string in a wellbore. The casing string has a nipple interconnected therein, the nipple having an internal profile. The tool is positioned below the nipple, pressure is applied to the tubing string to extend the key, and the tubing string is raised to thereby engage the key with the profile.
