Up-to-set lock mandrel and method of operation thereof

摘要

An up-to-set lock mandrel (10) for registering with a locating profile (14) recessed in a sidewall (16) of a well conduit portion (12). The up-to-set lock mandrel (10) comprises a generally cylindrical body (20) and a locating key (22) coupled to the body (20) and biased to be urged from a seeking position toward a no-go position. The locating key (22) has a no-go profile (26) thereon contoured to engage the locating profile (14) when the locating key (22) is in the no-go position, to thereby function as a no-go for the up-to-set lock mandrel (10). <IMAGE>
