ABSTRACT:
A retriever tool includes a central mandrel with a collet sleeve slidably disposed about the mandrel. The collet sleeve includes a plurality of upwardly extending spring fingers, each of the spring fingers having an upper portion including an upward facing catcher shoulder for catching a bridge plug or similar device to be retrieved from a well. Located above the catcher shoulder of the upper portion of the spring finger is an arcuate substantially constant diameter outer surface. Located above the arcuate substantially constant diameter outer surface is an upward facing tapered outer guide surface for guiding the constant diameter outer surface from below into engagement with an inner surface of the bridge plug to be retrieved. Provision is made for releasing the retriever tool from the bridge plug in the event that the bridge plug becomes hung up in the well.
