ABSTRACT:
A stinger assembly for use in releasably connecting an upper section of a tubing string to a tool in a well includes a mandrel with a master cam slot formed therein to define upper and lower support shoulders. An indexable collar telescoped on the mandrel includes a follower which fits within the slot so that as the mandrel is moved vertically, the follower rides within the slot indexing the collar between upper and lower positions relative to the mandrel. A collet is journaled on and carried by the collar and includes a plurality of radially flexible spring-fingers which in the lower position are blocked against deflecting radially inwardly and in the upper position are free to deflect inwardly into an annular recess on the mandrel. The upper shoulder in the master cam slot supports the follower so that the spring-fingers are in registry with the recess to allow the collet to be disconnected from the well tool.
