Abstract: A ball lift sleeve and retrieval tool comprising a sleeve for disposing in tubing of a well, the sleeve defining a first passage from a first proximal end to a first distal end, and a retrieval tool for disposing in the tubing of the well, the retrieval tool being separately moveable in the tubing between mated and unmated conditions with respect to the sleeve, the retrieval tool at least partially mating with the first distal end of the sleeve when in the mated condition and at least partially closing fluid communication through the passage of the sleeve when mated therewith.
