Abstract
A packer assembly is provided for use in a subterranean well and settable only by longitudinal manipulation of a tubular workstring. The assembly has an outer housing and a seal assembly with anchoring slips carried by the housing in retracted position and movable to expanded position along the wall of a casing or the like. A longitudinally extending central mandrel telescopes within the housing. Orienting and setting pins are provided for initial receipt within orienting and setting slots with the setting pins being moved to the orienting slot to permit setting of the packer. The seal assembly and anchoring slips are maintained in retracted position and are responsive to a variation in internal diameter between a first and second tubular conduit to thereafter permit the manipulating device to move the seal assembly and the anchoring slips to expanded position within only the second tubular conduit which has a diameter less than that of the first tubular conduit.
