description A running/setting tool for packers is disclosed which can release in several different ways. The tool can be pumped through for normal release. The tool may be hydraulically released by dropping and pumping a ball to a seat and subsequent pressurizing. A frangible member is provided so that if circulation is impeded, it can be established by breaking the frangible member to allow a ball to be pumped to a seat. Finally, a shear release technique is provided which allows release by breaking a shear pin or shear ring or other frangible member, which unsupports collets to allow for removal. A support shoulder is provided on the tool to prevent the collets from becoming stressed on the trip out of the hole if the tool encounters a collar or other internal obstruction.
