Abstract
A packer apparatus for use in a subterranean well comprises an inner mandrel and means for applying tension to the inner mandrel to set radially expandable slips and packing elements. The mandrel can be releasably positioned in a first position to secure the slips and packing element in the retracted position and can be shifted to a second position in which engagable lock segments secure the slips and packing element in expanded configuration. The packer can be released by rotational manipulation or by axial force. The packer apparatus can be used with rotationally manipulatable well tools positioned either above or below the packer apparatus.
