Abstract
A retrievable compression set packer is sequentially released. First the sealing element is allowed to relax. Then the upper slip has wedging action that forces it against a surrounding tubular relaxed. After that the upper slips are pulled up to retract them fully allowing the packer to come out. These sequential actions are done with a mandrel movement in one direction. The sealing element is released with undermining a collet by aligning collet heads with a recess on the mandrel. The slip force release happens with mandrel movement forcing a ring into a wedge such that circumferential force on slip segments is reduced or eliminated when the wedge is pushed out of its conforming slot allowing for circumferential flexibility of the slip seat. The mandrel then picks up a slip ring that retracts the slip segments on the slip seat and the packer is removed.
