RETRIEVABLE PACKER WITH PUSH ROD RELEASE

The retrievable packer system includes a packer mandrel, a lock ring, an upper cone, a lower cone, a slip device, a retrieval mandrel, and a plurality of push rods. The lock ring is attached to the packer mandrel, followed by the upper cone, the slip device, the lower cone, and the retrieval mandrel. The lower cone has lower cone rod channels, and the push rods anchored on the retrieval mandrel slide through respective channels toward the upper cone. The packer system is run into the borehole with each rod in the first position relative to a tip end of the lower cone and the slip device in the run-in position. The packer system is set and can be locked at a location in the borehole. Each push rod can push the upper cone to return the slip device to the run-in position for retrieval of the packer system.
