Abstract: Releasing slips for use with a downhole tool, a tool for deploying downhole in a well utilizing the releasing slips and a well in which a downhole tool is deployed utilizing the releasing slips of the invention is described herein. The tool has a plurality of slips for selective engagement with a wall of a wellbore. The slips include releasing slips and biting slips. The releasing slips have a low friction surface, e.g., a substantially smooth surface for engaging the wall of the wellbore. The smooth wall engaging face of the releasing slips facilitate easy release of the slips, thereby facilitating easy removal of the downhole tool. The slips may include a plurality of hardened members that protrude from the wall engaging face of the releasing slips to reduce wear on the face of the releasing slip.

Abstract: A retrievable seal bore packer adapted to be lowered into a casing on a wireline and set by a wireline gun. The packer is retrieved by a retrieving tool lowered into the casing on a wireline by a downward force followed by an upward force on the wireline. The packer has a cylindrical mandrel, selectively engageable slips, a lower cylindrical element encircling the mandrel and bearing against the bottom of the slip and an upper cylindrical element encircling the mandrel and bearing against the top of the slip. The wireline gun is interconnected with the cylindrical mandrel and the upper cylindrical element to selectively cause relative movement therebetween and to thereby engage the slips with the casing.
