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.
