The present invention provides a tool capable of being set and released. A novel arrangement of a push sleeve in the spring body eliminates several shear pins while an internal J slot formed directly on the mandrel significantly reduces the size of the lower drag body and thus the length of the tool. An internal pathway between the inner mandrel and the mandrel body selectively provide increase flow through the packer tool to facilitate running in of the tool.

Patriot retrievable production packer

In order to prevent premature separation of the slip and slip spring and to simplify production of the slip casing, a self-centering spring engageable with a packer tool slip is modified according to the present invention. A groove located at a lower center of the slip below the pocket of the slip cooperates with the spring to retain the spring against the slip and is centered within the pocket without requiring partitions or further welding of lugs to retain the springs.
