Abstract: A tool, known as FM/WL Tool, utilized with a wireline adaptor kit would be secured to the lower end of a wireline setting tool.  The adaptor kit would release from the tool when sufficient setting force is applied, and is retrieved with the wireline setting tool.  The wireline setting tool provides for a telescoping action and sufficient force in order to push the outer parts down from the top as the inner mandrel of the tool and the stinger, top sub and bottom  sub  are  pulled  upward.    The  upward  pull  is transferred to a sleeve by a plurality of lugs on bottom sub assembly.  This action causes the packer tool to set by compressing rubber elements   and holding the  elements compressed by a first upper set of slips and a second lower set of slips wedged between the casing and the upper cone and the lower cone.  During the setting action, the pickup sleeve and parts attached will move down until the top slips are wedged against the top cone.  The spring, which would be fully open when the tool is lowered downhole, will be compressed until the pickup sleeve adaptor shoulders against  spring  cap.    A  lock  ring  holds  the  spring compressed.  Bottom sub assembly includes a threaded nut having lugs protruding into the straight slots and sleeve. The lugs transfer the upward setting force from the mandrel to the sleeve and prevent upward movement of the inner mandrel after the packer is set.   The threaded nut is attached to the bottom sub assembly with a  left hand thread.  Multiple right hand rotations of the inner mandrel and bottom sub assembly will release the threaded nut and allow the inner mandrel to move upward.  This right hand rotation and upward movement of the inner mandrel is the action required for releasing the packer in order to allow it to be retrieved from the hole.     Upper movement of the inner mandrel brings a small outside surface under the seal creating a passage that allows the pressure to equalize.  This upward movement also raises  the  lock ring releasing the  spring compression against the top slips and causes a shoulder on the top sub to contact a shoulder on the pickup sleeve.   Pulling against  the  shoulder  will  pull  the  top  slips  loose, releasing  the  packer.    Continued  upward movement,  of course, would completely retrieve the FM/WL packer from the hole.
