ABSTRACT:
The present invention is to a pre-selected set of packer tools having J tools and on/off tools (“stingers” and “washovers”) with varying strokes and varying set and release directions to enable the operator to individually address the various packers. By increasing the amount of travel necessary to set and/or release the subsequent packer tools, it is possible to select which tool is being manipulated or operated upon.
