Abstract: A method of providing for a single trip removal of packer tools by providing a flapper valve in the upper packer tools which opens when pressure below the tool exceeds the pressure above the tool to allow the tools to be released and allowing flow up the center of the tubing. Additionally, the retrieval tool seals with the stinger tool during removal to allow flow downwardly around the released packer down to the next lower packer and up through the released packer to work only on the next lower packer. The method also contemplates that increased flow circulation will allow forced flow to clear the next lower stinger from sand and other debris to increase the chance of a successful mating of the retrieval tool to the stinger during removal.

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.
