Abstract: A method is provided which releases and retrieves an opposed slip downhole tool by reducing the compressive forces on the sealing elements prior to unsetting the slip assemblies. Further, the method does so without damaging the slip assemblies. The method provides for the retrieval of the entire downhole tool including all of its component parts, requiring but a single trip within the wellbore. When the tool is to be retrieved, the sealing element is disengaged from the casing by relaxing the compression forces on the sealing element. Then the slip assemblies are disengaged from the casing such that the slip assemblies are no longer in gripping engagement with the casing. The tool is then retrieved from the wellbore. The step of disengaging the sealing assembly can be performed by radially contracting the sealing element with or without longitudinally expanding the sealing element.

Abstract: A slip for use in the anchoring device on a well tool has a wedge shaped body and teeth on the exterior of the body. The teeth are formed from a ring segment of spring steel material mounted on and extending from the exterior of the body. The ring segment may be mounted in a circumferential groove on the body.

Abstract: An apparatus and method for installing and removing packer assemblies from a subterranean well. A packer assembly has a stop that prevents the seal assembly from relaxing. The stop is cut axially by use of a chemically reactive cutter device lowered into the well and activated by use of conventional wire line equipment. Once cut, the seal assembly on the packer is allowed to relax and can be removed intact from the well.
