A method and apparatus for severing the mandrel of an anchor device such as a packer to release the packer and remove it from a well. A cutter locator profile above the packer assembly and a cutter locator element on the cutting tool are located so as to precisely position the cutting element at a desired location on the packer mandrel. Once the mandrel is severed, the packer assembly can elongate to release the expansion mechanism. Then, the packer assembly can be pulled upwardly to release the packer, and to remove it from the well. A cutting tool can be lowered through production tubing to sever the mandrel, followed by pulling the packer with the production tubing. Alternatively, a cutting tool can be lowered on a workstring and latched to the upper end of the packer assembly, followed by severing the mandrel and pulling the packer with the workstring.
