Abstract
A packer setting tool is disclosed for providing quick and reliable release thereof from a well casing packer. The setting tool is adapted for lowering the packer assembly within the casing. The setting tool is rotated by a drill string to release an upper set of packer assembly slips into engagement with the well casing. The packer setting tool is then lifted, thereby deploying a rubber sealing boot and setting the upper and a lower set of slips into permanent engagement with the casing. The packer setting tool is then again rotated, whereupon a shear connection is released and the setting tool can be removed from the packer and out of the well bore.
