ABSTRACT:
An oil field retrieval tool for retrieving a specially designed and retrievable slotted face wellbore deviation apparatus incorporating a special whipstock attached to a hydraulic or mechanical anchor packer is disclosed. The apparatus utilizes a slot cut in the face of the whipstock portion of the deviation apparatus for guiding the retrieval tool into place within a retrieving slot set in the face of the whipstock. In addition, the retrieval tool uses drilling fluid to wash the retrieval slot and guide slot clear of cuttings and has an engagement signaling means.
