A method for setting an oil field Wellbore Deviation Apparatus, for deviating a wellbore, which uses an improved whipstock incorporating a slotted face, attached to a hydraulic or mechanical anchor packer is disclosed. The method permits the proper "set" of a mechanical packer without fear of shearing the releasable attachment device currently used in the industry and permits an operator to "bottom hole wash" while setting a mechanical packer in a wellbore. The same method, with slight modifications, is used for both mechanical or hydraulic packers.
