ABSTRACT:
An oil field tool for setting a Wellbore Deviation Apparatus, for deviating a wellbore, which uses an improved whipstock incorporating an elongated setting slot in the face of the whipstock, attached to a hydraulic or mechanical anchor packer is disclosed. The tool permits full drill string weight to be applied to the whipstock while the whipstock is placed in the wellbore. Additionally, the setting tool allows torque to be applied to the whipstock without prematurely releasing the deviation assembly. The same tool is used with mechanical or hydraulic packers.
