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.
Claims19
A rectilinear setting tool for use with a slotted face wellbore deviation assembly which includes
- a whipstock, adapted for securing to an anchor packer, having a back side, a tool face, a top, a bottom, and a longitudinal central axis;
- and having
- an elongate setting slot having a rear wall, a front side, an apex and a base, extending into the whipstock from said tool face thereof and extending from near said top of the whipstock toward said bottom thereof such that the front side of the elongate setting slot is an opening within the tool face of the whipstock;
- comprising:
- a bar having a top end, a bottom end, a back side, a front side and side walls, with said bar configured and dimensioned to be slidingly received and releasably secured within the elongate setting slot.
