Abstract
A through tubing retrievable whipstock and installation method is disclosed. In the preferred embodiment, a plurality of anchor links pivot at one end and have wickers on an opposed rounded end. The links are configured to deliver an optimum contact angle with respect to the longitudinal axis of the whipstock in a variety of casing sizes and weights. A lock ring system holds the set position and the upper end is hinged and biased to stay out of the way of the mill or mills and yet be easy to engage by a retrieving tool.
