ABSTRACT:
A thru-tubing retrievable whipstock is disclosed. A running tool creates relative movement to pivot out anchors at the lower end of the whipstock to accomplish its support. The setting force is trapped by spring-loaded wedges. The whipstock can be released and retrieved through tubing by undermining the wedges which allows retrieval of the whipstock by a pick-up force on the whipstock which collapses the anchoring mechanism for retrieval of the entire assembly to the surface.
