ABSTRACT:
Retrievable window cutting apparatus and method include a whipstock assembly 160 and anchor assembly 10. Whipstock assembly 160 and anchor assembly 10 contract radially inwardly to pass through tubing string T and then expand radially outwardly to operate in casing C. Upper and lower independently moveable slips 24 and 26 engage casing C. Whipstock assembly 160 includes hinge assembly 170 that can be set for operation with a milling assembly 270. Cooperation between shear members in setting tool WSS, working string adaptor 180, hinge assembly 170, and anchor assembly 10 provide for keeping whipstock assembly 160 and anchor assembly 10 in a contracted position for passing downwardly through tubing T, expansion in casing C, and subsequent retrieval through tubing T.
