摘要： A method and apparatus for retrieving an assembly having a whipstock and an anchor from a wellbore. A method of retrieving an assembly having a whipstock coupled to an anchor from a wellbore may comprise the steps of releasing the whipstock from the anchor in the wellbore, re-engaging the whipstock to the anchor, and retrieving the whipstock with the anchor from the wellbore. An apparatus for use in a wellbore may comprise a whipstock, a latch coupled to the whipstock, and an anchor operable to be selectively retrieved from the wellbore using the latch.
