ABSTRACT:
An anchor for a wellbore is adaptable to be operated in at least two separate and distinct ways. In one embodiment, a whipstock anchor is provided that can be operated either mechanically or hydraulically. In another embodiment, the anchor is designed to run through a restriction in a retracted position and thereafter expanded to position a wellbore tool in the wellbore. Preferably, the anchor is expandable to set in wellbores of various sizes and either cased or uncased.
