Abstract: The present invention, in certain embodiments, discloses a whipstock system which is hydraulically settable in a tubular or wellbore and mechanically retrievable. In one aspect it is a "through-tubing" system. In certain aspects systems according to this invention have a concave to a lower end of which is secured an anchor housing bendable member, movable connection, or with an anchor body therein that is in fluid communication, via a flexible hose within the anchor housing, with a fluid channel running through the concave. An upper end of a mandrel is housed in a recess in the anchor body. The mandrel's lower end may extend out from the anchor housing. A setting slip is disposed below the anchor body within an opening in the anchor housing. A pusher sleeve below the slip is selectively displaced up by a piston below the pusher sleeve to push the slip out from the opening in the anchor housing to set against an interior of a tubular or of a wellbore. Fluid under pressure flows, e.g.
