Abstract
A pre-milled window casing on a casing string for allowing a cutting tool inserted into said will to contact the earth through said hole provided in said casing. Portions of a casing section along a casing string have been removed to allow drilling outwardly from the casing string at desired depths along the well. Orientation tools are provided to properly orient the window in the direction of drilling. A whip stock with an orientation nipple is inserted and mated with an orientation slot contained in an orientation sub portion of the casing string to align the whipstock with the window. A drilling tool inserted through the casing is redirected by an upper slanted face of the whipstock through the window where a hole can be bored through the earth to a gas deposit.
