Abstract of the Disclosure An improved method of forming a plurality of spaced sub- stantially parallel fractures in a subterranean formation from a deviated well bore penetrating the formation is pro- vided. The method comprises drilling a substantially ver- tical well bore into the formation and forming an initial fracture therein by applying hydraulic pressure to the for- mation. The in situ least principal stress direction in the formation is determined from the initial fracture and a deviated well bore is then drilled from the substantially vertical well bore into the formation at an angle and in a direction substantially parallel to the in situ least prin- cipal stress direction in the formation. Casing is placed in the deviated well bore, and a plurality of spaced frac- ture initiation points are created therein by forming a set of perforations of predetermined number and size through the casing and into the formation at the location of each of the fracture initiation points. Hydraulic pressure is applied under predetermined conditions to the sets of perforations at the fracture initiation points simultaneously to thereby extend a plurality of spaced substantially parallel frac- tures in the formation from the deviated well bore.
