Embodiment Construction
[0017] Referring more particularly to the drawings, FIG. 1 illustrates a cross-sectional, plan view of wellbore 10 which has been drilled from the surface (not shown) through an unconsolidated production formation 11. As will be understood by those skilled in the art, wellbore 10 has been cased and cemented with casing 12 and cement 13 through formation 11. In carrying out the method of the present invention, openings 14 are formed through casing 12 and cement 13 at point(s) adjacent formation 11 to thereby provide fluid communication between the formation and wellbore 10. Openings 14 comprise two set of openings which are formed diametrically-opposed from each other in casing 13 and are positioned to lie substantially on the natural fracture plane of the formation.
[0018] Preferably, these openings are perforations which are formed by a standard 180.degree. perforating gun which, in turn, has been oriented with respect to the fracture planes of formation 11 by commercially-available...
