ABSTRACT:
An improved method for fracturing oil wells is disclosed and claimed herein. In particular, the present invention involves the determination of the direction of fracture propagation, i.e., perpendicular to the minimum stress existing within a given formation and the alignment of perforations produced by a variety of perforating devices with the previously determined direction of fracture propagation. The methods disclosed and claimed herein will eliminate many problems encountered in the prior art, including reducing the pressure required to initiate fractures and reducing the undesirable effects of near wellbore tortuosity. A solidified compound may be placed proximate the fractures to further limit undesirable sand production.
