Multi-perf fracturing process

A method of fracturing a subterranean formation having a deviated well bore penetrating the formation, the method comprising the steps of:

• drilling a substantially vertical well bore into the formation;
• drilling a deviated well bore from the substantially vertical well bore into the formation at an angle from the vertical;
• placing a casing in the deviated well bore;
• creating a plurality of spaced fracture initiation points over a perforation interval in the well bore by forming perforations of a predetermined number and size through the casing from a first to a last set of perforations, whereby a limited known flow rate of fracturing fluid will flow through each set of perforations at the initiation points upon the application of hydraulic pressure;
• simultaneously applying hydraulic pressure under a predetermined conditions to all of the sets of perforations at the fracture initiation points to thereby simultaneously form a plurality of spaced substantially parallel fractures in the formation;
• wherein each perforation interval is shot more than once with a standard perforating gun to thereby achieve a desired number of perforations while minimizing the distance between the first and last sets of perforations;
• wherein said subterranean formation contains hydrocarbons and said fracture initiation points are spaced to obtain maximum hydrocarbon recovery therefrom;
• wherein the application of hydraulic pressure to the formation comprises pumping a fracturing fluid into said formation at a rate and pressure sufficient to fracture said formation;
• and
• wherein the fracturing fluid is comprised of stages of acid separated by stages of water.
