Abstract: A method of stimulating a formation containing two or more wellbores includes simultaneously stimulating a first region of each wellbore using a stimulation fluid so as to create a primary fracture in the first region of each wellbore, wherein the first region comprises a first opening or openings allowing fluid communication between each wellbore and the formation, wherein the first region has a first stimulated lateral length and wherein the flow rate of the stimulation fluid through the first opening or openings is greater than 1 barrel per minute per foot of the first stimulated lateral length.

Abstract: A reservoir stimulation tool for stimulating a formation surrounding a wellbore having an inner wall includes: a tubular string including an outer wall defining therein an inner bore, the tubular string being configured to be inserted into the wellbore so as to form an annular space between the tubular string and the inner wall of the wellbore, a plurality of ports formed in the outer wall of the tubular string; a plurality of port valves for opening or closing the ports; and a plurality of packers coupled to the tubular string, wherein each packer is configured to be expanded in order to engage the inner wall of the wellbore, thereby isolating two or more longitudinal segments of the annular space from each other.
