Claim 12:
13. A method for completing a wellbore extending through a subterranean earthen formation, the method comprising:
(a) actuating a first sealing device located in a string assembly positioned in the wellbore from an open configuration to a closed configuration whereby fluid flow across the first sealing device and further downhole through the string assembly is restricted;
(b) detonating a first perforation charge uphole from the first sealing device to provide fluid communication between a central passage of the string assembly and the earthen formation through a first opening in the string assembly formed by the detonated first perforation charge;
(c) elevating a hydraulic pressure within the central passage of the string assembly to communicate a fracturing fluid through the first opening and hydraulically fracturing the earthen formation;
(d) actuating a second sealing device located in the string assembly uphole from the first dealing device and the first opening from an open configuration to a closed configuration whereby fluid flow across the second sealing device and further downhole through the string assembly is restricted; and
(e) detonating a second perforation charge uphole from the second sealing device to provide fluid communication between the central passage of the string assembly and the earthen formation through a second opening in the string assembly formed by the detonated second perforation charge; and
(f) maintaining the elevation of the hydraulic pressure within the central passage of the string assembly through steps (a) through (e) whereby the fracturing fluid is communicated through the second opening to hydraulically fracture the earthen formation.
