Claim 17:
18. A system for completing a wellbore extending through a subterranean earthen formation, the system comprising:
a casing string positioned in a wellbore extending through a subterranean earthen formation;
a first perforating assembly coupled to the casing string, wherein the first perforating assembly comprises:
a first perforation charge coupled to the casing string, wherein the perforation charge comprises an explosive material configured to blast towards the earthen formation upon detonation of the first perforation charge; and
a first seating device coupled to the casing string, wherein the first sealing device comprises an open configuration configured to permit fluid flow across the first sealing device and a closed configuration configured to restrict fluid flow across the first sealing device when in the closed configuration;

a second perforating assembly coupled to the casing string, wherein the second perforating assembly comprises:
a second perforation charge coupled to the casing string, wherein the second perforation charge comprises an explosive material configured to blast towards the earthen formation upon detonation of the second perforation charge; and
a second sealing device coupled to the casing string, wherein the second sealing device comprises an open configuration configured to permit fluid flow across the second sealing device and a closed configuration configured to restrict fluid flow across the second sealing device when in the closed configuration;

a surface pump in fluid communication with the central passage of the string assembly, the surface pump configured to elevate a hydraulic pressure in the central passage and to maintain the elevated hydraulic pressure in the central passage between an actuation of the first sealing device from the open configuration to the closed configuration and the actuation of the actuation of the second sealing device from the open configuration to the closed configuration.
