Methods for stimulating a subterranean formation comprising providing a stimulating fluid stream to a casing conduit that is defined by a production casing that extends within the subterranean formation to increase a fluid pressure within the casing conduit. The methods further include locating an isolation device on an isolation sleeve to fluidly isolate a downhole portion of the casing conduit from an uphole portion of the casing conduit and opening an injection port that is associated with the isolation sleeve to permit an injection port fluid flow into the subterranean formation. The methods also include sealing the injection port and creating an uphole perforation in the uphole longitudinal section of the production casing responsive to the fluid pressure exceeding the threshold perforating pressure.
