Abstract:
1. A method for stimulating one or more hydrocarbon-containing intervals of interest in a subterranean formation for producing oil and gas through a wellbore, comprising: running a completion string into the wellbore, the completion string having a wall for forming an exterior annulus between the wall and the formation, a bore and one or more stimulation locations spaced therealong, each stimulation location comprising isolating the exterior annulus at a selected interval of the one or more intervals of interest; running a treatment tool into the completion string and forming a treatment annulus therebetween, the treatment tool having uphole and downhole isolation devices for sealing in the treatment annulus and a treatment port therebetween; positioning the treatment tool adjacent a selected stimulation location of the one or more stimulation locations corresponding to the selected interval, the uphole and downhole isolation devices sealing the treatment annulus thereabout; flowing fluid through the bore of the treatment tool to flow into the treatment port to the isolated treatment annulus for increasing a fluid pressure therein to a threshold pressure for rupturing all of the burst disks in the at least one set of burst disk assemblies at the selected stimulation location for displacing the caps therefrom for fluidly connecting the bore with the treatment annulus and initiating detonation of the shaped charges for forming perforations in the formation at the selected interval.
