Abstract
One or more burst disks, for isolating downhole communication between a tubular and a hydrocarbon-bearing formation, are fit with a shaped explosive charge. Detonation of the shaped charge is initiated by the rupture of the burst disk. In a system for stimulating the formation, one or more sets of two or more shaped charge, enhanced burst disks are located at a location along the tubular corresponding to a selected interval for stimulation. The enhanced burst disks can be fit with a chamber of known pressure for establishing a known and significant pressure differential across the burst disk for enabling substantially simultaneous rupture at the selected interval.
