Abstract
A method comprises providing a gun string assembly within a wellbore and perforating the wellbore using the gun string assembly. The gun string assembly comprises a plurality of perforating guns coupled in series. A first perforating gun of the plurality of perforating guns comprises a first portion of shaped charges, and a second perforating gun of the plurality of perforating guns comprises a second portion of shaped charges operably associated with a secondary pressure generator. The first perforating gun and the second perforating gun are configured in the gun string assembly to provide a pressure transient comprising one or more pressures at a location in the wellbore that meet one or more thresholds.
