Abstract

A technique facilitates perforating along specific regions of a wellbore without creating detrimental transient pressure changes along a perforating gun string. In non-perforation regions, pressure charges may be used to maintain pressure within the gun string without creating perforations through the surrounding casing and into the surrounding formation. Each pressure charge may comprise a casing with an explosive material disposed in the casing. However, the components and structure of the pressure charge enable detonation and the corresponding increase in pressure within the gun string without creating perforations.
