Abstract
A perforating gun assembly () for creating communication paths for fluid between a formation () and a cased wellbore () includes a housing, a detonator and a detonating cord (). The perforating gun assembly () includes one or more substantially axially oriented collections of shaped charges () each of which is operably associated with the detonating cord (). A perforation () is formed in the formation () as a result of the interaction of jets () formed upon the detonation of at least two shaped charges () that create a weakened region () in the formation () followed by the detonation of at least one shaped charge () that forms a jet () that penetrated through the weakened region ().
