ABSTRACT:
A perforating gun assembly (60) for creating communication paths for fluid between a formation (64) and a cased wellbore (66) includes a housing (84), a detonator (86) positioned within the housing (84) and a detonating cord (90) operably associated with the detonator (86). The perforating gun assembly (60) also includes one or more substantially axially oriented collections (92, 94, 96, 98) of shaped charges. Each of the shaped charges in the collections (92, 94, 96, 98) is operably associated with the detonating cord (90). In addition, adjacent shaped charges in each collection (92, 94, 96, 98) of shaped charges are oriented to converge toward one another such that upon detonation, the shaped charges in each collection (92, 94, 96, 98) form jets that interact with one another to create perforation cavities in the formation (64).
