Perforating gun assembly and method for creating perforation cavities

A perforating gun assembly comprising:

• a housing;
• a detonator positioned within the housing;
• a detonating cord operably associated with the detonator;
• and
• a plurality of shaped charges forming a substantially axially oriented collection, the shaped charges operably associated with the detonating cord, adjacent shaped charges in the collection oriented to converge toward one another.

• a detonating cord operably associated with the detonator;
• and
• a plurality of shaped charges forming a substantially axially oriented collection, the shaped charges operably associated with the detonating cord, adjacent shaped charges in the collection oriented to converge toward one another such that upon detonation, the shaped charges in the collection form jets that interact with one another to create a perforation cavity in the formation.

A perforating gun assembly comprising:

• a housing;
• a detonator positioned within the housing;
• a detonating cord operably associated with the detonator;
• and
• a plurality of collections of substantially axially oriented shaped charges, each collection of shaped charges in the plurality of collections of shaped charges being circumferentially phased relative to adjacent collections of shaped charges.

A completion comprising:

• a subterranean formation;
• a wellbore that traverses the formation;
• and
• a casing disposed within the wellbore, wherein the formation has a perforation cavity formed therein as a result of an interaction of jets created upon the detonation of a collection of shaped charges within the wellbore.
