Abstract
Method and apparatus are presented for perforating a subterranean formation so as to establish fluid communication between the formation and a wellbore by perforating a tubular with a mechanical perforator. The mechanical perforator comprises a perforator housing, a mandrel slidably positioned within the perforator housing, and at least one penetrator outwardly extendable from the perforator housing. When shifted axially the mandrel causes at least a portion of the at least one penetrator to extend outwardly from the perforator housing to perforate the tubular.
