  • Casing conveyed perforating process and apparatus
    Patent number: 6761219
    Abstract: A process and apparatus for completing a subterranean well bore in at least one subterranean formation. At least one perforating gun assembly is positioned on the outside of casing in a subterranean well bore. A suitable signal, such as a hydraulic, electric or wave signal, is transported to the perforating gun assembly so as to detonate one or more explosive charges in the perforating gun assembly which are aimed toward the casing. At least one wall in the casing is perforated thereby establishing fluid communication through the wall of the casing. Usually, cement surrounding the casing and a subterranean formation surrounding the casing are also perforated to establish fluid communication between the formation and the interior of the casing.
