  • Publication number: 20220307808
    Abstract: A detonating cord for using in a perforating gun includes an explosive layer and an electrically conductive layer extending around the explosive layer. The electrically conductive layer is configured to relay a communication signal along a length of the detonating cord. In an embodiment, a protective jacket extends around the electrically conductive layer of the detonating cord. The detonating cord may be assembled in a perforating gun to relay a communication signal from a top connector to a bottom connector of the perforating gun, and to propagate a detonating explosive stimulus along its length to initiate shaped charges of the perforating gun. A plurality of perforating guns, including the detonating cord, may be connected in series, with the detonating cord of a first perforating gun in communication with the detonating cord of a second perforating gun.
