A shock tube package system and a method of deploying a shock tube package system is provided. The system includes a covering made from a flexible or elastic material, the covering defining an interior portion. A bundle of shock tubing is disposed within the interior portion, the covering applying a compression fit on the bundle of shock tubing. The bundle of shock tubing having a first end and a second end, the first end being configured to couple with an initiator device, the second end being configured to couple with a detonator.

A method comprising the steps of providing an Explosive Initiation Safety and Handling System (EISS) coupled to a robot, operatively coupling a charge carrier table and a manipulator to the robot; securing a charge to the charge carrier table; installing a shock tube spool on the shock tube spooling mechanism and locking with an indexing nut; inserting the shock tube that has been uncoiled from the spooling mechanism into the interrupter and replacing the cap; attaching the shock tube to the charge; making an initiator-to-interrupter connection with the shock tube; retracting the manipulator on the robot to a fully stowed position and rotating the charge carrier in front of the robot; picking up the charge with the manipulator, extending the manipulator forward and placing the charge at a threat; stowing the charge carrier; positioning the robot at a distance from the threat, allowing the shock tube to spool out; remotely activating a first firing circuit on the robot to arm the system; cutting the shock tube inside the interrupter and aligning the shock tube with the initiator; and firing a second circuit to initiate the shock tube.

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.

A wireless electronic initiation device for a detonator via a shock tube comprises an initiation member for initiation the shock tube and an energy storage for providing initiation energy to said initiation member. The initiation device comprises also a wireless communication device with a receiver for receiving an initiation command in a wireless way from an initiation arrangement. The initiation device comprises also a controller, which is configured to determine said received initiation command and based on said received initiation command configured to activate said initiation member to ignite the detonator initiator (108) by the energy fed from the energy storage.
