US Patent 10502036 Perforating gun system

A system and methodology are provided for improving the triggering (firing) of perforating guns, such as perforating guns deployed downhole via tubing. According to an embodiment, a methodology is provided for dependably communicating with an electronic firing head. The electronic firing head receives signals via wireless telemetry, such as either electromagnetic or acoustical telemetry. The methodology prevents surface or off depth detonation of the perforating guns by utilizing a fire command protocol.
