Do I need to isolate each zone I wish to stimulate with the GasGun?
For the same reason as described above there is no need to isolate each zone you wish to stimulate with GasGun through the use of packers or bridge plugs. If a GasGun tool is placed at a different location from the first, the fluid tamp between the zones will force the energy to be expended on the formation immediately adjacent to the tool. Fracturing is restricted to within a few feet vertically of where the tool is placed (see energy loss calculations).
