My formation is really close to water. Will the GasGun fractures have vertical growth that could “bring in the ocean”?
Based on research conducted by Sandia National Laboratories, fractures are expected to grow radially from 10 to 50 feet out into the formation, but no more than 2 to 5 feet above or below the zone treated. GasGun stimulations are not like hydraulic fracturing which is conducted so slowly that the treatment has time to find the path of least resistance. The time of pressurization for the GasGun is only tens of milliseconds and the pressures reached overpower the earth’s internal stresses. This forces the fracturing to be confined to within a few feet vertically of the zone in question. However, unique downhole conditions make it impossible to make any absolute guarantees.
