This idea is well followed when it comes to the hydraulic, fracturing, of a, shale gas, well. Therefore, numerous studies have focused on increasing the, flowback, rate of HFF in, shale gas, reservoirs to mitigate the water blocking damage. Yet, only a small portion of the injected, fluid, (less than 20%) could be recovered during, flowback, operation.
