After ,fracturing, operation, hydraulic fractures and induced fractures are created within the shale reservoir. A lot of ,treatment, water is stored in fractures network and ,flow back, into the surface during the gas recovery process. The gas prodn. performance is affected by the water ,flowback, because two phase flow occurs within fractures zone.
