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.

The ,flowback, rate is dictated by the necessity to keep the fractures open. When proppant is used, the ,fluid flowback, rate must be slow enough to prevent viscous ,fluid, forces from pulling proppant out of the fractures. Thus, both conventional and unconventional HF ,flowback, operations occur at similar rates.
