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.

16/2/2017, · Thus, hydraulic fracturing is used to, facilitate entry into the well, or, to improve the gas/oil flow by reopening, the pores to bring it to the surface at, higher rates,. Therefore, the rock is fractured by high pressure or rather fluids are pumped into the well at pressures sufficient to create cracks in the formation using different types of technologies and fluids.
