This mixture, called fracturing fluid, creates fissures in the shale increasing its permeability and gas recovery. The mixture of the injected fracturing fluid together with the connate water of the formation, which returns to the surface within few weeks after pressure being released, is called flowback water (Olmstead et al., 2013).
