For shale wells, hydraulic ,fracturing, is essential and applied extensively, requiring ,large, quantities of frac ,fluid, [approximately 11.5–19 ML per well, ML= million liters; U.S. DOE, 2009]. Typically, 10–70% of frac ,fluid, returns to the surface during the initial period of production (<4 weeks from onset of gas production) [ American Petroleum Institute ( API ), 2010 ], referred to as “,flowback,.”

One reason why ,recycling, is minor to negligible is that ,flowback, volumes are far from providing enough water for a subsequent HF operation, especially at early times. The median well produces ~25% of the injected volume after 6 months and ~40% and plateauing after 1 year. ,Flowback, / produced water is actually disposed of in injection wells.
