High salinity concns. were used as indicator for estg. the percentage of hydraulic ,fracturing fluid, and formation water in ,flowback,. For the studied shale gas well a proportion of formation water, 69 %, and hydraulic ,fracturing fluid,, 31 %, in ,flowback, were derived. Thus, 92 % of the hydraulic ,fracturing fluid, remained in the formation.

Control (UIC) wells. Due to the lack of such wells in Pennsylvania, ,flowback, and produced waters are generally reused for hydraulic ,fracturing,. Because only 10-40% of the hydraulic ,fracturing fluid, returns to the surface during the ,flowback, period, it is necessary to supplement this impaired water to be able to fracture the nextwell.

During oil and natural ,gas production,, so-called “produced water” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic ,fracturing, (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.

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).
