High amounts of ,fluid, wastes (,flowback, waters) are a result of hydraulic ,fracturing,. After cracking a well, the ,fluid, is removed from the drillbore as well as from the cracks and gaps in the surrounding rock. As has been proved in American research, the amount of the ,fluid, obtained in shale gas ,fracturing, is lower than in the case of

Abstract. Chemical additives used in hydraulic ,fracturing, (HF) for unconventional natural gas production can be a ,risk, to environmental and human health (EHH). The EHH ,risk, is affected by three factors: the chemical hazard measured, the certainty of the measured hazard, and the use frequencies of additives.

Fracturing fluid migration is a multiphase flow problem in which gas or oil (the nonwetting phase) contained in the shale interacts with HF fluid or brine (the wetting phase). Most shale gas plays have low brine saturation (0.1–0.5), which gives rise to a number of multiphase flow effects such as capillary imbibition and reduced relative permeability [ Byrnes , 2011 ; Engelder , 2012 ].

One of the major concerns related to UOG extraction is the risk of accidental releases during wastewater management. UOG extraction uses technologies of horizontal drilling and hydraulic fracturing. Flowback and produced water are generated as wastewater and may contain high concentrations of salts, metals, oil, grease, and organic compounds.
