Three years ago Stewart says he started testing produced water and fracture ,flowback, fluids from oil and gas operations in an effort to purify them for reuse. “Whether it is treating contaminated water in developing countries, wastewater, or frac ,fluid, that has flowed back to the surface, our standard for treated water is to make it potable,” Stewart insists.

The fracturing wastewater (FWW) comes mainly from the fracturing fluid that flows back to the surface from the wellbore during the fracturing process (Shih et al. 2015). Hydraulic fracturing is a technique used to extract oil or natural gas from impermeable host rocks, which involves horizontal drilling into rock formations and injection of high-pressure fracturing fluid ( Williams et al. 2017 ; Schultz et al. 2020 ).

The organic contaminants of shale gas FPW include compounds injected in the fracturing fluid, compounds of the formation which are mobilized when being brought in contact with fracturing fluid, and products of physicochemical and biological transformation of organic fracturing chemicals. 32 It is anticipated that fracturing chemicals dominate in early flowback, whereas chemicals of formation …

Research - ConocoPhillips Center for a Sustainable WE2ST

This research project aims at exploring the fracturing efficiency of produced and flowback water treated to different levels by various water treatment technologies. The main objective of this research is to produce an effective fracturing fluid from O&G wastewater rather than generating fresh water or water for irrigation purposes.

Electrodialysis was used to treat high‐salinity ,flowback, water produced from hydraulic ,fracturing, operations in Marcellus and Barnett shale formations with a mixture of multivalent cations (Severin & Hayes, 2019). The impact of multivalent cations on fouling was examined, and efforts in fouling mitigation were reported.
