Hydraulic ,fracturing, is a highly water intensive process that requires cross-linked gel fluids for vertical wells and slick-water fluids for horizontally drilled wells. The cross-linked gel ,fluid, usually has a high viscosity to transport sand, ceramics, and other proppant materials to induce fractures in the formation.

A portion of the frac ,fluid, remains in the formation after the ,fracturing, process is complete, which could potentially contribute to deleterious microbially induced processes in natural gas wells. Here, we report on the geochem. and microbiol. properties of frac and ,flowback, waters from two newly drilled natural gas wells in the Barnett Shale in North Central Texas.

1/8/2016, · The composition and concentration of flowback water can vary dramatically between different shale formations, as a function of well life, and based on the fracking process (Haluszczak et al., 2013). Due to the challenges and high cost of treating the wastewaters, Class II, well injection, is the most common disposal method in some regions, such as Texas.

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,.”
