Total ,flowback, at Damme 3 from 20 November 2008 to 12 December 2009 amounted to 3,058 m 3 . The proportion of formation water, 69 %, and hydraulic ,fracturing fluid,, 31 %, in ,flowback, were derived from Fig. 3. This shows that only 945 m 3 of the hydraulic ,fracturing fluid, were recovered at this stage.

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.
