Hydraulic ,fracturing, for natural gas extn. from shale produces waste brine known as ,flowback, that is impounded at the surface prior to reuse and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compds., and result in biocorrosion that complicates water and waste management and increases prodn. costs.

Multistage hydraulic ,fracturing, is a key technique for the effective exploitation of tight reservoirs. In the process of multistage hydraulic ,fracturing,, a large amount ,of fracturing fluid, is injected into the formation. However, field data show that the ,flowback, rate of the ,fracturing fluid, after ,fracturing, is generally no higher than 30% [1].

1/4/2013, · After adding guanidine gum fracturing fluid, there was nearly no change in proppant bondability, some proppant started to flow when the bottle was tilted to 70 degrees, as shown in Fig. 7a. After adding D-60 emulsion breaker for 1 hour, chemical reaction completed, the liquid became turbid, with cementa- tion degree nearly the same, as shown in Fig. 7b.
