The study found that: artificial fracture surface ,of fracturing fluid, seepage is the shale reservoir ,flowback, rate is generally lower than 30% of the main reasons. In view of the Sichuan Basin shalesamples,a lots the experiment of spontaneous infiltrationabsorption,compared did been with the sandstone in the Ordos Basin and the volcanic rocks in the Songliao Basin.

Flowback, is the portion of the injected ,fracturing fluid, that flows back to the surface, along with oil, gas, and brine, when the well is produced. An estimated 90% of ,flowback, in the United States is disposed of into deep EPA-licensed Class II disposal wells , with the remaining less than 10% reused, evaporated, used for irrigation, or discharged to surface streams under an NPDES permit.

Osmotic potential can increase or decrease the amount of imbibition depending on the salinity of the ,fracturing fluid,, brine, and mineralogy of the shale [Makhanov et al., 2014]. The addition of surfactants can reduce the surface tension and modify wettability, thus ,influencing, imbibition [Makhanov et al., 2014; Mirchi et al., 2015].

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 ].

At the end ,of fracturing,, the fracture ,fluid, was broken by a breaker to reduce molecular weight and ,fluid, viscosity. Therefore, the ,fluid, that remains underground may mostly be the gel breaking liquid. Thus, it is important to investigate the influence of gel breaking liquid on the stability of emulsion.
