18/6/2014, · The process of hydraulic fracturing requires the use of a fracturing fluid, which when pressurised generates fractures, invades the shale reservoir and then is returned to the surface through the wellbore after fracturing has been completed (Anderson et al. 2010; Gregory et al. 2011)—this is termed flowback fluid.

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 ].
