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 ].
