Fracturing fluid migration is a multiphase flow problem in which gas or oil, (the nonwetting phase) contained in the shale interacts with H,F 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 ].

Fluid couplings (fluid flywheels)(Pg. 66) A fluid coupling is a device which allows a controlled amount of slip between input and output between the drive and driven machine, with no mechanical contact. The fluid coupling consists of a pump impeller (on the input shaft) and a runner (on the output shaft). Both.
