... injected gas and reservoir fluids. In this study, models were constructed to investigate the mechanisms of foam displacement in porous media using three-phase fractional flow theory and ternary diagrams. The strength of foam in the presence of oil was accounted for by using a mobility reduction factor (MRF...

However, the pressure drop is considerably lower suggesting that foam flows under a coalescence regime. foam pressure drop foam displacement homogeneous core saturation profile foam breakthrough flow in porous media surfactant solution saturation injection upstream oil...
