3-phase fluid model based on three pseudo-components   C = \{ W, O, G \}:


W – water pseudo-component, which may include minerals  (assuming formation water and injection water composition is the same)

O –  dead oil pseudo-component 

G – dry gas pseudo-component


existing in three possible phases  \alpha = \{ w, o, g \}:

w – water phase, consisting of water component only

o –  oil phase, consisting of dead oil pseudo-component and dissolved natural gas pseudo-component (called solution gas)

g – gas phase, consisting of natural gas pseudo-component 



 it is basically a simplified version of Modified Black Oil model without volatile oil  R_v =0.


The accountable cross-phase exchanges are illustrated in the table below:
