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)
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:
