Arithmetic average across all reservoir fluids phases :


3-phase Oil + Gas + Water fluid model


p = \frac{1}{3} \, ( p_w + p_o + p_g )



2-phase Oil + Water fluid model


p = \frac{1}{2} \, ( p_w + p_o )



2-phase Oil + Gas fluid model


p = \frac{1}{2} \, ( p_o + p_g )



2-phase Gas + Water fluid model


p = \frac{1}{2} \, ( p_w + p_g )
