Volumetric share of petroleum fluids saturating porous reservoir:
(1) | \sum_\alpha s_\alpha = 1 |
For 3-phase Oil + Gas + Water fluid model this is going to be:
(2) | s_w + s_o + s_g = 1 |
where
s_w = s_w({\bf r}) | water phase saturation at reservoir location \bf r |
s_o= s_o({\bf r}) | oil phase saturation at reservoir location \bf r |
s_g= s_g({\bf r}) | gas phase saturation at reservoir location \bf r |
