Volumetric shares of petroleum fluids phases saturating effective pore volume :
s_\alpha = \frac{V_\alpha}{V_\phi} |
so that
\sum_\alpha V_\alpha = V_\phi |
and
\sum_\alpha s_\alpha = 1 |
For 3-phase Oil + Gas + Water fluid model this is going to be:
s_w + s_o + s_g = 1 |
where
water phase saturation at reservoir location | |
oil phase saturation at reservoir location | |
gas phase saturation at reservoir location |
