Volumetric shares of petroleum fluids phases V_\alpha saturating effective pore volume V_\phi:

In most popular case of a 3-phase fluid model this will be:
(4) | 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 |
