The quantitative measure of volatile oil in wet gas:
R_v = \frac{V_{Og}^{\LARGE \circ}}{V_{Gg}^{\LARGE \circ}} =
\frac{m_{Og}}{ m_{Gg}} \cdot \frac{\rho_G^{\LARGE \circ}}{\rho_O^{\LARGE \circ}}
where
V_{Og}^{\LARGE \circ}= \frac{m_{Og}}{\rho_O^{\LARGE \circ}} | STP volume of dead oil component of mass m_{Og} and STP density \rho_O^{\LARGE \circ} |
V_{Gg}^{\LARGE \circ}= \frac{m_{Gg}}{\rho_G^{\LARGE \circ}} | STP volume of natural gas component of mass m_{Gg} and STP density \rho_G^{\LARGE \circ} |
R_v(p, T) is a cross-phase exchange coefficient and a function of pressure and temperature
