The quantitative measure of volatile oil in wet gas:

$\begin{array}{l}R_v = \frac{V_{Og}^{\LARGE \circ}}{V_{Gg}^{\LARGE \circ}} = \frac{m_{Og}}{ m_{Gg}} \cdot \frac{\rho_G^{\LARGE \circ}}{\rho_O^{\LARGE \circ}}\end{array}$

where

$\begin{array}{l}V_{Og}^{\LARGE \circ}= \frac{m_{Og}}{\rho_O^{\LARGE \circ}}\end{array}$	STP volume of dead oil component of mass $\begin{array}{l}m_{Og}\end{array}$ and STP density $\begin{array}{l}\rho_O^{\LARGE \circ}\end{array}$
$\begin{array}{l}V_{Gg}^{\LARGE \circ}= \frac{m_{Gg}}{\rho_G^{\LARGE \circ}}\end{array}$	STP volume of natural gas component of mass $\begin{array}{l}m_{Gg}\end{array}$ and STP density $\begin{array}{l}\rho_G^{\LARGE \circ}\end{array}$

$\begin{array}{l}R_v(p, T)\end{array}$ is a cross-phase exchange coefficient and a function of pressure and temperature
