The quantitative measure of solution gas in live oil:

$\begin{array}{l}R_s = \frac{V_{Go}^{\LARGE \circ}}{V_{Oo}^{\LARGE \circ}} = \frac{m_{Go}}{ m_{Oo}} \cdot \frac{\rho_O^{\LARGE \circ}}{\rho_G^{\LARGE \circ}}\end{array}$

where

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

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