# Solution gas oil ratio - Beggs-Standing correlation - P<Pb

## Input(s)

\(\mathrm{T}\): Temperature \((\mathrm{F})\)

\(\gamma_{g}\): Specific gravity of produced gas (fraction)

p: Pressure \(1(\mathrm{psi})\)

\(p_{o}\): Pressure at given API (psi)

## Output(s)

\(Y_{g}\): Constant (fraction)

\(R_{s o}\): Solution Gas Oil Ratio (fraction)

## Formula(s)

\[
\begin{gathered}
Y_{g}=0.00091 * T-0.0125 * p_{o} \\
R_{s o}=\gamma_{g} *\left(\frac{p}{18 * 10^{Y_{g}}}\right)^{1.204}
\end{gathered}
\]
