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)

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