Oil density - Standing's correlation

Input(s)

$\gamma_{o}$: Oil Specific Gravity (fraction)

$R_{s}$: Solution Gas Oil Ratio (SCF/STB)

$\gamma_{g}$: Gas Specific Gravity (fraction)

$\mathrm{t}$: Temperature $(\mathrm{F})$

Output(s)

$\rho_{o}$: Oil density $\left(\mathrm{lbm} / \mathrm{ft}^{3}\right)$

Formula(s)

$$ \rho_{o}=\frac{62.4 * \gamma_{o}+0.0136 * R_{s} * \gamma_{g}}{0.972+0.000147 *\left(R_{s} *\left(\frac{\gamma_{g}}{\gamma_{o}}\right)^{0.5}+1.25 * t\right)^{1.175}} $$
