Oil formation volume factor - Standing's correlation

Input(s)

$\mathrm{R}_{\mathrm{s}}$: Gas Oil Ratio (SCF/STB)

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

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

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

Output(s)

$\mathrm{B}_{\mathrm{o}}$: Oil FVF (RB/STB)

Formula(s)

$$ \mathrm{B}_{\mathrm{o}}=0.9759+0.00012 *\left(\mathrm{R}_{\mathrm{s}} *\left(\frac{\gamma_{\mathrm{g}}}{\gamma_{\mathrm{o}}}\right)^{0.5}+1.25 * \mathrm{t}\right)^{1.2} $$
