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