Oil formation volume factor - Standing's correlation

Input(s)

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

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

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

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

Output(s)

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

Formula(s)

Bo=0.9759+0.00012(Rs(γgγo)0.5+1.25t)1.2\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}
