Viscosity of oil - Vasquez/Beggs correlation - P>Pb
Input(s)
\(\mu o d\): Oil viscosity at bubble point \((\mathrm{cP})\)
Rso: Solution oil gas ratio (fraction)
p: Pressure (psi)
\(p_{b}\): Bubble Point Pressure (psi)
Output(s)
m: Exponential Constant for Beggs Correlation (dimensionless)
\(\mu o\): Viscosity of Live-Oil (cP)
Formula(s)
\[
\begin{gathered}
m=2.6 *\left(p^{1.187}\right) * \exp \left(-11.513-8.98 *\left(10^{-5}\right) * p\right) \\
\mu o=\mu o d *\left(\frac{p}{p_{b}}\right)^{m}
\end{gathered}
\]
