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)

$$ \begin{gathered} m=2.6 *\left(p^{1.187}\right) * \exp \left(-11.513-8.98 *\left(10^{-5}\right) * p\right) \\ \mu o=\mu o d *\left(\frac{p}{p_{b}}\right)^{m} \end{gathered} $$
