Saturated Oil Viscosity

In this spreadsheet, just type in the required information and press the compute button. Scroll down for more info.

Rs
scf/STB
Gamma_API
API
T
deg F
Viscosity
cp
Oil Viscosity for saturated systems (after Beggs and Robinson).
mu_os = A*mu_od**B
Where
mu_os = saturated oil viscosity, cp
mu_od = dead oil viscosity, cp, = 10**x - 1.0,
x = T**(-1.163)*exp(6.9824-0.04658*Gamma_API),
T = Temperature of interest, F,
Gamma_API = stock tank oil gravity, API,
A = 10.715*(Rs+100)**(-0.515),
B = 5.44*(Rs+150)**(-0.338),
Rs = solution GOR, scf/STB. For more info, refer to Vasquez & Beggs, Lasater, or Standing.
