A model is presented for the temperature, pressure, and composition effects on the viscosity of crude oils and their mixtures. The proposed three-parameter model uses Walther's (or ASTM) viscosity-temperature correlation and its modification to include the effect of pressure on viscosity. The stepwise modeling approach is illustrated using published viscosity data for three crude oils and their binary and ternary mixtures. One of the three parameters in the viscosity model is found to be constant, and simple correlations are provided for the remaining two parameters in terms of crude oil mixture density at 25{degrees}C. The validity of the viscosity model is demonstrated by a good match between the calculated and experimental crude oil viscosities.
