Viscosity of binary and multicomponent hydrocarbon fluids at high pressure and high temperature conditions: Measurements and predictions

The experimental data obtained for these mixtures have been used to evaluate the performance of different viscosity models. The investigated viscosity models are the Lohrenz-Bray-Clark (LBC) correlation, the Pedersen correlation and a modified LBC correlation. Although the viscosity models were applied at challenging HPHT conditions, the predictions were in reasonable agreement with experimental results. In general, the Pedersen method showed slightly better viscosity predictions for the mentioned hydrocarbon systems.
