Viscosity is a very important parameter of the fluid flow in porous media. Generally, oil viscosity can be obtained in two ways, either by carrying out experimental measurements or by estimating a proper model. Due to the high expenses, and time wasting, literature models were applied to measure viscosity of crude oils. Whenever laboratory data obtained were made to find a best-fit correlation, due to the demand for mathematical equation of fluid flow for reservoir simulation. In this work, it is very important to use an accurate correlationsin calculating the oil viscosity at various operating conditions either for dead , saturated or undersaturated oils.Here, based on Libyan oil reservoirs data, accuracy confirmed by comparing the obtained results of the correlations and other ones with experimental for fifteen oil samples.
