Evaluation of oil viscosity is an important deal in the design of various operations in oil fields and refineries. Therefore, the variety in viscosity of crude oil, depends on pressure and temperature . In this work, different oil samples from Libyan reservoirs were selected and supplementary data were collected from published literature. Chew-Connally , Beggs-Robinson , Labedi  and modified kartoatmodjo  correlations are applied to the acquired data set and a comprehensive error analysis is performed based on a comparison of the predicted value with the experimental value. Results concluded that Beggs-Robinson model gives the lowest value of absolute average deviation (AAD %) 21.19 % compared with the other models promoting this correlation for more applications.
