The Oil Viscosity Correlations: A Simulation Approach

Abstract

Over the years, different authors have proposed many oil viscosity correlations for various crude oil mixtures (dead, saturated, or undersaturated) from all over the world. Authors tend to support their own correlations, which are developed for specific sets of hydrocarbon mixtures. When tested on other data sets, however, they do not perform as anticipated. The authors considered a total of 13 undersaturated correlations for a sharp review from a simulation perspective. They came to the conclusion of supporting the use of undersaturated viscosity correlations that use the exponential parameterized pressure differential form. Thus a new fine tuning parameter, which sets a sound basis for local data sets to be accounted for, has been proposed.
