Comparison of Dead Oil Viscosity and Gas Solubility Empirical Correlations
Publication Date : 25/04/2016
Reservoir fluid properties are very important physical properties that control the flow of oil through porous media and pipes. They used comprehensively in most of petroleum engineering applications such as drilling engineering, reservoir engineering, and production engineering. Perfectly, these properties should be obtained from actual laboratory measurements on samples collected from the bottom of the wellbore or at the surface. Quite often, however, these measurements are either not available, or very costly to obtain. For these reasons, it is necessary for the petroleum engineer to find an accurate, quick and reliable method for predicting the reservoir fluid properties. Therefore, the concept of numerical correlation equations has been proposed to the petroleum industry to alleviate all difficulties in reservoir fluid properties determination. For this study, more than 50 published black oil empirical correlations for dead oil viscosity and gas oil ratio were collected and summarized from 1946 till now in chronological order. The comparison results are presented graphically and also summarized in tables that can be used to guide reservoir fluid properties correlations users in selecting the most appropriate black oil empirical correlations.
