DEVELOPMENT OF APPLICATION MAPS FOR PVT PROPERTIES CORRELATIONS AS GUIDELINES FOR CORRELATIONS SELECTION

Abstract

Reservoir fluid properties (PVT properties) form the basis of many petroleum engineering calculations. The preferred way to determine the PVT data is by laboratory experiments on reservoir fluid representative samples. However, it is sometimes hard to obtain such samples and the engineer is left to estimate PVT properties from empirical correlations. The main target of the present research is to build Application Maps system that use groups of correlations to calculate input data that are used to evaluate correlations. Hence, application maps evaluate groups of correlations with complicated errors instead of single correlations with simple errors. The overall error that is resulted from using the Application Maps is 16.75%.
