Developing new correlation for predicting of dew point

Undoubtedly, dew point pressure is a key parameter for determination of gas condensate phase diagram. Dew point prediction is a crucial issue for obtaining accurate performance of gas condensate reservoir. In this study, three empirical correlations are evaluated. These correlations are function of hydrocarbon components and non-hydrocarbon components, plus fraction and reservoir temperature. Next, the new hybrid correlation is developed as function Elsharkawy and Shokir correlations using 131 experimental data extracted from open literature. The results of new predicting correlation showed 11% improvement with respect to the best applied correlation Shokir.
