چکیده:

In order to describe phase behavior of reservoir fluids, well-predict phase equilibrium and volumetric properties of gas condensate during production operation a true characterization procedure is required for boiling point and plus fractions of reservoir fluids. Since there isn’t a general distribution function for petroleum fractions and gas condensates, developing a distribution function have been the main objectives of many studies. In this study a comprehensive distribution function is presented for the Iranian gas condensate reservoirs. Since in the reservoir fluids commonly used distribution function are not valid for larger carbon numbers, in the present work the new distribution function truncated at some finite value of the characterization variable. The results calculated using the new distribution function is in good agreement with experimental data obtained from reservoirs. The results obtained from nine commonly used distribution functions are also compared with the new distribution function and it is shown the accuracy of the new function.
