Abstract: By analyzing the characteristics of special oil and gas condensate systems, a new and applicable cubic EOS (Equation of State) is expanded to the special oil/gas systems. By calculating practical oil/gas system, an EOS is derived, which is applicable for the wide ranges of composition, temperature and pressure.

Key words: Condensate gas and oil, EOS, Dew Point, Critical Property, Gas Component, Hydrocarbon Composition, Phase Behavior Study
