In this work, the experimental data collected from eight wells of gas condensate reservoirs in south of country and quality control was performed on the mass balance and equilibrium review. It goes down to the characterization of plus fraction, various methods such as exponential function, modified exponential function ,gamma function, Ahmed and four coefficient model methods are introduced and evaluated. Then the four coefficient model has been developed and four new correction factor were calculated for data and the calculation algorithm was proposed. Finally, the percentage absolute deviation and average absolute deviation of different methods of splitting the mole fraction and these methods are compared with each other. Results indicate that modified exponential function method and four coefficient modified model has been developed, generates less error in the calculations.
