  7. Abstract:
  8. In this study, two approaches were applied for estimating Minimum Miscibility Pressure (MMP). An oil sample from Yadavaran Field has examined by means of Carbon Dioxide Gas, South Pars Gas, and Association Gas in experimental approach. The experimental method used for estimating MMP is Slim-Tube. This kind of method is applied in industry widely. The results indicate that the MMP of Carbon Dioxide is low which denotes that the gas is even miscible around the Bubble Point Temperature of the oil sample. Moreover, the MMP of Association Gas and South Pars Gas is 3962 and 5150 psia, respectively. In simulation approach, Cell to Cell simulation method is used to estimate the MMP of the oil sample by means of PC-SAFT, Redlich–Kwong, Peng Robinson, and Modified Peng Robinson equations of state. The results of simulation indicate that PC-SAFT equation of state, which is originated from Statistical Thermodynamics, is more accurate than other equations of state which are based on Classical Thermodynamics. The minimum and maximum calculating error of PC-SAFT equation of state is 0.11% and 11.67%, respectively. PC-SAFT equation of state indicates better results by holding mean calculating error of 6.24%
