چکیده انگلیسی
Results show that coefficients of 4CM are not universal and should be calculated for each fluid type, specifically. To do so, composition analysis must be reported at least to C14+. According to the results, different fluids exhibit different molar distribution; some are continuous, while some show discontinuity only in C8 and some show discontinuity in both C8 and C13. Therefore, 4CM with coefficients introduced by Raffie et al. may unable to model various molar distribution behaviors, as it is developed based on samples which all have discontinuities in both C8 and C13. However, when coefficients of 4CM are obtained for a specific reservoir, they give the best prediction of molar distribution when apply to other samples of the same reservoir too. Results also show that, by optimizing the alpha parameter in 3-parameters gamma distribution function, this model is being capable of predicting discontinuity in C8, if any. So, it is still the powerful method in predicting molar distribution of the fluid.
