When using equations of state to predict the phase behavior of hydrocarbon mixtures, problems occur with the C7+ fraction that exists in such mixtures. Minimizing such problems requires breaking down (splitting) the C7+ fraction into a number of pseudo-components with a single carbon number; e.g. C7, C8, C9.., etc. Extensive compositional analyses of too many reservoir fluids from all over the world have shown exponential molar distributions (mole fraction/molecular weight relation) of the C7+ pseudo-components. Hence exponential methods are extensively used by many researchers as a first choice for splitting the C7+ fraction.
