Abstract
Bubble/dew point pressure calculation, isothermal flash, and gas to oil ratio calculations are important in some applications such as petroleum production, processing, and transportation. Cubic equations of state are widely used for the prediction of phase behavior. The reservoir fluid consists of thousands of different components, which makes it impossible to identify them. A reliable prediction of phase behavior also needs an accurate representation of the critical properties and acentric factor. On the other hand, performing a phase behavior calculation by a large number of components requires a high computational time. In order to solve this problem, the composition of mixtures is usually presented in terms of the mole percent of pure hydrocarbons up to C6, and for hydrocarbons heavier than C6, it is grouped into a single carbon number group. Practically, the characterization of a heavy fraction of a reservoir fluid is performed by experimental and mathematical methods. Methods for the prediction of critical properties and the characterization of heavy fractions will be discussed in this chapter.
