... throughout the reservoir. The GBO model requires PVT properties of hypothetical "binary" mixtures which are used to obtain actual fluid behavior. In the appendices we give methods for calculating these binary PVT properties based on correlations, material balance equations, and non-linear regression...

... of gas condensate reservoirs. The authors used the data available from standard CVD experiments and developed an algorithm to compute the black-oil PVT properties of gas condensate without the requirement of K-value model or equation of state (EOS) calculations. The method is rigorous, direct and simple...
