Eyton (1987) discussed the sources and magnitudes of various types of errors that may be encountered in lab data for gas condensates. Eyton observed that liquid volumes tend to be underestimated for both...

...) for black oil and a higher GOR for gas condensate. Critical property shift has a consistent effect on both the black oil and gas condensate, resulting in a lower GOR. It should be noted that the effect of capillary pressure on production is suppressed for both fluids with the shifted critical property...

... perturbation parameters. In this paper, we extend the PnA method to lighter fluids, such as gas condensates, volatile oils, and near-critical fluids. The main novelty of the new PnA method is that it considers proper interrelationship (ψ = a/b 2 ) between the attraction (a) and covolume (b) parameters...

... is only valid for linear systems. In practice, it is also used, with pseudo-pressures, for dry gas, and even for gas condensate and volatile oil below saturation pressure. As these systems are highly non-linear, there has been some concerns about the validity of such an approach. This paper investigates...
