... equation-of-state models that have become industry standards. In conjunction with our comparative study, we assess the accuracy of several mixing rules and empirical correlations for estimating pseudocritical and pseudoreduced properties used as input for the EOS models. The Concept of Natural Gas...

... of incomplete surface and/or downhole separation. Given this reality, the PVT analysis of any fluid sample with an equation-of-state (EOS) model demands that the results are verified with independent measurements. Our analyses of many samples show that a good correspondence exists between the PVT-derived...
