Algorithm of PVT parameters of gas condensate mixture for compositional modeling of Achim deposits

The causes affecting the accuracy of fluid modeling are provided in the article by the example of gas condensate mixturessaturating the Achim deposits of Urengoyskoe oil and gas condensate field. The algorithmis recommended for selecting a sequence of adjusting and calculating procedures allowing obtain adequate models of gas condensate mixtures. The model of formation gas isused for compositional reservoir simulation modeling of the license site of Urengoyskoe oil and gas condensate field.
Results
