Application to Petroleum Engineering of Statistical Thermodynamics – Based Equations of State

Abstract: Résumé -Application des équations d'état basées sur la statistique thermodynamique, aux besoins pétroliers -L'utilité des équations d'état cubiques pour l'ingénieur pétrolier a été démontrée depuis de nombreuses années. Leur pouvoir prédictif reste cependant limité. De nouvelles équations d'état, basées sur des principes de mécanique statistique, ont été développées depuis environ 15 ans, et leur maturité est telle qu'elles sont maintenant de plus en plus utilisées par l'ingénieur. Dans cette publication, nous… Show more

“…The breakthrough in the modeling of aqueous systems came with the development of association models such as the statistical associating fluid theory (SAFT) [18], the associatedperturbed-anisotopic-chain-theory (APACT) [5] and the cubic plus association (CPA) EoS [18][19][20]. All these models have previously been applied to the description of the hydrocarbon/water mutual solubilities and the SAFT EoS was already applied for the prediction of the thermodynamic inhibiting effect of methanol on gas hydrate formation [21].…”

“…The types of mixtures whose phase behavior EOS can predict with accuracy has gradually expanded and now include many systems with polar substances, polymers, and electrolytes [4][5][6][7][8][9]. A drawback is the effort required to calculate thermodynamic properties, generally larger with EOS than with activity coefficient models, but as computers become increasingly faster, this tends to become a less important issue.…”
