Abstract:This book is a compilation on the results of a short-term research project, applied to a specific necessity of the petroleum industry, which, through a fraction of the production royalties, sponsors both partnerships and joint ventures with universities and other institutes of acknowledged know-how on both Irreversible and Phase-Equilibrium Thermodynamics. Its main objective is to establish separately the contributions of the isothermal gravitational field, thermal diffusion and molecular association phenomena to the compositional grading observed in petroleum fields. Starting from the experience gathered from other fields in the literature where these phenomena are noticeable, new premises, methods of calculation and parameter estimation were then applied to new case studies not published so far. Nothing prevents the thoughts employed in the examples presented here to be extended to other case studies, since one can always perform a parameter re-estimation for local contexts.
