Geochemical modeling of water-gas-rock interactions. Application to mineral diagenesis in geologic reservoirs; Modelisation geochimique des interactions eau-gaz-roche. Application a la diagenese minerale dans les reservoirs geologiques

摘要: The Ph.D. report describes a conceptual and numerical model for simulating gas-water-rock interaction during mineral diagenesis of sediments. The main specific features of this model are the following: applicable to open systems, half-implicit resolution numerical method, feedback on the texture evolution (grain model), existence of a gas phase, oxido-reduction phenomena.
