ABSTRACT: A new thermo-hydro-mechanical-geochemical numerical simulator, called TOUGHREACT-FLAC3DDM, has been developed. This simulator is based on the coupling of two well established numerical codes, TOUGHREACT, with thermo-hydro-geochemical (THG-C) modeling abilities, and FLAC3D, into which a developed elasto-plastic damage model has been implemented. We have validated TOUGHREACT-FLAC3DDM and the coupling approach with a series of laboratory tests. The developed simulator has been used to understand CO2 migration and its impacts on groundwater quality in the context of a Canadian field case. A typical scenario that represents relevant engineering conditions and risk levels has been carefully investigated.
