Modelling fluid-rock interaction induced by the percolation of CO2-enriched solutions in core samples:: The role of reactive surface area

Modelling Fluid-Rock Interaction Induced by the Percolation of CO2-Enriched Solutions in Core Samples: The Role of Reactive Surface Area - Understanding the fate of CO2 disposed in aquifers or depleted hydrocarbon fields is partly based on the use of reaction-transport models, able to predict the possible interaction between acidified waters and the minerals. The results delivered by such models depend on many parameters and hypotheses, of which some are still poorly constrained. A key issue is how to transpose kinetics of a mineral reaction to a representative rock system, from data acquired in laboratory experiments involving controlled mineral powders under high water-to-mineral ratio.
