Design of a 2-D Cementation Experiment in Porous Medium Using Numerical Simulation

Abstract

Résumé -Dimensionnement numérique d'une expérience 2D de colmatage en milieu poreuxEn vue de contribuer à la validation et à la qualification des outils de simulation du transport réactif, une expérience de laboratoire, dans laquelle écoulement, transport par advection/dispersion et transformations physicochimiques affectant le milieu poreux sont fortement couplés, a été conçue et simulée numériquement. Différents montages expérimentaux ont été explorés et testés. La solution retenue met en jeu successivement la précipitation et la perforation d'un obstacle colmatant composé d'oxalate de calcium. Avant qu'une expérience réelle puisse être construite, ce problème est proposé à la communauté scientifique en tant que benchmark numérique. Les simulations qui en sont présentées ici ont été réalisées à l'aide du code couplé chimie-transport Hytec (CIG, École des mines, France).

Modelling glass alteration in an altered argillaceous environment

“…The role of clogging has also to be assessed with regard to mechanical stress, e.g., shear stress, with might prevent any protective function from being effective on the long term. The complexity of the mechanisms at play when the porosity is vanishing due to geochemical interactions in a porous media calls for further theoretical and experimental investigation [22].…”

Gas-Water-Rock Interactions Induced by Reservoir Exploitation, CO2 Sequestration, and Other Geological Storage

“…Paper [15] combines the two aspects. A second group of articles, [16][17][18], focuses on the question of model calibration, or validation, that can be drawn from well defined experiments. Finally, papers [19][20][21][22][23] present new or improved modelling tools from a very large range of topics, from liquid-vapour equilibria to more prospective future ab initio molecular calculations, through activity corrections, coupling between chemistry and mechanics, and solid solutions.…”

Evolution of a Generic Clay/Cement Interface: First Reactive Transport Calculations Utilizing a Gibbs Energy Minimization Based Approach for Geochemical Calculations

“…They observed clogging in the clay or cement compartment depending on the setup of their scenario. Clogging times were variable between 40 years and 50,000 years Two-dimensional modeling of the hyperalkaline plume around a cementitious repository has been done by working groups in France 9) . To simulate the process interactions, various models that couple chemistry with mass transport have been developed in the past.…”
