I study reactive transport in stressed, deformable porous media, where fluid flow, dissolution of the solid matrix and geomechanics interplay through changes of the rock microstructural properties (so-called “chemo-mechanical compaction”). In particular we are interested in understanding the controlling parameters for the evolution of the hydrological and mechanical properties. This process plays a key role in diagenesis of rocks, enhanced energy recovery, and CO2 sequestration. We investigate this via pore-scale numerical simulations using a novel numerical model which provides a mechanistic representation of the aforementioned mechanisms. Our numerical results will be compared to core-flooding experiments.
