Numerical Study of Chemical Fluid-Solid Interaction on Pore-Scale

Summary We present a numerical algorithm for the reactive transport simulation at the pore scale. The algorithm is based on the direct evaluation of the pore-to-matrix interface evolution due to chemical fluid-solid interaction. Using this algorithm we performed a series of numerical experiments simulating various physical and chemical conditions. After that we estimated the changes in the pore space topology and illustrated that these topological measure can be used to characterize completely different core matrix dissolution regimes, with different porosity-to-permeability-to-tortuosity correlations.
