Effect of Numerical Error Due to Heterogeneous Permeability on the Onset of Convection in CO2 storage

Abstract

Convective mixing in CO2 storage has been studied experimentally, numerically and theoretically using linear stability analysis. Perturbations that triggers convective fingers in these studies have been reported to be due to imperfections in experimental setup, due to numerical errors in simulations, and stated to be artificial in theoretical studies. In this work, the effect of numerical errors on the onset of convective mixing are investigated. Regions where convective downwelling fingers occur are observed to possess convergence problems. By assigning non-uniform permeability values to grid blocks near CO2 and brine interface, the numerical error in these grid blocks is exacerbated. The number of grid blocks with non-uniform permeability values affects the number of downwelling convective fingers but do not influence the time of onset of convection.
