Abstract

This work investigates the effect of tilt, homogeneity and heterogeneity of deep saline aquifers on the onset time and critical wavelength of convective mixing in carbon-dioxide sequestration. This is done through numerical simulations and analytical calculations for aquifers tilted at various angles from the horizontal. Influence of convergence errors on the onset of convection and effect of grid sizes is also studied. Results show that an increase in average permeability reduces the onset of convection. In addition, an increase in tilt results in a slight increase in onset time and also faster propagation of convective fingers. Good knowledge of aquifer characteristics will ensure security of carbon sequestration in saline aquifers.
