Modeling Pathways and Stages of CO2 Storage

E Holzbecher


The storage of CO2 in deep geological formations can be partitioned in three stages: diffusion, early and late convection. Convection emerges as a phenomenon of coupled flow and transport in porous media. For the characterization of the three stages we use numerical experiments with perturbations of a reference homogeneous situation. We explore the effect of different type and size of perturbations. The simulations show that the onset of the convection state depends strongly not only on the perturbations, but also on settings of the numerical method. Moreover it is found that the early convection state may consist of several peaks and is thus more complex than in the idealized simple concept of a single peak. For the late convection stage the decrease of the total mass transfer into the system is generally confirmed, within uncertainty margins.
