Abstract: The storage of CO 2 has become an important worldwide problem, considering that an excess of CO 2 in the Earth’s atmosphere causes dramatic changes in its climate. One possible solution is to remove the excess of CO 2 from the atmosphere, capture it in the process of creation, and store it safely, negating the possibility of its return into the atmosphere. This is the process of Carbon Capture and Storage (CCS). In the following paper, the authors investigate horizontal saline aquifers and their ability to store CO 2 . The authors’ application of sensitivity analysis on horizontal migrations uncovered that CO 2 permeability and aquifer porosity have a considerable impact on horizontal migrations. During the migration process, CO 2 can reach tens of kilometers from its injection point. By introducing effective CO 2 density to the conduction velocity term, the authors showcase that the convection-diffusion equation for compressible fluids can be replaced with the equation for incompressible fluids. The buoyancy factor in convective velocity is as density dependent as in conduction velocity. By means of introducing an effective density to the aforementioned term, the process of transport via variable convective velocity can be substituted for a process which is effective, constant, and not density dependent.
