CO 2 convective mixing in saline aquifers has been widely studied numerically and experimentally. Reservoir heterogeneity is significant for CO 2 convective mixing and experimental studies are still limited. In this study, we have conducted a visualization of CO 2 convective mixing experiments in heterogeneous porous media at reservoir conditions using CO 2 and water. We have used a two-dimension Hele-Shaw cell, different glass beads of different permeability at porous media, and water solution with pH indicator. Glass beads were packed in a different way (horizontally and vertically) to generate the heterogeneity inside the test cell. We have studied transport velocity deviation due to the heterogeneity and effects of permeability transition zone together with the effects of boundary conditions. It was found out that having a low permeable layer below a high permeable layer restructure the flow of CO 2 fingers and dampens the CO 2 transport velocity. With the vertical permeability zones, having a high permeability zone accelerates CO 2 gravity transport through that zone which is a good representation for a fracture or a fault in the reservoir. CO 2 convection onset is governed by the vertical high-permeable layer. Boundary conditions have been dominant with the presence of high permeable zones. It also found out that the experimental results presented in this study match with the simulation studies that are available in the literature.

The high cost of the CO 2 sequestration in saline aquifers is a barrier to the implementation of them. However, a large portion of the cost is invested to purify and transport the CO 2 from the flue gas stream of the emission sources. Therefore, the possibility of injecting impure CO 2 will reduce the costs strongly. The diffusion coefficient is an important factor that plays a significant role in different aspects of the process. In spite of its importance, it is got less attention due to complex experimental procedures and low range of temperature and pressure applicability in the experimental conditions. To shed light on the effects of the impurity on the diffusion coefficient of CO 2 -water systems, two types of impurities (SO 2 and N 2 ) in two levels are considered in this study through the molecular dynamics simulation approach. Simulations are done on a wide range of pressure and temperature conditions to cover a wide range of operational conditions for CO 2 sequestration projects. The outcomes of these simulations were used in the direct numerical simulations to analyze the effect of the diffusion coefficient matrix changes on the CO 2 dissolution process such as dissolution flux, the motion and shape of convective fingers, and their patterns. Results indicate that impurity has a great impact on the
