Dissolution-driven convection in partially miscible systems has regained much interest in the context of CO$_2$ sequestration [1]. A buoyantly unstable density stratification can build upon dissolution of CO$_2$ into brine, thereby driving convection. Dissolution and convection are known to improve the safety of the sequestration process by reducing the risks of leaks of CO$_2$ to the...
Dissolution trapping is one of the mechanisms that contributes to stable storage of carbon dioxide (CO2) in deep geologic formations with brine. Basic to the process is the supercritical CO2 (scCO2) dissolving in the formation brine and the subsequent mixing of dissolved CO2 and brine in the deeper zones of the formation. In most conceptual models, it is assumed that the mixing is controlled...
It is widely excepted [1] that CCS (Carbon Capture and Storage) could play a major role in mitigating climate change associated with CO2 emissions. Variety of industrial scale of CCS projects provide strong empirical support for the view that CO2 storage can be implemented safely. Nevertheless, many uncertainties remain regarding the security of underground storage. The major technical concern...
