In this study, density-driven natural convection in porous media associated with Rayleigh-Taylor instability was visualized by X-ray computed tomography to investigate the effect of the thickness of the diffusing interface on convection. The thickness of the interface was changed by molecular diffusion with time, and the effective diffusivity in a porous medium was estimated. Compared with the thick interface, for the thin interface, many fine fingers formed and extended rapidly in a vertical direction. The onset time of natural convection increased proportionally with the thickness of the interface, being correlated with Rayleigh number and Péclet number. For the thinner initial interface, the finger number density increased more rapidly after onset and reached a higher value. Next, we discussed the mass transport in Rayleigh-Taylor convection to show how dispersion affects mass transport based on finger extension velocity and concentration in fingers. Increasing the interface thickness delayed the onset of convection, while the finger extension velocity remained the same. The reduced finger extension velocity changed nonlinearly with the Péclet number, reflecting the effect of dispersion. High transverse dispersion and longitudinal dispersion quickly reduced finger density. Transverse dispersion between ascending and descending fingers decreased the density; the density decreased linearly along the finger on both sides of the symmetric plane. As a result, the Sherwood number was proportional to the Rayleigh number, whereas the coefficient changed nonlinearly with Péclet number because of dispersion, reflecting the nonlinear dependences of the reduced velocity and the reduced density difference on Péclet number.

In carbon dioxide capture and storage (CCS), the shift to the dissolution trapping of CO 2 in brine from the capillary trapping and physical trapping by caprock depends on the mass transfer associated with density-driven natural convection at a reservoir scale. In this study, natural convection between miscible fluids in a porous medium with layered structure is visualized three-dimensionally by means of an X-ray microtomography. When a finger associated with Rayleigh-Taylor convection passes through the interface of the layered heterogeneous structure with an increasing permeability, because of an increase in the finger extension velocity, the finger diameter and the concentration in the finger decrease. On the other hand, when a finger passes through the interface with a decreasing permeability, the finger diameter increases and the concentration in the finger remains the same, which suggests that the change in the concentration in the finger shows nonlinearity against the permeability. In present study, because the thickness of the initial interface is lower than the thickness of the layer structure, the onset time of convection depends on the property of the porous medium just around the initial interface. In addition to that, the finger extension velocity depends on the local property of the porous medium and the empirical equation derived for the uniform porous medium agrees well with the local finger extension velocity estimated for each layer.

“…This vertical flow (gravity current) can however be immobilized due to capillary trapping. Subsequently, CO 2 during vertical flow also dissolves into the brine at the CO 2 /brine interface (Riaz and Cinar, 2014). Zhou et al (1994) defined the ratio of gravity to viscous forces with a number (N gv ) which describes a two-phase flow in a heterogeneous medium.…”

a b s t r a c t CO 2 injection for storage in subsurface geologic medium is one of the techniques developed in the past years to mitigate anthropological CO 2 . Prior to CO 2 injection, it is essential to predict the feasibility of medium in terms of storage capacity, injectivity, trapping mechanisms, and containment. There have been many studies regarding techniques which can be applied to ensure the safety of CO 2 injection. However, there are few studies indicating the importance of capillary trapping during and after CO 2 injection. The aim of this study is to review the fundamentals of injectivity and its relationship with capillary trapping for CO 2 storage in depleted oil and gas reservoirs. Considering the number of effective parameters which are associated with the injectivity and capillary trapping, it is recommended to perform a comprehensive analysis to determine the optimum injection rate and safe storage medium before operation.
