CO 2 geological storage in saline aquifers results in acidification of resident brine. Chemical
reactions between acidified brine and rock minerals lead to dissolution and precipitation of …

Dissolution of CO 2 into saline aquifers can lead to the development of buoyancy-driven
convection in the brine which enhances the efficiency of CO 2 transfer. We analyze here …

This paper presents a review of the state-of-the-art on interphase mass transfer between
immiscible fluids in porous media with focus on the factors that have significant influence on …

When CO 2 is injected into aquifers, CO 2 will dissolve into the water phase. CO 2
dissolution initiated by diffusion, will increase the density of the water phase and thereby …

When carbon dioxide (CO2) dissolves into water, the density of water increases. This
seemingly insubstantial phenomenon has profound implications for geologic carbon …

Chemical reactions can interplay with hydrodynamic flows to generate chemo-hydrodynamic
instabilities affecting the spatio-temporal evolution of the concentration of the chemicals. We …

Understanding and predicting physical and chemical trapping mechanisms are important for
designing successful CO 2 storage projects. The processes have been investigated …

In modeling of geological carbon storage, dissolution of supercritical CO 2 (scCO 2) is often
assumed to be instantaneous with equilibrium phase partitioning. In contrast, recent core …

The density driven convection phenomenon is expected to have a significant and positive
role in CO 2 geological storage capacity and safety. But predictions on reservoir time and …

Pools of carbon dioxide are found in natural geological accumulations and in engineered
storage in saline aquifers. It has been thought that once this CO2 dissolves in the formation …
