CO2 storage in Deep Saline Aquifers (DSAs), is considered one of the promising options for large-scale reductions in CO2 emissions. The long-term storage of CO2 in DSAs depends on the chemical trapping mechanisms (viz., dissolution and mineral), which are governed by the miscible interactions of CO2 and brine namely (i) dissolution and (ii) diffusion of CO2 in brine present in the reservoir rocks of DSAs. Besides, these interactions might also alter the petrophysical and geomechanical properties of the reservoir rocks, especially carbonates, which in turn might induce geohazards (induced seismicity, ground deformation, caprock integrity, leakage of CO2). This calls for precise quantification of the parameters that control these interactions and understanding their variations with in-situ aquifer conditions (pressure, temperature, brine salinity) and reservoir rock characteristics (porosity, permeability). A comprehensive review of the experimental studies reported in the literature has been carried out in this context. The paper presents a detailed synthesis and interpretation of data available in the literature and highlights their limitations and potential ways forward. The review suggests that the insight from this exercise would be useful for a robust and accurate estimation of CO2 storage capacity, firstly, followed by planning appropriate injection schemes with reduced risks of geohazards.
