  abstract: Carbon dioxide (CO₂) sequestration is defined as the removal of gas that would be emitted into the atmosphere and its subsequent storage in a safe, sound place. CO₂ sequestration in underground formations is currently being considered to reduce the amount of CO₂ emitted into the atmosphere. However, a better understanding of the chemical and physical interactions between CO₂, water, and formation rock is necessary before sequestration. These interactions can be evaluated by the change in mineral content in the water before and after injection, or from the change in well injectivity during CO₂ injection. It may affect the permeability positively due to rock dissolution, or negatively due to precipitation. Several physical and chemical processes cover the CO₂ injection operations; multiphase flow in porous media is represented by the flow of the brine and CO₂, solute transportation is represented by CO₂ dissolution in the brine forming weak carbonic acid, dissolution-deposition kinetics can be seen in the rock dissolution by the carbonic acid and the deposition of the reaction products, hydrodynamic instabilities due to displacement of less viscous brine with more viscous CO₂ (viscous fingering), capillary effects and upward movement of CO₂ due to gravity effect. The objective of the proposed work is to correlate the formation damage to the other variables, i.e. pressure, temperature, formation rock type, rock porosity, water composition, sulfates concentration in the water, CO₂ volume injected, water volume injected, CO₂ to water volumetric ratio, CO₂ injection rate, and water injection rate. In order to achieve the proposed objective, lab experiments will be conducted on different rock types (carbonates, limestone and dolomite, and sandstone) under pressure and temperature that simulate the field conditions. CO₂ will be used at the supercritical phase and different CO₂-water-rock chemical interactions will be addressed. Quantitative analysis of the experimental resu…
