• Mineral Carbonation: carbon dioxide can react with the minerals, fluids, and organic matter in the geologic formation to forms stable compounds/minerals; largely calcium, iron, and magnesium carbonates.

• Solubility trapping: carbon dioxide can be dissolved into a liquid – water and/or oil.

• Hydrodynamic Trapping: carbon dioxide can be trapped as a gas under low-permeability cap rock (much like natural gas is stored in gas reservoirs).
