Coupled Geomechanical and Geochemical Responses of Carbonate-Bearing Sandstone Reservoirs to CO₂ Injection: A Critical Review of Instability Mechanisms, Risk-Assessment Frameworks, and Implications for Energy Storage
The safe and permanent geological storage of carbon dioxide (CO₂) in deep carbonate-bearing sandstone formations requires a rigorous understanding of the coupled geomechanical and geochemical responses of the host reservoir to sustained fluid injection. Fluid injection simultaneously raises pore pressure, reduces effec...
