Effect of reactive surface area of minerals on mineralization and carbon dioxide trapping in a depleted gas reservoir.

Highlights: [•] Experimental measurement of reactive surface area of the minerals. [•] Monte Carlo uncertainty analysis to elaborate the importance of surface area. [•] Sequestered CO₂ as a mineral (SMCO₂) varied between 3 and 9kg/m³ of medium. [•] SMCO₂ increased 80% by increasing the surface area of quartz by a factor of 3. [•] Dawsonite precipitation showed dependency on kaolinite and K-feldspar dissolution. [Copyright &y& Elsevier]
