Beyond wettability: Flow regime and geological heterogeneity controls on CO2 trapping efficiency and dissolution behavior in saline aquifers

Key Points

• CO2 trapping efficiency is significantly influenced by flow regime and geological heterogeneity, affecting how effectively carbon is stored.
• Specific flow regimes were found to enhance CO2 dissolution behavior in saline aquifers under varying geological conditions.
• Observational analysis across multiple saline aquifers revealed different trapping mechanisms and behaviors based on geological structure.
• Findings highlight the necessity for enhanced models in carbon capture strategies to account for geological variability.
