Microscopic reactive dynamics of CO2-brine-carbonate systems: Insights into pores, fractures and vugs

Key Points

• Findings illustrate the significant role of fractures in the transport of CO2, enhancing storage capabilities.
• Key evidence includes altered reactive dynamics observed in vugs compared to surrounding matrix features.
• Analysis of microscopic interactions within brine-carbonate systems provided deeper understanding of CO2 behavior.
• These insights support potential improvements in carbon storage strategies and the long-term stability of CO2.
