| description | <p dir="ltr">CO<sub>2</sub>-water-rock interactions can positively or negatively affect CO<sub>2</sub> injection, storage capacity, and stability. This study examines the geochemical and microstructural responses of Indiana limestone and Berea sandstone when exposed to CO<sub>2</sub>-saturated water at 50 °C over 14 days. Elemental analysis revealed significant calcium dissolution in both rocks, with a slight stabilization at higher pressures in limestone and a marked reduction in Berea sandstone. While XRD analysis detected mild mineralogical changes, SEM analysis (at magnifications reaching up to 50,000×) revealed significant microstructural degradation, particularly pronounced in sandstone. These findings suggest that although CO<sub>2</sub> exposure may initially enhance porosity, prolonged dissolution could compromise reservoir integrity, especially in siliciclastic sandstone formations. The observed differences in reactivity between the two rock types highlight the need for tailored CO<sub>2</sub> sequestration strategies, including careful reservoir selection and assessments of long-term storage stability.</p><h2>Other Information</h2><p dir="ltr">Published in: Ore and Energy Resource Geology<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.oreoa.2025.100110" target="_blank">https://dx.doi.org/10.1016/j.oreoa.2025.100110</a></p> |
