Geo-sequestration of Carbon Dioxide in Saline Aquifers: Experiments on Capillary Trapping
Sequestration of CO2 in geological formations is considered a promising alternative to minimize CO2 emissions. In particular, deep saline aquifers are considered prime candidates for geo-sequestration due to their large potential storage capacity. However, little is known about aquifers structure, physical and chemical properties, when compared to other geological formations, such as exhausted oil/gas fields and unminable coal seams. Current research shows that structural trapping, dissolution, mineral, and capillary forces contribute to CO2 immobilization. In this work, we perform laboratory experiments to quantify the contribution of capillary trapping to the storage of supercritical CO2in deep saline aquifers.
