Tu gme 07: Influence of poromechanical and thermal properties of the caprock on the safety of co2 storage

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

Geologic carbon sequestration is a promising option to reduce carbon dioxide emibions to the atmosphere and mitigate climate change. The injected CO2 will reach the storage formation at a colder temperature than that of the host rock. This cold CO2 will cool down the caprock by conduction, which will induce thermal streb reduction and prebure changes that will affect caprock stability. We analyzed thermoporomechanical response of Swib shale and found that the effective streb changes induced by cooling do not have, in general, the potential to jeopardize the caprock sealing capacity.
