The Reactions and flow of CO₂ fluid in compositionally immature sandstones explores how the composition of feldspar and clay contained in sandstone reservoirs may react with injected carbon dioxide. By drawing on case studies from the north Atlantic region, an improved understanding of the drivers for feldspar and clay compositional variations is expected, which may more widely inform the suitability of reservoirs earmarked for carbon capture and storage projects.

This project will utilise CASP’s new SEM facility, setup to facilitate this and other research projects addressing the energy transition. Further projects will be announced in due course.
