Natural analogue of carbon dioxide geological storage

A large volume of carbon dioxide emissions from burning fossil fuels are heating up our planet. Carbon capture and storage (CCS) has been identified as a feasible technology to reduce emissions whilst permitting the continued use of fossil fuels. Carbon dioxide can be captured from point sources and injected into geological formations. Injected gas must remain isolated from the atmosphere for tens of thousands of years or longer, hence the need to predict long-term performance of geological storage. Natural CO2-rich sites provide excellent analogues on such a timescale. This book examines Miller field in the North Sea, which has naturally contained high carbon dioxide for millions of years. It reports rich datasets obtained using multiple techniques, including XRD, SEM, Raman microspectroscopy, fluid inclusion thermometry, stable isotopes, etc., which help to establish the geological history of carbon dioxide and geochemical interactions. The study should improve our understanding of CCS-related diagenesis and geochemistry. It should be useful to researchers and regulators involved in CCS activities and geologists generally interested in petrology, diagenesis, and geochemistry.
