A technical basis for carbon dioxide storage
Cal Cooper on behalf of the CO2
This paper is the synopsis of a larger work completed under the auspices of the CO2 Capture Project, an international effort funded by eight of the world’s leading energy companies. It seeks to explain the rationale for the geological storage of carbon dioxide (CO2) based on insights from the practical experience of the oil and gas industry. It considers the key technical applications that will make storage possible, and the subsurface management processes that will provide confidence to all stakeholders that storage is effective. Four broad areas are described including, the selection and characterization of sites for CO2 storage; issues of well integrity and well construction; the requirements of monitoring programs for appropriate data collection and risk management. Finally, issues arising from storage operations and the eventual closure and decommissioning of CO2 storage sites are addressed.
