CO2 underground storage costs as experienced at Sleipner and Weyburn

Publisher Summary Two major industrial undertakings—at Sleipner and Weyburn—show the technical feasibility of storing CO2 in underground geological formations in large volumes. Their scale makes the investment and operational costs they have experienced of interest to a wider audience. The purpose of this chapter is to highlight the extra costs associated with the CO2 injection for storage purposes only. The design and operational considerations for both the projects are summarized. In both projects the extra equipment for the CO2 injection/storage was part of a large industrial development project, so the costs reported herein could not be very detailed. The reported costs for the two projects are very difficult to compare since the situations were so different.
