摘要

Two major industrial undertakings - at Sleipner and Weyburn - show the technical feasibility of storing CO_2 in underground geological formations in large volumes. Their scale makes the investment and operational costs they have experienced of interest to a wider audience. Together they cover a wide set of parameters: Sleipner is offshore in the North Sea -Weyburn is onshore on the plains of Mid-West Canada. Sleipner stores CO_2 in a deep saltwater formation -Weyburn is an Enhanced Oil Recovery project. Sleipner injects by one horizontal injection well -Weyburn uses both horizontal and vertical wells. Sleipner gets the CO_2 from natural gas produced on-the-spot -Weyburn transports CO_2 by a 330 km pipeline from a coal gasifier in the USA. Sleipner has minimal impurities -Weyburn co-injects H_2S; a well-known Canadian procedure. This paper highlights the extra costs associated with the CO_2 injection for storage purposes only. The design and operational considerations for both projects are only summarized, since they have been reported previously. In both projects the extra equipment for the CO_2 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.
