Progress Report on the First European on-shore CO_2 Storage Site at Ketzin (Germany) - Second Year of Injection

摘要

The pilot study at the Ketzin site close to Berlin (Germany) aims at in-situ testing of geological storage of CO_2 in a saline aquifer. Following site characterization and the drilling of one injection well and two observation wells, the in-situ field laboratory has been fully in use since CO_2 injection started in June 2008. After two years of operation, about 36,000 tons of CO_2 have been injected. This paper presents the key results from the second year of injection and the interdisciplinary monitoring concept in the frame of the European project CO_2SINK (CO_2 Storage by Injection into a Natural Saline Aquifer at Ketzin) and accompanying projects.
