ABSTRACT

At the Ketzin site close to Berlin (Germany), a pilot

study aims at in-situ testing of geological storage of

CO

in a saline aquifer. Following geological site

characterization and drilling of one injection well

and two observation wells, the in-situ field laborato-

ry is fully in use since the CO

injection started in

June 2008 (Schilling et al. 2009). Work at the pilot

site covers all aspects of a storage site to be per-

formed in the future (Fig. 1).
