At the Ketzin pilot site (Germany), a permanent downhole electrode array is accompanying the geological CO2 storage operation from June 2007 until December 2016. Electrical resistivity tomography (ERT) results provide images about relevant operational stages of the storage reservoir. The presented geoelectrical downhole system displays a very promising long-term behavior, and its technical effort and cost has been amortized by its continuous application during the complete injection history. The experiences drawn from the Ketzin site yield strong arguments for the application of the ERT method as part of a multi-disciplinary monitoring concept.
