CHEMKIN
Real-time observation of the chemical and kinetic behavior of carbon dioxide during geological sequestration
The collaborative project, CHEMKIN, aims to develop and apply new geochemical monitoring tools for the real time and in-situ observation of CO2 and additional physical parameters during geological sequestration. CHEMKIN is closely associated to the CO2SINK project. The CO2SINK consortium selected a test site in the vicinity of the town of Ketzin about 20 km NW of Berlin and plans
(1) the drilling of one injection hole and two observation holes in the immediate vicinity (50 - 150 m),
(2) the massive injection of CO2 into a 600 - 800 m deep saline aquifer (Schilfsandstein),
(3) an intensive monitoring of the fate of the injected CO2 using mainly geophysical monitoring techniques.
One topic, among many other open scientific questions, which however has not been considered in CO2SINK, is the geochemical real-time observation at depth of the migration of CO2 within the reservoir and the rate at which CO2 dissolves in saline aquifers. Therefore, the main objective of CHEMKIN is the development of new, innovative sensor concepts and down hole measuring methods and the practical demonstration of the various benefits of a permanent geochemical monitoring system. In addition to geophysical measurements, the geochemical real time observation at depth represents the sole method to gain direct and continuous information. The proposed studies will provide critical analyses and samples and will contribute essential guidance for technical decisions. Other commercially viable technologies are not currently available.
