Abstract

The geochemistry of water-rock interaction in a Hot Dry Rock (HDR) geothermal system has been studied. This report presents a comprehensive summary of the studies done by the collaborating groups: Department of Chemistry - University of Antwerp (Belgium), Laboratoire de Géochimie des Eaux - Université Paris VII (France), British Geological Survey - Keyworth (UK) and Mineralogical Institute - University of Karlsruhe (FRG). The main topics reported are the reaction kinetics and the investigations of the reacted heat exchanger fluids, the reacted minerals/rocks, the precipitation of secondary minerals, the mineral transformations and the dissolution behaviour of the trace elements. Results obtained from this study could be used to predict the long-term effect of operating an HDR system.
