Abstract

The assessment of expected long-term CO2-induced mineral alterations of reservoir and cap rock is crucial to ensure the long-term stability of the storage project, and to evaluate the potential carbon trapping provided by mineralization. In the first european on-shore pilot site at Ketzin, nearby Potsdam, Germany, about 60,000 t of CO2 were injected (as of February, 2012) in a saline aquifer in a Triassic sandstone at about 650 m depth. A rich set of analyses of pristine formation fluids [1] as well as mineralogical and geochemical composition of the reservoir rock [2] made possible a precise parametrization of the reference geochemical model.
