Zusammenfassung:
The comprehensive interpretation of different data types becomes increasingly challenging, even more if the integration should be carried out in a quantitative manner. A hydrogeophysical reservoir model is set up that links the single phase hydraulics, multiphase behaviour and geoelectrical properties of a CO2 storage reservoir. The model is embedded into a fully coupled inversion framework that explicitly honours the physical processes underlying the different types of measurement data. The calibrated model provides a comprehensive representation of all data, with an excellent accuracy for hydraulic and gas pressure data and a satisfactory accuracy of arrival times and geoelectrical data. The permeability is within reasonable bounds but the spatial distribution shows several indications for overfitting. The model reproduces the main migration direction of the plume.
