CO2 storage, CO2 storage and clean coal/shale technologies

The research is focused on developing innovative methodologies for monitoring the porous reservoir where supercritical CO2 is stored. A dedicated laboratory facility is being developed where downscaled electrical and seismic measurements are performed at elevated pressure and temperature conditions mimicking underground CO2 storage reservoirs. The dynamic changes in the reservoir are predicted using newly developed approaches.

Most of our CO₂-storage and monitoring research takes place within the CATO2 program. In five work-packages the department is active, i.e.:

1. Geomechanical effects of CO₂ storage on reservoir-caprock-fault systems.
2. The physical-chemistry of carbonated water flooding for enhanced oil- and gas-recovery (EOR/EGR).
3. Geothermal energy production combined with CO₂-injection  in the Delft sand reservoir.
4. Studies for permanent seismic/EM monitoring and interpretation of the signals.
5. A geophysical experimental set-up to measure complex electrical impedance and seismic responce of porous reservoir and cap-rocks with gas-water mixtures, as a function of pressure, temperature and water saturation.
