Two types of geological structures are being studied within task 1.1:
- Deep (saline) aquifers for the storage of gas (e.g. CO2) and the extraction of heat
- Fractured reservoirs in deep crystalline and sedimentary basements for the generation of electricity or the extraction of heat
The research involves a mix of experimental and modelling approaches, such as the analysis of drill cores, seismic surveys and novel geophysical techniques in order to characterize reservoirs and construct 3D models of the underground.
