In this light, the Faroe Islands have pledged to drastically reduce their anthropogenic release of carbon dioxide to the atmosphere, but have not succeeded so far. An efficient way to reach the goal of zero-emission of CO2 is through Carbon Capture and Storage (CCS), which is a technique that countries around us already have invested heavily in. Studies from Iceland, have recently shown promising results of storing CO2 in basaltic rock. This is the same rock type that is covering 99.5% of the Faroese sector, but the potential of CCS in the Faroe Islands have not yet been investigated. The main aim of this study is to build the knowledge basis required to evaluate CCS in the Faroe Islands Basaltic Group (FIBG). This will be done by fracture mapping, both at a regional scale, and detailed mapping at a selected site. Following this, a scientific well will be drilled at the study site, and detailed analyses of fractures, porosity and permeability will be done on the drilled section. Lastly, flow simulations of the study site will be made, with the overreaching aim to test the reservoir quality of the FIBG. The knowledge obtained by this project also has relevance for other areas, e.g. it can serve as a unique analogue to the Faroese offshore areas as well as offshore Norway. The ultimate goal of this project is thus societal, namely to provide local policymakers with a sound scientific basis for decisions about future investments in CCS in the Faroe Islands. Final With the aim of evaluating the Faroese flood basalts as a storage reservoir for CO2, this project has collected, integrated and analysed data across various scales. The work has been divided into three studies, where the first study investigates the stratigraphic and structural framework of the Faroe Islands Basalt Group, the second investigates the impact of fractures on basaltic reservoirs and the last tests the absolute injectivity of basalt sequences. The main findings of these studies are (I) that multiscale integration of geological and geophysical data is critical when mapping heterogeneous flood basalts, (II) fractures have a significant impact on permeability and anisotropy of basaltic reservoirs, (III) vesicular basalts exhibit higher permeability when tested at the reservoir scale than at the cm-scale. Overall, these results improve understanding of fluid flow in the Faroese subsurface and in other locations where flood basalts are considered reservoirs. These results therefore provide a solid basis for policymakers and industry to inform future decisions on mitigating CO2 emissions through geological carbon storage.
