CO2 storage potential of the Jurassic within the German Central Graben
Within the framework of the GEOSTOR Project, the CO2 storage potential of the Jurassic succession in the German Central Graben was analysed. Twelve potential trap structures were initially mapped along the base of the Kimmeridge Clay Formation, which serves as the primary seal for potential reservoir sandstones within the Central Graben Subgroup. The Kimmeridge Clay Formation is generally continuously distributed across the German Central Graben, with only localized penetrations by rising salt diapirs. In contrast, the Central Graben Subgroup, serving as a potential reservoir unit, exhibits an uneven distribution across the area, limiting the presence and continuity of reservoir rocks within each trap structure. To further delineate the spatial extent of the mapped reservoir structures, the base of the Central Graben Subgroup was used as an additional reference layer. Due to the intermittent nature of Jurassic sandstones within the Central Graben Subgroup, a subsequent analysis classified each structure based on borehole data to confirm the presence of reservoir sands. Structures were categorized as ‘proven,’ ‘not present,’ or ‘uncertain’ depending on sandstone availability and continuity within the trap. All mapped reservoir structures are buried at depths ranging from 2225 to 3043 meters (apex depth) and are considered closed systems, situated within a complex structural network of salt diapirs, faults, and pinch-outs. Capacity calculations were conducted following the method outlined by Fuhrmann et al. (2024), and the horizons used for mapping are based on the work of Müller et al. (2023) and Thöle et al. (2021).

CO2 storage potential of the Middle Buntsandstein Subgroup - EEZ of the German North Sea
The CO2 storage potential of the Middle Buntsandstein Subgroup within the Exclusive Economic Zone (EEZ) of the German North Sea was analysed within the framework of the GEOSTOR-Project. A total of 71 potential storage sites were mapped based on existing 3D models, seismic and well data. Static CO2 capacities were calculated for each structure using Monte Carlo simulations with 10,000 iterations to account for uncertainties. All potential reservoirs were evaluated based on their static capacity, burial depth, top seal integrity and trap type. Analysis identified 38 potential storage sites with burial depths between 800 m and 4500 m, reservoir capacities (P50) above 5 Mt CO2 and suitable sealing units. The best storage conditions are expected on the West Schleswig Block where salt-controlled anticlines with moderate burial depths, large reservoir capacities and limited lateral flow barriers are the dominant trap types. Relatively poor storage conditions can be anticipated for small (P50 <5 Mt CO2), deeply buried (> 4500 m) and structurally complex potential storage sites in the Horn and Central Graben.

CO2 storage potentials German North Sea (WMS)

Storage of CO2 in deep geological formations is one possibility of reducing CO2 emissions from industry that are difficult to avoid. High-quality geological models and capacity estimates are crucial for the successful planning and implementation of safe storage projects. This study analyses the storage potential of the Middle Buntssandstein (Lower Triassic) and Lower to Middle Jurassic within the Exclusive Economic Zone (EEZ) of the German North Sea. Link https://geostor.cdrmare.de/ Die Speicherung von CO2 in tief versenkten geologischen Formationen stellt eine Möglichkeit dar, um schwer vermeidbare CO2-Emissionen aus der Industrie zu mindern. Hochwertige geologische Modelle und Kapazitätsabschätzungen sind entscheidend für die erfolgreiche Planung und Umsetzung sicherer Speicherprojekte. Diese Studie untersucht das Speicherpotenzial des Mittleren Buntsandstein und Unteren bis Mittleren Jura innerhalb der Ausschließlichen Wirtschaftszone (AWZ) der deutschen Nordsee.
