| Ressourcenüberblick | Regarding the use of renewable energy and the reduction of greenhouse-gas emissions, the geological storage of fluids is of particular interest. Therefore, reservoir and barrier formations in the German North Sea come into focus. Due to the widespread distribution of storage and barrier rocks at suitable depths and in combination with a relatively low tectonic overprint, the West Schleswig Block region in the German North Sea shows a high prospectivity for CO2 storage. By means of this high-resolution 2D reflection seismic survey, we want to investigate the potential impairment of geological barriers at the top of geological storage formations (i.e. claystones/mudstones and salt of the Upper Buntsandstein, mudstone dominated formations of the Lower Cretaceous and of the Tertiary). The seismic acquisition setup with a 2400 m active streamer cable with 384 channels will allow a precise image of near-surface structures, such as Quaternary channels, seismic pipe structures, chimneys, polygonal fault systems and crestal faults. In the time period between Nov. 13th and Nov. 24th we acquired 32 lines 2D seismic reflection data (about 1500 km in total) in combination with gravity data, multibeam data and sediment echosounder data. The seismic data resolve the sediments from the seafloor down to the base of the Zechstein. With the acquired data, the sediments of the Mesozoic and Cenozoic up to the seafloor (2-3 seconds of twoway-traveltime) will be imaged in high-resolution for the first time. The imaged fault systems will be investigated regarding their ability to build seal bypass systems. In addition, we acquired seismic data across the Figge Maar blowout crater and we intend to compare these data with the seismic data from the West Schleswig Block. |
