The structures decided for maturation by the authorities, are some of the largest structures onshore Zealand, Jutland and Lolland and in the eastern North Sea (Fig. 1.1). The onshore structures include the Havnsø, Gassum, Thorning, and Rødby structures, and in addition the small Stenlille structure as a demonstration (pilot) site. The offshore structures include the Inez, Lisa and Jammerbugt structures. A GEUS Report is produced for each of the structures to mature the structure as part of the CCS2022–2024 project towards potential geological storage of CO2.
The intension with the project reporting for each structure is to provide a knowledge-based maturation with improved database and solid basic descriptions to improve the understanding of the formation, composition, and geometry of the structure. It includes a description overview and mapping of the reservoir and seal formations, the largest faults, the lowermost closure (spill-point) and structural top point of the reservoir, estimations of the overall closure area and gross-rock volume. In addition, the database will be updated, where needed with rescanning of some of the old seismic data, and acquisition of new seismic data in a grid over the structures, except for the Inez and Lisa structures, which have sufficient seismic data for this initial maturation.
The reports will provide an updated overview of the database, geology, and seismic interpretation for all with interests in the structures and will become public available. Each reporting is a first step toward geological maturation and site characterization of the structures. A full technical evaluation of the structures to cover all site characterization aspects related to CO2 storage including risk assessment is recommended for the further process.
