The studies build on the seismic surveys that the Geological Survey of Denmark and Greenland (GEUS) carried out in the subsurface in the area between Hobro and Randers. They provided an initial assessment of the geological conditions and concluded that the area could potentially be suitable for CO2 storage. The upcoming seismic surveys are even more detailed and thorough and will provide an even better picture that can confirm or nuance this assessment.
What are seismic surveys?
Seismic surveys map the subsurface using sound waves. When doing so, these sound waves are reflected back to the surface where they are captured and analysed. When the sound waves are analysed, it becomes possible to map the different geological layers in the subsurface to identify the potential locations where CO2 can be safely stored.
For CCS projects that aim to store CO2, it is crucial that the storage sites are safe and stable, which is why the results of the seismic surveys are crucial for the location of the storage areas. In addition, the data collected will be used in the comprehensive monitoring of the subsurface that will be established if we end up being able to establish a storage facility.
