Data from 2D and 3D seismic surveys and deep wells are now freely accessible on new subsurface portal

Published 06-10-2023

The Geological Survey for Denmark and Greenland (GEUS) has just launched a new online portal where data from 2D and 3D seismic surveys, as well as data from deep exploration and appraisal wells in Denmark, are now freely available.

In the new portal, released data can now be downloaded for free (though there will still be a handling fee for field data). This makes the enormous amounts of data that have been collected in connection with exploration for oil and gas in Denmark freely accessible for studies of the Danish subsurface. These data will have significant value, for example, in the planning of geothermal facilities or energy islands, carbon capture and storage (CCS), as well as in connection with Power-to-X technologies (PtX) and other purposes related to the green transition.

The portal provides a comprehensive overview of all data reported to the authorities since exploration activities began in the 1970s. Since 2022, GEUS has been working to make as much of these data as possible freely accessible. Currently, all data from all deep exploration and appraisal wells as well as all processed data from 3D seismic surveys can be downloaded for free. The same applies to a significant portion of the processed 2D seismic data collected on land and partially in the inner Danish waters. GEUS is still working on making the extensive amounts of processed 2D seismic data collected in the North Sea, the inner Danish waters, and around Bornholm in the Baltic Sea accessible. The primary focus, for the time being, will be on areas where data from more recent 3D seismic surveys are not available.

GEUS's webshop for purchasing subsurface data (Frisbee) will be discontinued and will no longer be accessible as of October 2023.
