Danish subsurface data will be freely accessible

Published 29-06-2022

Information about the Danish subsurface is crucial when it comes to the green transition and large construction projects, and therefore GEUS has decided to make data from the deep subsurface in Denmark free for all. First, the well data, and later the seismic data.

As the national geological data centre of Denmark, The Geological Survey of Denmark and Greenland (GEUS) hold an abundance of information about the Danish subsurface via data from wells and seismic surveys that have been carried out in connection with oil, gas and geothermal energy exploration etc.

The data were collated in the North Sea and inner Danish waters and on land, e.g. Stenlille on Zealand and Feldsted and Tønder in South Jutland.

”These data are needed for projects involving the subsurface. Amongst other things, there are more and more initiatives related to the green transition that require knowledge about the subsurface, e.g. windmills, energy islands, geothermal energy, CO2 storage and climate adaptation,” says Mikael Pedersen, Head of Department for the Geological Data Centre at GEUS.

Today, all GEUS’ data on the upper part of the Danish subsurface are free, but in the future, GEUS will also make data about the deep Danish subsurface freely accessible for all, e.g. data from wells and seismic surveys.

Get data from Frisbee

Up until now, only the completion reports from Danish wells have been free to download but from 1 July 2022, all released well data such as reports, logs and photos of cores can be downloaded free of charge. That means that all these data are now included in GEUS’ well data packages. Data from 2D and 3D seismic surveys will be made free in the next two years. Everything can be found at GEUS’ webshop for subsurface data, Frisbee.

The data have been collated by the companies that have drilled the wells and carried out the seismic surveys. A copy of all tests and other data from surveys in the Danish subsurface must be submitted to GEUS as soon as they are available, but some data are not released for 5 or 10 years. The information is stored in GEUS’ national subsurface data base, SAMBA.
