The data is organized into study areas, giving overview information. A study area contains one or more measurement points, which in turn is (1) a borehole or (2) miniloggers measuring near-surface temperature outside boreholes. Temperature data in boreholes may be temperature series with time (monitoring) or temperature with depth (logs). Near-surface temperature data is temperature series with time only. The database may also hold photographs of study areas (overview) or measurement points (detail).

The database contains information on deep drilling, carried out under a permit, cf. the Subsoil Act, as well as geophysics (especially seismic), licenses and reports. These are exploration, estimation, delineation and production drillings concerning oil/gas, geothermal energy, gas storage and salt, as well as scientific drillings. The dataset contains technical, administrative and geological information from the drillings and about geophysical measurements in the drillings.
