Well Data Archive

The Well Data Archive was established as a result of the Water Supply Act of 1926 with the purpose of registering and preserving data on groundwater and geological conditions.
The Archive also holds data on wells from before 1926. The wells are registered in the national database Jupiter, which contains data from more than 270.000 shallow wells. Data for deeper wells, and oil and gas related data are stored in the Subsurface Archive.

Wells are established in Jupiter by getting a well number (DGU number) assigned from the well location. The Well Data Archive is responsible for allocating DGU numbers. Data in Jupiter are publicly available and may be accessed through Interactive map, Google Earth KML or Jupiter søgeformular ( Danish version only).

In Jupiter the Well Data archive records:

  • Administrative data: driller, drilling site address, coordinates and elevation, date(s) of drilling, cadastral number, municipality, requisitioner
  • Technical data: borehole dimensions, casing and screen data, grout, gravel pack
  • Lithological data: drillers description of the layers
  • Water data: waterlevel, pumping, recovery
  • Plug and abandonment data
  • Well location
  • Updates and corrections
Apart from the well data which the Well Data Archive registers and maintains, Jupiter contains numerous other data. The Geological Well Sample Laboratory registers descriptions of more than 13,000 soil samples a year in Jupiter. The municipalities maintains data from more than 35,000 water reclamation plants and on a daily base laboratories reports chemical analysis of ground- and drinking water from wells and plants nationwide.
