Abstract
In 2009, the Danish Energy Agency informed the Geological Survey of Denmark and Greenland (GEUS) that a new legal act (Lov om fordring/Forældelsesloven) would become effective in 2011. The new act introduced a limitation period of three years on the government’s right to request data from licensees’ oil and gas activities in Denmark (www.retsinformation.dk 2007), and it became the catalyst for a major change in the standard procedure for licensees’ submission of seismic data related to exploration activities to GEUS. A consequence of the new legal act was that the Danish authorities would have to request data from the licensee (following the Consolidated Act of the Use of the Subsoil) from the licensee no later than three years after their generation or publication; otherwise the authorities would have no legal right to the data. It was emphasised by the Danish Energy Agency that GEUS would have to submit all requests for outstanding data to the licensees no later than 1 January 2011.

A search in GEUS database showed that field data had been received from only a small percentage of existing 2D and 3D surveys (Fig. 1)
Summary
GEUS and its Danish predecessor the Geological Survey of Denmark (DGU) have systematically collected and stored geological data from Denmark for more than a 100 years. Until the beginning of the 1980s data submitted to DGU from oil and gas activities were stored in the Well Data Archive. For many years only few companies searched for oil in the Danish sector. In 1984 the first competitive licensing round resulted in an increased search for oil, and the submission of data to DGU increased (Fig. 2, extracted from GEUS’ database). Until the 1990s, most of the seismic field data submitted to DGU came from relinquished or expired licences. The authorities have always been able to request copies of the seismic field data this was not listed as a mandatory requirement until 2002 (Danish Energy Agency 2002)
