Nordsøfonden is partner in DUC with a 20 % share.


The Danish Underground Consortium (DUC) is a joint venture between Total E&P Danmark A/S (31.2 %), Noreco (36.8 %), Total Denmark ASW, Filial af Total Denmark ASW Inc. (12 %) and Nordsøfonden (20 %) cooperating to recover oil from the Sole Concession holder’s area of the Danish North Sea.

DUC today accounts for by far the majority of the Danish oil and gas produced and is the owner of the key points of the infrastructure of all activity in the Danish sector of the North Sea. The Sole Concession covers 1,635.7 km² of the Danish shelf.


History of DUC

DUC was established in 1962, when A.P. Møller (now called A.P. Møller-Mærsk) was awarded the Sole Concession, in order to assist the company in producing oil in the best possible way.

Originally, the DUC consisted of A.P. Møller, Shell and Gulf, the latter acting as the operator. Within a few years Texaco and Chevron, too, joined the consortium. In 1974 Gulf withdrew from the cooperation, and Maersk took over as the operator. In 1987 Chevron withdrew, but in 2001 they re-joined DUC via their merger with Texaco.

The construction of the consortium was changed in 2012, when Nordsøfonden joined the DUC as an active 20 % state-owned partner.

In 2018, Total aquired all of A.P. Møllers- Mærsk's oil and gas activities, including the Sole Concession area and the role as operator in DUC. In 2019 Total acquired Chevron's share in DUC, while Noreco acquired Shells share.
