The first oil discovery in the entire North Sea was made by DUC in 1966 in the field later named the Kraka Field.

In July 1972, oil production commenced from the Dan Field, 200 kilometres (120 miles) west of the Danish coast. The Dan Field was the first oil field in the entire North Sea with production from permanent facilities. Since then many more oil and gas fields have been brought on production in the A.P. Møller - Mærsk concession area.
