Maersk Oil is the largest oil operator in Denmark. Its biggest partnership is the Danish Underground Consortium (DUC) where 85% of the oil and 97% of the gas export in the country stems from. This adds an important contribution to Denmark’s economy, energy supply and employment.


Maersk Oil produce a mixture of oil and gas oil from 15 fields in Denmark.

The oil and gas reservoirs in the Danish North Sea are characterised by high-porosity, low-permeability chalk.

Production started from the new unmanned platform Tyra Southeast-B, safely, on time and on budget in 2015. The platform is expected to add reserves of 50 million barrels of oil equivalent (BOE) over the next 30 years to Danish production.


First oil production from the Dan Field began in 1972. Since then, 14 other fields have been brought on stream: Gorm, Skjold, Tyra, Rolf, Kraka, Dagmar, Regnar, Valdemar, Svend, Roar, Harald, Lulita, Halfdan and Halfdan Northeast. A third-party field, Trym, in the Norwegian North Sea, has been tied-in to Harald’s infrastructure.

The production peaked in 2005 and has since been on a natural decline. In 2014, Maersk Oil operated a production of 140,000 barrels of oil per day and 370 million standard cubic feet of gas per day.
