Maersk Oil is working hard at optimising operations in its mature fields in the Danish North Sea to offset declining output. This includes looking into carbon dioxide-based Enhanced Oil Recovery (EOR).

At the same time, new field developments, such as one at the Halfdan field, as well as exploration and development activities such as at the Luke and Elly fields discoveries, are ongoing.

Maersk Oil produced 225,000 barrels of oil a day and 1,000 million cubic feet of saleable gas a day from the primarily tight chalk fields operated by Maersk Oil. Oil production levels are accomplished through extensive water flooding by injecting 800,000 barrels of water a day into reservoirs.

Maersk Oil (39%), as part of the DUC consortium (Shell 46%, Chevron 15%), operates the main 1,754 sq. kms concession granted to A.P. Moller - Maersk in 1962. In addition to this concession, Maersk Oil (31.2%) is conducting exploration activities in Licence 9/95 Maja and 9/06 Gita with PA Resources (26.8%), DONG E&P (20%), Altines Oil (12%) and Danoil (10%). Maersk Oil (36.7%) also operates Licence 8/06 with Shell (43.3%) and The Danish North Sea Fund (20%).
