Maersk Oil is a Danish oil and gas company owned by the A. P. Moller-Maersk Group. The company was established in 1962 when Maersk Group was awarded a concession for oil and gas exploration and production in the Danish sector of the North Sea.
Maersk Oil entered into an Exploration and Production Sharing Agreement (EPSA) with Qatar Petroleum (QP) in 1992. The EPSA included an oil-bearing reservoir – the Al Shaheen field – which had been deemed uneconomic by others as its reservoirs were extremely tight and stretched across vast distances. Despite this complexity, Maersk Oil produced first oil just two years later and is now producing over one third of Qatar’s daily oil production, some 300,000 barrels of oil per day.
