Maersk Oil said production has started from its unmanned platform in the Danish North Sea.
The Tyra Southeast-B platform is expected to add reserves of 50 million barrels of oil equivalent (boe) over the next 30 years.
Drilling of the well first commenced in December 2014 from the Ensco 72 drilling rig.
Maersk said production from this well alone is expected to be around 2,600 boepd.
The plan is to drill a total of 8-12 horizontal wells during 2015-2017 with each well being about six kilometres long.
Maersk Oil chief executive Jakob Thomasen, said: “The Tyra Southeast extension is a great example of how we extract value from the Danish North Sea by combining intricate knowledge, long-term
investments and the right technical capabilities.
“Over the next three decades, the new platform will add both oil and gas to our production. This is an important step in Maersk Oil’s growth journey and it demonstrates that Denmark continues
to be a core area for us.”
The total investment in the Tyra Southeast expansion of DKK 4.5 billion includes the platform with a total weight of 4,700 tonnes, pipelines and drilling of the wells.
The investment is the largest made by Danish Underground Consortium since the approval of the Phase IV development of Halfdan in 2007.
