Oil production began from Statoil's Siri platform off Denmark on 1 March, a little more than three years after the field was found.
The development solution proposed by the Siri licensees was approved by the Danish Energy Agency about 18 months ago, and the field is the 14th to come on stream in Denmark's North Sea sector.
Also ranked as the first Danish field to begin production outside the Central Graben area, Siri has been developed with a jack-up platform supporting processing facilities and the living quarters.
This unit stands on a seabed storage tank in steel with a capacity of 314,500 barrels. Oil will be shipped from the field in shuttle tankers.
A single well is initially on stream, with Noble George Sauvageau continuing to drill further production and injection wells under a contract awarded last May.
Plateau production from the field will total close to 50,000 barrels per day.
The Siri licensees have contracted Statoil's Kalundborg refinery near Copenhagen to provide platform operation and maintenance as well as engineering support on land. About 20 people will normally staff the platform.
