Oil production has commenced at the Bøyla field, located on PL340 in the Norwegian sector of the North Sea.
Det norske operates the Bøyla field with a 65% interest, while Core Energy and Lundin Norway own 20% and 15% stakes, respectively.
The Bøyla field is tied back to the Alvheim floating production, storage and offloading (FPSO) unit’s existing infrastructure via a 28km pipeline.
The Bøyla field is estimated to contain gross reserves of 23 million barrels of oil equivalent and is expected to produce at a gross peak rate of around 20,000 barrels of oil equivalent per day (boepd) after completion of the second production well.
Drilling operations on the second production well were suspended in late-2014.
The Transocean Winner semi-submersible rig will return to complete the well-drilling in the second quarter of this year with start-up expected by mid-2015.
Det norske CEO Karl Johnny Hersvik said: "Bøyla is the fourth producing field tied back to Alvheim FPSO and the volumes added from this field are important in maintaining production from the Alvheim area at a high level."
As well as the Alvheim and Bøyla fields, the Volund and Vilje fields provide production to the Alvheim FPSO, which has a processing capacity of around 150,000 barrels per day.
