Start-up of production from the Bøyla field

Start-up of production from the Bøyla field

Det norske oljeselskap ASA (Det norske) and partners of the PL 340 license

announce start-up of production from the Bøyla field. With that, Bøyla is the

fourth field in production in the Alvheim area, adding 15 million barrels of oil

equivalents to Det norske's reserves.

Total investments in the development of the Bøyla field amount to approximately

NOK 5 billion. Recoverable reserves from the field are estimated at

approximately 23 million barrels of oil equivalents, whereof Det norske's share

is 15 million barrels of oil equivalents.

The development solution is a subsea installation consisting of two horizontal

production wells and one water injection well. The expected maximum production

rate is in excess of 20 000 barrels of oil equivalents per day when both wells

are in production.

"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", says the Chief Executive Officer of Det norske, Karl

Johnny Hersvik.

The Bøyla field is tied back to the Alvheim FPSO's existing infrastructure via a

28-kilometre pipeline. The processing capacity of the Alvheim FPSO is

approximately 150 000 barrels per day, and the vessel has been subjected to

minor modification in order to receive and process volumes from the Bøyla field.

The Bøyla field is located in block 24/9 in the northern part of the North Sea.

The licence was awarded in the APA 2004 licensing round, and the first discovery

was made in 2009 (the Marihøne prospect). The discovery was confirmed by two

appraisal wells the same year. The plan for development and operation was

submitted to and approved by the Norwegian authorities in 2012. Construction of

the subsea structures on the Bøyla field commenced in 2013, and the construction

work has been carried out mainly by Norwegian contractors.

Det norske is the operator for the Bøyla field and holds a 65% interest.

Partners are Core Energy AS with 20% interest and Lundin Norway AS, holding the

remaining 15% interest.
