OKEA ASA said on Oct. 3 its Hasselmus discovery in the Norwegian Sea started producing to the Draugen platform on Oct. 1.

The Hasselmus subsea tieback is expected to add 4,400 boe/d at plateau, OKEA said.

The project, which is OKEA’s first operated project, is expected to recover approximately 1.65 Bcm of natural gas and will restart export of associated gas and NGL from Draugen in PL 093.

“The project is important for the long-term development of Draugen and demonstrates our ability to extend the life of mature fields,” OKEA CEO Svein J. Liknes said in a press release.

The Hasselmus gas discovery is located on the western edge of the Trøndelag platform in the Norwegian Sea, 7 km northwest of the Draugen platform. Shell drilled the 6407/9-9 T2 well on the Hasselmus structure in 1999, and it encountered a 16-m gas column and a 6.8-m oil column in high quality sands at a depth of 1,700 m.

OKEA operates the Draugen license with 44.56% interest on behalf of partners Petoro AS with 47.88% interest and M Vest Energy AS with 7.56% interest.
