DNO Norge, OKEA agree to Brasse fast-track development concept

DNO Norge AS will transfer operatorship of the Brasse discovery in production license (PL) 740 to OKEA ASA and partners will investigate a tieback to nearby Brage field offshore Norway. A final investment decision is expected early next year.

The North Sea project was restarted in early 2023 with a review of a simplified tieback to the Brage platform 13 km north of Brasse. This review has led to approval of a concept selection (DG2) involving a much-reduced topside modification scope on Brage compared to previous considerations of a linkup with a host platform.

Well design has also been simplified to a two-well development targeting recovery of up to 30 MMboe from Brasse (estimated two-thirds oil and one-third natural gas and NGL), with a potential start-up as early as 2026.

In December 2022, OKEA and DNO ASA entered into an agreement for OKEA to become 50% owner of Brasse (OGJ Online, Dec. 29, 2022). Operatorship of Brasse will be transferred to OKEA from DNO on Sept. 1.

OKEA took over as Brage operator last fall and the main commercial terms for the tie-in have been agreed with the Brage joint venture, in which DNO holds a 14.2567% stake (OGJ Online, May 23, 2022).

OKEA also entered into an SPA with M Vest Energy AS (M Vest) to sell 4.4424% working interest in Brasse to further align ownership in the two licenses. The SPA is subject to customary government approvals.
