Producing assets

Gudrun is an oil and gas field located in PL 025, about 55 km north of the Sleipner installations. It is developed with a traditional steel platform resting on the seabed, with capacity for partial treatment of hydrocarbons before transported via pipeline to Sleipner A. From there, gas is exported to European markets, and oil is routed together with Sleipner condensate to Kårstø for shipping.

The reservoir is high pressure and high temperature, requiring advanced technology, and draws on experience from Kvitebjørn and Kristin developments.

Latest update: A third infill drilling campaign was approved, with two new wells planned for 2026.

Gullfaks is a mature field located in the Tampen area, developed with three integrated processing, drilling, and accommodation facilities: Gullfaks A, B, and C. These concrete-based platforms support production from several satellite fields including Tordis, Vigdis, Snorre, Visund, and Brime.

The field has undergone multiple development phases since its discovery in 1978, including enhanced recovery projects and tie-ins.

Sustainability highlight: Gullfaks is one of the first fields globally to receive power from a floating wind farm. The Hywind Tampen wind farm began supplying electricity in 2022/2023, achieving 90,000 tonnes of CO₂ savings in its first year.

Latest update (2024): Nine new wells were delivered and handed over to production.

Edvard Grieg is a high-performing oil and gas field located approximately 180 km west of Stavanger. Developed with a bottom-fixed steel jacket and full processing facilities, the platform has consistently delivered high operational regularity and production efficiency.

The field receives oil and gas from the nearby Ivar Aasen field for final processing and export, and serves as a host platform for several tie-back developments, including Solveig Phase 1 and 2, Troldhaugen, and Symra.

Edvard Grieg operates with renewable electricity from shore via the Utsira High area solution, resulting in very low CO₂ emissions.

 Latest update:

• Infill drilling has extended the Edvard Grieg field life. After a production decline in 2022, a third campaign was approved in 2024 to cut unit costs and unlock reserves. Two new wells were drilled with minimal platform modifications and are now producing. 
• The Solveig Phase 2 subsea tie-back is under construction, with production expected in 2026.
• Tie-ins from Troldhaugen and Symra are also progressing, further strengthening Edvard Grieg’s role as a regional hub.

Aasta Hansteen is the deepest field development on the Norwegian Continental Shelf, located at a depth of 1,300 metres and 300 km west of Sandnessjøen. It features the world’s largest spar platform – a 339-metre-tall floating structure anchored to the seabed – and is the first of its kind in Norway.

The field includes the original Luva, Haklang, and Snefrid Sør discoveries, with Snefrid Nord tied in later. Condensate is stored onboard and offloaded to shuttle tankers, while dry gas is transported via the Polarled pipeline to the Nyhamna terminal for export to the UK and Europe.

Latest update: Aasta Hansteen is currently producing at plateau. It is considered a potential host for nearby discoveries once plateau production ends. The Irpa gas discovery (formerly Asterix) will be tied back to the platform via an 80-km pipeline, with three wells planned.
