Who operates the Oseberg field?

Oseberg is operated by Equinor Energy AS, in partnership with Petoro AS, TotalEnergies EP Norge AS, ConocoPhillips Skandinavia AS.

How much does Oseberg produce?

113,562 barrels of oil equivalent per day as of May 2026 — 2.7% of Norwegian Continental Shelf output, ranking 9 of 94 producing fields.

When did Oseberg start producing?

First production was reported in 1986, 7 years after discovery well 30/6-1 proved the field in 1979.

What is the Norwegian Continental Shelf?

The Norwegian Continental Shelf (NCS) is the seabed area where Norway holds sovereign rights over petroleum resources, covering the North Sea, the Norwegian Sea and the Barents Sea. It holds roughly 90 producing fields, and its output is the largest single source of Norway's export income.

What does NCS Live show?

Every in-service surface installation and subsea structure on the shelf, the offshore pipeline network, field outlines and seabed relief, with live vessel traffic and offshore helicopter flights on top of them. Optional layers add seismic survey activity, cold-water coral, wind and wave forecasts, and a counter for the value each field is producing today.

Where does the data come from?

Infrastructure, fields and production come from the Norwegian Offshore Directorate (Sokkeldirektoratet) FactPages under the NLOD licence. Vessel positions are AIS from BarentsWatch and Kystverket. Helicopter movements are derived from Avinor flight data. Coral observations come from the Institute of Marine Research and MAREANO, and export prices from Statistics Norway (SSB).

Is the vessel traffic real time?

Yes. Tankers and offshore support vessels are drawn from live AIS positions and refreshed continuously, with speed, course and self-reported destination. Helicopter positions are dead-reckoned estimates between known departures and arrivals, not surveillance.

Are the pipeline flows measured?

No. Pipeline thickness and the travelling flow animation are estimates, derived by accumulating monthly field production through the pipeline network. They are not metered throughput, and thickness is not pipe diameter.

Can I see how the shelf was built out?

Yes. The time machine replays the shelf from 1971, the year Ekofisk started producing, to today. Installations and pipelines appear in the year they entered service, with total production and the number of producing fields for each year.

Is NCS Live free to use?

Yes, free and with no account. It is a public visualisation of open data, built and designed by Smpl and Melvær&Co in Norway.

What it produces

In May 2026 the field delivered 113,562 barrels of oil equivalent a day, classified by the directorate as oil/gas — roughly 14% oil and 81% gas by energy content. Output has moved down 18.1% over the past twelve months, and the directorate's profile for the field is late life. The field's best year was 1994, averaging 503,401 boe/d — today it runs at 23% of that.

Since 1986, Oseberg has produced roughly 3,286 million barrels of oil equivalent in total. The directorate's estimate of recoverable resources is 3,489 million boe, of which about 94% has now been recovered; 485 million boe remained as of 31.12.2025.

The story of Oseberg

Oseberg — named, like many Norwegian fields, after a national treasure, the Oseberg Viking ship — reported its first volumes in 1986 and reached full field production once the Oseberg Field Centre was complete, growing into a hub for a whole area of the northern North Sea with its oil piped to the Sture terminal. In 1991 it received gas from Troll through TOGI, the first subsea gas injection project of its kind.

Discovery and drilling

The field was proven by exploration well 30/6-1 in 1979. The directorate's wellbore register lists 342 wellbores on Oseberg: 36 exploration and 306 development. The deepest reaches 10,007 metres measured depth. Water depth at the field's installations is 101 to 110 metres.

How it reaches market

Oseberg's production leaves the field by pipeline:

Oseberg Oljetransportoil → Sture
Oseberg Gasstransportgas → Heimdal Hrp

The field has run on power from shore — fed from Kollsnes since 2026 — rather than on gas turbines offshore.
