Who operates the Blane field?

Blane is operated by Repsol Norge AS, in partnership with DNO North Sea (UK) Limited, Bridge Petroleum 3 Limited, DNO North Sea (ROGB) Limited.

How much does Blane produce?

180 barrels of oil equivalent per day as of May 2026 — 0.0% of Norwegian Continental Shelf output, ranking 92 of 94 producing fields.

When did Blane start producing?

First production was reported in 2007, 18 years after discovery well 1/2-1 proved the field in 1989.

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 180 barrels of oil equivalent a day, classified by the directorate as oil — almost entirely oil. Output has moved down 12.2% over the past twelve months, and the directorate's profile for the field is late life. The field's best year was 2008, averaging 2,497 boe/d — today it runs at 7% of that.

Since 2007, Blane has produced roughly 5 million barrels of oil equivalent in total. The directorate's estimate of recoverable resources is 11 million boe, of which about 49% has now been recovered; 0 million boe remained as of 31.12.2025.
