Transport according to Sodir's field description

The well stream from Vigdis is routed to Snorre A through two flowlines. Stabilised oil is transported by pipeline from Snorre A to Gullfaks A for storage and export. All produced gas from Vigdis is reinjected into the Snorre reservoir.

Fleet

Rigs drilling, offshore vessels at the facilities in the AIS picture 7 Oct 2026, 14:34 UTC and the supply vessels from the base in the last 30 days.

Visits, latest day with data: 1 Oct

Rigs and offshore vessels that lay within 2 km of a facility at under 1 knot for at least 30 minutes, according to the AIS positions for 1 Oct 2026 from the Norwegian Coastal Administration. Kystdatahuset publishes the history about a week late. A visit shows that the vessel was there, not who it worked for. AIS from Kystverket (Norwegian Coastal Administration, Kystdatahuset historical positions) (NLOD 1.0), latest day 1 Oct 2026 · Norwegian Coastal Administration, Kystdatahuset: register type (SafeSeaNet) (NLOD 1.0), 1 Oct 2026 · Norwegian Offshore Directorate, facilities with position (NLOD 2.0), 7 Oct 2026 · OESA, rig key Sodir ↔ MMSI ↔ IMO (curated) (NLOD 1.0 / NLOD 2.0), 7 Oct 2026

Method: A visit is a continuous stay within 2 km of a facility at under 1 knot for at least 30 minutes, computed from the AIS positions. Gaps in the data of up to 60 minutes, or 3 hours when the vessel is in the same place before and after, do not count as interruptions. Hours are the sum of the visits. Only rigs and vessels with an offshore register type or registered with the Norwegian Offshore Directorate are included.

Supply vessels from the base, last 30 days

Reported departures by offshore vessels (register type in SafeSeaNet). Supply base: Norwegian Offshore Directorate (the field's main supply base); the port's position from the World Port Index, Wikidata or OpenStreetMap (NLOD 2.0 / offentlig eiendom / ODbL), 28 Sep 2026 · Norwegian Coastal Administration, Kystdatahuset: reported voyages and register type (SafeSeaNet) (NLOD 1.0), 6 Oct 2026

Who charters a rig or vessel, and at what rate, is not in open data. A vessel is linked to a field only when AIS shows it within 2 km of one of the field's own facilities or its host facility, at under 1 knot – that says the vessel was there, not who it works for. Facilities on the export route do not count. Tankers loading oil from production ships (FPSOs) and loading buoys are not included. Supply vessels per base are based on reported departures (SafeSeaNet). The destination is usually just the sea area (“Offshoreinst. Nordsjøen”, “… Barentshavet”), so the field the vessel supplies is not stated. Peterhead is British and has no departures in Kystdatahuset. AIS coverage offshore varies. A vessel without positions for a period may have been there without being recorded. Ship data: Norwegian Coastal Administration. Not for navigation.

Check against Statistics Norway

For the whole shelf the method gives NOK 1,180.9 bn for Aug 2025–Jul 2026. Statistics Norway's export value for crude oil, condensate, pipeline gas, LNG, propane and butane was NOK 1,107.3 bn, −6.2% against the estimate. Month by month the difference ranged from −10.5% (June 2026) to −1.0% (January 2026); Statistics Norway was below the estimate in all 12 months. Crude oil and condensate in the trade statistics (commodity numbers 2709.0009 and 2709.0001) were 93% of oil and condensate production, and pipeline gas (2711.2100) was 94% of gas production in the same months. On top of this, 4.35 million tonnes of LNG (2711.1100) were exported. Statistics Norway reports LNG only in tonnes, so it is not included in the gas percentage. The prices in Statistics Norway's export statistics differed on average by −0.8% from Brent and −0.7% from the gas price, but by up to −10.7% for oil in a single month (June 2026). Exports of propane and butane averaged 58% of NGL production converted to tonnes, so the NGL price only covers part of the products.

How the estimate is calculated

Estimated gross sales value, calculated by OESA: for each field and month, (oil + condensate) × 6.2898 bbl/Sm³ × Brent (USD/bbl) × USD/NOK, gas × 0.011111 MWh/Sm³ (40 MJ) × European gas price (EUR/MWh) × EUR/NOK and NGL ÷ 1.9 Sm³ o.e. per tonne × NGL price (NOK/tonne) are added up. A company's figure is the field value times the equity share in force on the 15th of each month, summed over the fields and the group's legal entities. These are not the companies' own figures. Prices in July 2026: Brent USD 83.76/bbl, gas in Europe USD 18.06/mmbtu (EUR 53.97/MWh), NGL NOK 5,142/tonne, USD/NOK 9.7064 and EUR/NOK 11.0822. Sources of error: Brent and TTF are benchmark prices. Actual sales prices depend on crude quality, timing of sales, contracts and hub (NBP, THE, PEG, ZTP). The production month is not the sales month: cargoes are lifted and sold at other times (over/underlift, storage). The energy content of gas is set to 40 MJ/Sm³ for all fields, and NGL to 1.9 Sm³ o.e. per tonne. Both vary between fields. NGL is priced with Statistics Norway's export price for propane and butane; ethane and other NGL products may have other prices. Transport tariffs (Gassled), tax (78%), costs and hedging are not deducted. The figure is market sales value, not netback at the field or profit. LNG from Melkøya is priced as pipeline gas.

All figures and links on the page come from these sources. Curated links are entered by hand by OESA from the source text, and the quote is checked against the source at every build.

Not in the data: Flow in each pipeline, which field's gas ends up in which country, and the buyers of oil and gas. Gas is mixed in the network, so a “possible route” is a pipeline connection, not measured flow.
