The TWIN project is expected to deliver 11 billion cubic metres of gas, with start-up planned for 2028 as part of the Troll phase 3 expansion.
Moscow, June 19 – Neftegaz.RU. Equinor and its partners Petoro, Shell, TotalEnergies og ConocoPhillips are investing just over NOK 4 billion in a new subsea development that will increase gas production from the Troll field in the North Sea.
«We have an ambition to start production as early as 2028. By simplifying, increasing standardisation and reusing existing infrastructure and equipment, we are reducing costs and enabling faster production, in line with our new ways of working. The project helps sustain jobs, value creation and secure gas exports to Europe from Troll A and Kollsnes», says Gunnar Nakken, senior vice president for projects and subsea Norway in Equinor.
The TWIN project is expected to contribute around 11 billion standard cubic metres of gas. It is the third step of Troll phase 3, which produces gas from the Troll West reservoir. TWIN is short for Troll West Increased gas recovery North.
The second step will come on stream during 2026 and will ensure continued high production from Troll A and Kollsnes towards 2030. Both the platform and the onshore plant are powered by electricity from shore, meaning the gas will be produced with very low emissions.
The project consists of two wells in a template and a pipeline connected to existing subsea facilities. The umbilical and MEG line will be extended to the new development.
«Our ambition is to halve costs and execution time for our subsea projects and develop six to eight such projects per year towards 2035», says Nakken.
Equinor aims to produce 1.3 million barrels per day from the Norwegian continental shelf in 2035.
Facts about TWIN project
Partnership:
- Equinor Energy AS 30,55 % (operator),
- Petoro AS 55,93 %,
- A/S Norske Shell 8,19 %,
- TotalEnergies EP Norge AS 3,69 %,
- ConocoPhillips Skandinavia AS 1,64 %.
In accordance with the Petroleum Act, the partnership will now send an announcement to the Ministry of Energy concerning the development. An environmental impact assessment has been carried out.
About the Troll field
- contains about 40 per cent of the total gas reserves on the Norwegian continental shelf and constitutes the cornerstone of Norwegian gas production;
- the gas from Troll alone meets around 10% of Europe's gas needs;
- annual energy production from the Troll field is equivalent to about three times annual Norwegian hydropower production.
The new investment
follows the recent concept approval for Ringvei Vest – a larger subsea development linked to the Troll B platform. That initiative combines seven discoveries and one prospect into a single project, paving the way for a potential unified field development.
