Equinor signed contracts worth $610 million to develop four offshore fields in Norway

Moscow, July 8 – Neftegaz.RU. Equinor has awarded contracts worth around NOK 6 billion for four subsea projects. They are part of the first of several planned subsea development waves, in which contracts are being coordinated to increase pace and reduce costs for subsea developments on the Norwegian continental shelf.

According to the Equinor, these are the contracts:

• TechnipFMC will deliver subsea production systems for Brime, Omega Sør and Tyrihans Nord. They will also install rigid pipelines on the Troll field. The linepipe will be supplied by Tenaris;
• OneSubsea will deliver the subsea production system for the TWIN project, as well as umbilicals for all the projects;
• Ocean Installer has been awarded the contract for marine operations. They will install and connect the subsea facilities, control cables and flexible pipelines;
• NOV will deliver flexible pipelines to Omega Sør, Tyrihans Nord and Brime.

The relevant subsea projects are:

• TWIN, which will be tied back to Troll A;
• Omega Sør, which is planned to be tied back to Snorre A;
• Tyrihans Nord, which is planned to be produced via the Kristin platform;
• Brime, which is planned to be tied back to Gullfaks C via Visund Sør existing template on the seabed.

Together, the four projects will contribute between 130 and 220 million barrels of oil equivalent to future production from the Norwegian continental shelf.

So far, only the TWIN project has been sanctioned by the owners and in accordance with the Petroleum Act the partnership has sent notification to the Ministry of Energy regarding the development. The remaining projects will be processed and sanctioned in accordance with the decision-making processes of the partnerships and the authorities.

Projects in wave 1:

TWIN (Troll West Increased Gas Recovery North)

• the third step in a phased development of the gas cap in Troll West;
• the partnership has decided to invest just over NOK 4 billion in the project, which will contribute around 11 billion standard cubic metres of gas$
• the project consists of two wells in a new template and a pipeline connected to existing subsea facilities;
• the control cable and MEG line will be extended to the new development;
• the gas will be produced via Troll A before being sent to Kollsnes.

TWIN stands for Troll West Increased gas recovery North – increased recovery of gas in the northern part of the gas cap in Troll West.

Partnership: Equinor Energy AS 30.55% (operator), Petoro AS 55.93%, A/S Norske Shell 8.19%, TotalEnergies EP Norge AS 3.69% and ConocoPhillips Skandinavia 1.64%.

The other projects are currently in the early phase.

Brime

• planned to be developed with four wells drilled from a template tied back to an existing subsea template at Visund Sør;
• the wellstream, which is mainly gas, will be sent to Gullfaks C for processing before being transported onwards to Kårstø for export.

Brime also provides the basis for a possible phased development of Nøkken, planned as sidetracks from two of the wells at Brime. Recoverable volumes in Brime are estimated at 16–34 million barrels of oil equivalent. Partnership: Equinor Energy AS 74.66% (operator), Petoro AS 25.34%.

Omega Sør

• an oil discovery made near the Snorre field in spring 2026, with recoverable volumes then estimated at between 25 and 89 million barrels;
• the discovery is planned to be developed with a template and a Cap-X production satellite connected to existing subsea facilities;
• the oil is planned to be produced via Snorre A before being shipped to market via Gullfaks.

Partnership: Equinor Energy AS 31% (operator), Petoro AS 30%, Harbour Energy Norge AS 24.5%, INPEX Idemitsu Norge AS 9.6%, Vår Energi ASA 4.9%.

Tyrihans Nord

• a discovery from 1984 that is planned to be developed with two wells in a new template connected to the existing production pipeline between the Tyrihans subsea field and the Kristin platform in the Norwegian Sea;
• the gas will be sent onwards to Kårstø.Volumes are estimated at between 20 and 30 million barrels of oil equivalent, mainly gas.

Partnership: Equinor Energy AS 36.32% (operator), TotalEnergies EP Norge AS 23.15%, Petoro AS 22.52%, Vår Energi ASA 18.02%.

Additional Projects

The first phase of development also includes the Sissel field, discovered in January 2026. The development plan has been simplified: instead of building new infrastructure, the existing Utgard system will be used. Reserves are estimated at 6–28 million boe. Partners: Equinor Energy AS 50% (operator), Orlen Upstream Norway AS 50%.

As a reminder, the company expects to maintain production on the Norwegian continental shelf at 1.3 million boe per day, with about 70% of this volume to be provided by new wells. Earlier, Equinor signed a memorandum of understanding with the Swiss company Transocean worth approximately $1 billion, providing for the use of three Category D semi-submersible drilling rigs to drill wells on the Norwegian continental shelf.

This agreement is also part of the company’s long-term program to increase production on the Norwegian continental shelf. By 2035, Equinor plans to:

• drill more than 125 wells annually,
• carry out approximately 75 subsea projects,
• conduct about 200 well abandonment and plugging operations.
