Equinor plans to invest more NOK 12 billion (approximately US$1.1 billion) to develop gas infrastructure in the Troll West gas province, in the Norwegian North Sea, it said in a May 24 release.
The plan is to accelerate production from the reservoir and maintain high gas export levels from the Troll and Kollsness (operated by Gassco) value chain leading up to 2030.
Stage 2 of the Troll Phase 3 project includes eight new wells from two new templates with subsea controls extended from existing templates, Equinor said A new gas flowline will be laid as a tie-back to the Troll A platform, and the project will also perform modification work on Troll A. The first wells are scheduled to come on stream at the end of 2026.
“This is a highly profitable project that will secure high gas production from the Troll field. The partnership’s decision is important in order for us to fully utilize the capacity of existing infrastructure. We’ve chosen to use solid, familiar suppliers, most of which already have framework agreements with us,” says Geir Tungesvik, Equinor’s executive vice president, Projects, Drilling & Procurement (PDP).
Equinor said the new infrastructure will accelerate production from the reservoir equivalent to about 55 billion standard cubic meters of gas. At its peak, the annual contribution from the new development will amount to around 7 billion standard cubic meters of gas.

The first stage of gas production from the Troll West gas province started in 2021 and included eight wells and a new pipeline to the Troll A platform, as well as a new inlet module. This part of the project helped extend plateau production by 5-7 years. Stage 2 will further extend plateau production by around four years and reduce the production decline over the next 10-12 years.
Troll is Norway’s largest gas producer, with substantial reserves still underground.
The Troll project is operated by Equinor Energy AS (30.58%). Its partners are Petoro AS (56%), AS Norske Shell (8.10%), TotalEnergies EP Norge AS (3.69%), ConocoPhillips Skandinavia AS (1.62%).
