Equinor and its partners on the Troll gas development project have agreed to invest over NOK12 billion (US$1.1 billion) to further develop the infrastructure in the Troll West gas field in the Norwegian sector of the North Sea.
Equinor said this will accelerate production from the reservoir and thus maintain the current high gas export levels from the Troll and Kollsnes value chain leading up to 2030.
Stage two of the Troll Phase three project includes eight new wells from two new templates with subsea controls extended from existing templates. 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.
The new infrastructure will accelerate production from the reservoir equivalent to about 55 billion standard cubic metres of gas. At its peak, the annual contribution from the new development will amount to around seven billion standard cubic metres of gas.
