Norway: More gas for 30-year-old Troll A
Equinor and partners (Shell, TotalEnergies, ConocoPhillips, Petoro) started gas production from Troll Phase 3 stage 2 in the North Sea, accelerating output by 55 billion cubic meters. The project, completed under budget and ahead of schedule, supports European gas supplies and Norwegian jobs. Troll accounts for 10% of Europe's gas demand and 40% of Norway's reserves.
