TWIN

Equinor and its Troll licence partners took final investment decision on TWIN (Troll West Increased Gas Recovery North) on 19 June 2026, committing NOK 4 billion to unlock an estimated 11 billion cubic metres of additional recoverable gas. First production is targeted for 2028. The project landed one week after the EU's short-term ban on remaining Russian pipeline gas volumes came into force, reinforcing Norwegian supply as the structural answer to European import diversification.

TWIN is a brownfield subsea tieback to existing Troll A infrastructure on the Norwegian Continental Shelf, operated by Equinor with partners Petoro (55.93%), Shell (8.19%), TotalEnergies (3.69%), and ConocoPhillips (1.64%). The Troll field has been in production since 1996 and already supplies roughly 11% of Europe's gas imports; TWIN extends its productive life and partially offsets natural decline in the western part of the reservoir.

For European gas markets, TWIN is a 2028-horizon commitment with no effect on the current injection season or winter 2026/27 storage builds. Its significance is structural: it anchors Norwegian shelf investment at a point when European buyers are locking in long-term supply contracts outside Russian dependency, and it demonstrates continued commercial confidence in Norwegian Continental Shelf development despite an uncertain forward price curve.
