Eirin

The Eirin gas field entered production on 5 May 2026, a few days after EU aggregate storage sank to its lowest seasonal level since 2018. The field, located approximately 250 km west of Stavanger in roughly 120 m of water, holds an estimated 27.6 million barrels of oil equivalent (mmboe) of recoverable resources, predominantly gas. Gas exports route via a tie-back to the Gina Krog platform, then through Sleipner A into the Gassled pipeline network for delivery to Continental European and UK markets.

The licence is split 58.7% Equinor / 41.3% ORLEN Upstream Norway, the upstream Arm of Polish state-controlled PKN ORLEN. Equinor serves as operator. The Eirin development is a classic NCS tail-end tie-back: no standalone platform, no new export pipe, maximum re-use of existing infrastructure. Gina Krog's operational life has been extended by seven years to 2036 as a direct result.

For European buyers, Eirin's timing matters as much as its volume. Norwegian gas already supplies roughly 25–30% of EU gas consumption; the Sodir March 2026 production print recorded a second consecutive month of marginal year-on-year decline, making any incremental NCS field meaningful at the margin. Eirin's output enters Gassled at a moment when the EU refill bill has been priced at EUR 26 bn and every additional bcm from existing infrastructure reduces the call on costlier spot LNG.
