ORLEN’s Norwegian subsidiary has completed the purchase of equity in the Albuskjell and Vest Ekofisk fields in the North Sea, adding approximately 8 million barrels of oil equivalent to its resource base.
Both fields, together with Tommeliten Gamma, form part of the Previously Produced Fields (PPF) Project, which has recently been sanctioned for development.
Once brought on stream, the three fields will increase ORLEN Upstream Norway’s production by approximately 420 million cubic metres of gas annually.
Under the agreement signed in November 2025, ORLEN Upstream Norway purchased a 7.6% interest in both Albuskjell and Vest Ekofisk from DNO. Following the fulfilment of all contractual conditions, the transaction was finalised in December 2025.
“We are closing the year with excellent news from the Norwegian Continental Shelf. By acquiring shares in two fields, we are strengthening our position in the Greater Ekofisk Area – the birthplace of Norway’s oil industry.
“ORLEN’s own gas production from the Shelf, combined with production in Poland and LNG imports, forms the backbone of energy security for Poland and the wider region,” said Ireneusz Fąfara, President of the Management Board of ORLEN.
The purchase of shares in Albuskjell and Vest Ekofisk is yet another acquisition completed by ORLEN Upstream Norway in the Greater Ekofisk Area this year.
In October, the company acquired a 20.23% stake in Tommeliten Gamma from TotalEnergies EP Norge, increasing its ownership in the field to 62.61%. All three fields will be developed jointly as part of the PPF Project.
In December, the licence partners reached the final investment decision to develop the PPF.
“ORLEN’s combined reserves from Albuskjell, Vest Ekofisk and Tommeliten Gamma total around 25 million barrels of oil equivalent, including more than 3 billion cubic metres of gas. Holding interests in all three fields gives us financial and operational synergies.
“This allows us to deliver on the objectives of the ORLEN 2035 Strategy in a cost-effective manner, maximising the positive impact of the Upstream business on the Group’s performance,” said Wiesław Prugar, Vice-President of the Management Board of ORLEN for Upstream.
The three fields – Albuskjell, Vest Ekofisk and Tommeliten Gamma – are operated by ConocoPhillips Skandinavia AS, with other partners including Vår Energi ASA and Petoro AS (the latter in Albuskjell and Vest Ekofisk).
The development plan involves drilling 11 production wells, which will be connected to the Ekofisk infrastructure.
First gas is scheduled for Q4 2028. At peak output, ORLEN expects to produce 3.4 million barrels of oil equivalent annually from the PPF, including more than 400 million cubic metres of gas.
