In a notable development for the Norwegian Continental Shelf, energy giants Equinor and Aker BP have announced substantial gas and condensate discoveries in the North Sea, signalling renewed potential for the region’s mature energy landscape. The findings, located in Production Licence 1140, are expected to be commercially viable through tie-backs to existing infrastructure, aligning with a strategic focus on efficient resource recovery in the basin.
The discoveries were made through two wildcat exploration wells situated approximately 7 kilometres north of the Eirin field and about 40 kilometres northwest of the Sleipner A platform, some 240 kilometres west of Stavanger.
Preliminary estimates indicate that one holds recoverable volumes ranging from 22 to 63 million barrels of oil equivalent (mboe), while the other is estimated to contain 6 to 50 mboe. Combined, the gross recoverable volumes are estimated at 30 to 110 mboe. Drilling operations were conducted by Odfjell Drilling’s Deepsea Atlantic rig, a sixth-generation semi-submersible designed for harsh environments.
Equinor, the operator with a 60% working interest, and partner Aker BP, holding 40%, will now evaluate development options, focusing on economically efficient tie-backs to existing North Sea infrastructure. This approach, which can reduce development costs by 60 to 80 percent compared to standalone facilities, is increasingly crucial for maximising value from smaller discoveries in mature areas.
Kjetil Hove, Equinor’s Executive Vice President for Exploration & Production Norway, underscored the broader strategic importance of these finds: “This demonstrates the importance of maintaining exploration activity on the Norwegian Continental Shelf. There are still significant energy resources on the shelf, and Europe needs stable oil and gas deliveries. Discoveries near existing fields can be developed quickly through subsea facilities, with limited environmental impact, very low CO2 emissions from production, and strong profitability. Equinor plans to accelerate such developments on the Norwegian Continental Shelf.”
For Aker BP, the discoveries cap a particularly successful year for exploration. Karl Johnny Hersvik, CEO of Aker BP, stated: “The Lofn and Langemann discovery marks the conclusion of a strong exploration year for Aker BP. Across three major discoveries, we have added more than 100 million barrels net to the company, including Omega Alfa and Kjøttkake earlier this year.”
He further added: “This makes 2025 our most successful exploration year since Johan Sverdrup was discovered in 2010. These results are key to sustaining production above 500,000 barrels per day into the 2030s. The progress achieved this year reinforces our confidence in delivering on that trajectory.”
The Eirin field, to which the new discoveries are located nearby, is itself under development with production slated for 2025, to be tied back to the Gina Krog platform.
Production Licence 1140 was awarded in 2022 through Norway’s Awards in Predefined Areas (APA) licensing round. These annual rounds are designed to encourage exploration in mature areas with established infrastructure, thereby ensuring the continued efficient use of the Norwegian Continental Shelf.
The partnership between Equinor and Aker BP exemplifies a growing trend of collaboration in mature basins, leveraging complementary strengths to distribute risk and optimise portfolios. As Europe continues to seek stable and reliable energy supplies, particularly natural gas, Norway’s continued exploration success and focus on infrastructure-led development remain vital for regional energy security.
