(IN BRIEF) Equinor has made two major gas and condensate discoveries, Lofn and Langemann, in the Sleipner area of the North Sea, with recoverable estimates ranging from 30 to 110 million barrels of oil equivalents. The discoveries can be swiftly developed using existing infrastructure to support energy supply to Europe. Executives underscored the importance of continued Norwegian continental shelf exploration and highlighted the benefits of low-emission subsea tie-back development. Identified using Ocean Bottom Node seismic technology, the wells were drilled by the Deepsea Atlantic rig and form part of a broader push to secure long-term production capacity, supported by upcoming exploration wells. The license is jointly held by Equinor (60%) and Aker BP (40%).

(PRESS RELEASE) STAVANGER, 5-Dec-2025 — /EuropaWire/ — Equinor has announced two significant new gas and condensate discoveries in the Sleipner area of the North Sea — marking the company’s largest finds so far this year. Named Lofn and Langemann, the wells sit within production license 1140 between the Gudrun and Eirin fields. Early assessments suggest combined recoverable volumes of 5–18 million standard cubic metres of oil equivalents, equal to approximately 30–110 million barrels, and importantly, the resources can be tied into existing infrastructure for development aimed at the European energy market.

Kjetil Hove, Equinor’s Executive Vice President for Exploration & Production Norway, emphasised that the discoveries highlight the value of continued exploration on the Norwegian continental shelf. He noted that locating new resources near existing fields enables rapid development through subsea tie-backs, with limited environmental footprint, low production emissions, and strong commercial potential — contributing to Europe’s need for secure energy supply. Equinor aims to accelerate similar fast-track developments across the shelf in coming years.

The license was awarded under the 2022 APA round, where advanced Ocean Bottom Node (OBN) seismic technology — with sensors placed on the seabed — played a key role in identifying the drilling targets. Hove added that the Sleipner region remains a strategic gas export hub, and the new discoveries improve prospects for future exploration. In collaboration with partners, Equinor plans to drill five additional wells in the area to further grow resource volumes and maintain export capacity.

Drilling was carried out using the Deepsea Atlantic rig, which will now proceed to the next well in the exploration programme. License ownership consists of Equinor Energy AS (60%) and Aker BP ASA (40%). The discoveries were made in the Hugin Formation, with high-quality sandstone reservoirs and high-pressure/high-temperature characteristics.
