Equinor Discovers Gas and Condensate in Mistral Sør Well in Norwegian Sea

Equinor and its partners have made a significant discovery of gas and condensate in the Mistral Sør exploration well in the Halten area of the Norwegian Sea. This discovery further bolsters Norway’s position as a key gas supplier to Europe.

The estimated recoverable oil equivalent in the Mistral Sør well ranges between 19-44 million barrels, showcasing the potential of the find. Grete B. Haaland, Equinor’s senior vice president for Exploration & Production North, emphasized the importance of Norwegian gas in meeting Europe’s energy demands.

The Mistral Sør well is situated in the Åsgard and Kristin area, north of the Linnorm field, which is the largest undeveloped gas discovery on the Norwegian continental shelf. This discovery adds to the region’s recent successes, including the Lavrans field find in 2024, which is set to be tied back to the Kristin Sør field.

Technical details of Well 6406/6-7 S reveal a 45-meter hydrocarbon column in the Garn Formation with promising reservoir properties. The well reached a depth of 4,024 meters below sea level in water depths of 256 meters.

Licensees have confirmed the commercial viability of the discovery and are exploring tie-back options to existing infrastructure or joint development with nearby discoveries. Equinor Energy ASA operates the license with a 50% stake, while Okea and Pandion Energy hold 30% and 20% interests respectively, with the license awarded during APA 2020.

Upon completion of operations, the Deepsea Atlantic drilling rig will move to the 15/8-G-4 Utgard location to commence drilling activities.
