Oil & Gas Company Equinor Discovers New Gas Reserves In Norwegian Sea

Equinor in partnership with Okea and Pandion Energy has made a gas and condensate discovery in the Mistral Sør exploration well, located in the Halten area of the southern Norwegian Sea.

Per reports, the discovery contains about 3 to 7 million standard cubic meters of recoverable oil equivalent (o.e.) which is approximately 19 to 44 million barrels.

The discovery is in a well-developed area with existing gas infrastructure, increasing its commercial capacity.

The company highlighted the importance of Norwegian gas for Europe’s energy security and stated that continued exploration is necessary to maintain stable supply levels.

It also announced that multiple discoveries have been made in this area in recent years, which has further strengthened its position as a major production hub.

The Mistral Sør discovery lies in the Asgard and Kristin area of the Norwegian Sea, close to Linnorm, which is the largest undeveloped gas discovery on the Norwegian continental shelf (NCS).

Equinor assumed operatorship of Linnorm in 2023. The region has seen regular exploration activity, with another discovery made in 2024 at the Lavrans field.

Lavrans is currently being developed and will be tied back to the Kristin Sør field.

The Mistral Sør well, 6406/6-7 S, was drilled by the Deepsea Atlantic rig under production licence 1119. The main target of the well was to confirm petroleum deposits in the Middle Jurassic Garn Formation, with a secondary target in the Ile Formation.

The well encountered a 45-meter hydrocarbon column in the Garn Formation, with good reservoir properties. However, no hydrocarbons were found in the secondary target.

The well was drilled to a vertical depth of 4,024 meters below sea level and was terminated in the Lower Jurassic Ror Formation. The water depth at the site is 256 meters.

Extensive data collection and sampling were conducted. Despite the well being permanently plugged, the commercial viability of the discovery means the licensees will now assess whether to tie it back to existing infrastructure or develop it alongside other nearby discoveries.

After this operation, the Deepsea Atlantic rig will move to its next drilling project at 15/8-G-4 Utgard.
