UK-based oil and gas company Harbour Energy and its partners have identified a gas and condensate discovery at the Camilla Nord prospect in the Gjoa area, offshore Norway.
The find was made at wildcat wells 35/8-8 S and 35/8-8 A, drilled using the Transocean Norge rig, in production licences 248 LS and 248 B, part of the Vega Unit in the North Sea.

Licence 248 B was granted in 2006 as part of the Awards in Predefined Areas (APA) 2005 round, while 248 LS was awarded in 2025 as additional acreage for licence 248 B under APA 2024.
The discovery is set to be linked back to the existing infrastructure at the Vega field.
According to preliminary estimates, the discovery size is between 400,000 and 800,000 standard cubic metres of recoverable oil equivalent, which equates to around 2.2–4.7 million barrels of oil equivalent.
The well 35/8-8 S encountered a 26m gas column in the Tarbert Formation, with 10m of sandstone of poor reservoir quality, and no gas-water contact was found.

By GlobalDataIn the Etive Formation, it identified two gas columns, measuring 2m and 4m, in a total of 6m of sandstone with moderate reservoir properties.
The gas-water contact for the upper column was at 3,752m below sea level, while the lower column did not encounter a contact.
At the other main exploration target, the well intersected reservoir rocks from the Early Jurassic (Cook Formation), with 123m thickness in 34m of sandstone having moderate reservoir properties.
The well also intersected 238m of Late Jurassic (Heather Formation) rocks, with 39m of sandstone with poor reservoir properties.
Additionally, the well had a 2m gas column in reservoir rocks from the Early Jurassic (Drake Formation) totalling 1m sandstone, with reservoir properties being poor to moderate.
The well 35/8-8 S reached a final depth of 4,146m below sea level in the Amundsen Formation.
The well 35/8-8 A, aimed at confirming hydrocarbons in the Middle Jurassic Brent Group, encountered 139m-thick reservoir rocks from the Brent Group reservoir, with 53m of sandstone ranging from good to poor reservoir properties.
It encountered a 2m gas column in the Ness Formation, with gas-water contact at 3,654m below sea level.
The well also encountered 214m of Heather Formation, with 36m of poor-quality sandstone, and was drilled to 3,789m below sea level in the Rannoch Formation.
Neither well underwent formation testing, but the operators conducted comprehensive data acquisition and sampling. The water depth at the site is 375m.
Both wells have been permanently plugged and abandoned.
This month, Harbour Energy signed an agreement to acquire substantially all subsidiaries of Waldorf Energy Partners and Waldorf Production for $170m (£127.1m).
