Fossil Energy – Oil Discovery
Equinor and its partners have proven oil in wildcat well 6507/8-12 S in production licence 124 B.

The well tested the Othello South prospect, 4 kilometres north of the Heidrun field and 240 kilometres west of Sandnessjøen.
Preliminary estimates indicate the size of the discovery is between 0.15 and 2 million standard cubic metres (Sm3) of recoverable oil equivalent. This corresponds to 0.95 – 12.6 million barrels of recoverable oil equivalent.
Production licence 124 B was carved out from production licence 124 on 30 September 2024. Nine exploration wells have already been drilled in production licence 124, and this is the first exploration well in production licence 124 B.
The licensees will assess the discovery with a view toward further developing the northern part of the Heidrun field.
The well was drilled by the Cosl Innovator drilling rig, which is now moving on to drill well 6610/7-U-3 in production licence 1014 in the Norwegian Sea. The objective of the well is to verify potential shallow gas deposits.
