New oil & gas discovery set to join North Sea fast-track plays fuelling Europe’s energy security

Equinor, Petoro, and TotalEnergies have found up to 50 million barrels in the North Sea and are eyeing first production in under three years.

After striking between 19 and 50 million barrels of recoverable oil equivalent (boe), corresponding to 3-8 million standard cubic meters, at the exploration well 30/8-7 S, known as the Grimsnes prospect, near the Oseberg field , Equinor and its partners, Petoro and TotalEnergies, are planning a fast and cost-effective development.

The well was drilled in production license PL 190 by the Deepsea Bergen semi-submersible rig around 15 kilometers southwest of the Oseberg Sør platform and 145 kilometers west of Bergen.

According to the Norwegian Offshore Directorate, 30/8-7 S is the fifth exploration well to be drilled in production license 190 , which was awarded in the 14th licensing round on the NCS in 1993.

The well was drilled to a vertical depth of 3,752 meters below sea level and terminated in the Drake Formation in the Lower Jurassic, with extensive data collected and samples taken.

The water depth at the site is 96 meters.

The well has been permanently plugged and abandoned.

While the primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks in the Tarbert Formation, the secondary exploration target was to prove petroleum in Middle Jurassic rocks in the Ness and Etive formations.
