Vår Energi ASA confirmed the Zagato oil discovery in production license (PL) 229 in the Goliat area of the Barents Sea, the Norwegian Offshore Directorate said in a Jan. 16 release.
The licensees are considering a tieback of the discovery, which is preliminarily estimated to hold 3.3-11.9 million std cu m of recoverable oil (21-75 MMboe), to existing Goliat field infrastructure.
Drilling details
Appraisal well 7122/8-3 A, the 14th well drilled in the license, was drilled in 410 m of water by the COSLProspector rig to 2,285 m MD and 2,268 m TVD subsea. Drilling was terminated in the Kobbe formation in the Middle Triassic. The well's objective was to delineate the 7122/8-3 S Zagato discovery in the formation.
The discovery was proven in Lower Jurassic-Upper Triassic reservoir rocks in the Realgrunnen Subgroup and in Middle Triassic reservoir rocks in the Kobbe formation in 2025.
The well encountered multiple oil columns totaling 63 m in the Kobbe formation in reservoir rocks comprising a total of 38 m with moderate to good reservoir quality. The total thickness in the Kobbe formation is 189 m. Oil-water contacts were encountered 2,098 m and 2,187 m subsea in respective upper and lower reservoir zones in the Kobbe formation. The oil-water contact was not encountered in the middle reservoir zone in the Kobbe formation. The well has been permanently plugged.
Vår Energi is operator of PL 229 (65%) with partner Equinor Energy AS (35%).
