Lundin Energy Norway AS will plug Barents Sea well 7221/4-1. The well, drilled in production license 609 as a shared well between Lundin-operated production licenses 609 and 1027, is dry.

The well—the 11th in the license—was drilled to a vertical depth of 1,537 m subsea by the West Bollsta drilling rig about 30 km east of Johan Castberg field, about 12 km east of the 7220/6-2 R (Neiden) oil and gas discovery, and 230 km northwest of Hammerfest. It was terminated in carbonate-bearing rocks from the Late Permian age (Røye formation). Water depth at the site is 370 m.

The primary and secondary exploration targets for the well were to prove petroleum in reservoir rocks in the Kobbe formation from the Middle Triassic age and the Havert formation from the Early Triassic age.

In the primary target, the well encountered a 6-m sandstone layer with poor reservoir quality. There were traces of petroleum. No reservoir rocks were encountered in the secondary target. Extensive data acquisition was carried out.

The drilling rig will now drill well 7219/11-1 in production license 533 B, where Lundin Energy Norway AS is operator.
