A well drilled 10km southwest of the producing Goliat oilfield in the Norwegian Barents Sea by Italian major Eni was dry, says the Norwegian Petroleum Directorate.

Well 7122/10-1 S was targeting hydrocarbons in Middle Triassic reservoir rocks (Kobbe formation). Secondary exploration targets were to prove petroleum in Upper Triassic to Lower Jurassic reservoir rocks (Realgrunn sub-group and Snadd formation) and, depending on the well result, in Lower Triassic reservoir rocks (Klappmyss formation).

The encountered about 35m of reservoir rocks in the Kobbe formation with moderate to good reservoir quality. In the secondary exploration target, the well encountered about 35m of sandstone reservoir in the Realgrunn sub-group with good reservoir quality, and about 80m of sandstone reservoir in the Snadd formation with moderate to good reservoir quality.

There were traces of oil in the Realgrunn sub-group, and a core was taken. The Snadd and Kobbe formations are aquiferous. The well was classified as dry, says the NPD. 

It was the first exploration well in production license 697, which was awarded in APA2012. 

Well 7122/10-1 S was drilled to vertical depth and measured depths of 1298m and 1491m below the sea surface, respectively, and the well was terminated in the Kobbe formation in the Middle Triassic.

The well was drilled using the Scarabeo 8 in 342m water depth.
