Eni Norge AS, operator of production license 697, has completed the drilling of wildcat well 7122/10-1 S. The well, which was drilled about 10km southwest of Goliat field, is dry.
The primary exploration target for the well was proving petroleum 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).
Well 7122/10-1 S 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 snadstone 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 is classified as dry. Samples have been taken and extensive volumes of data have been acquired.
This is the first exploration well in production license 697. The license was awarded in APA2012.
Well 7122/10-1 S was drilled to vertical depth and measured depths of 1,298m and 1,491m below the sea surface, respectively, and the well was terminated in the Kobbe formation in the Middle Triassic.
Water depth is 342m. The well will be permanently plugged and abandoned.
Well 7122/10-1 S was drilled by Scarabeo 8, which has now completed the contract with Eni Norge AS.
