Eni bites dust in Goliat Eye wildcat well

Eni Norge has hit dust in the Goliat Eye wildcat well (7122/10-1 S) in the Barents Sea, offshore Norway.

The Norwegian Petroleum Directorate said on Wednesday that the primary exploration target for the well was proving petroleum in Middle Triassic reservoir rocks (Kobbe formation).

To remind, the Petroleum Safety Authority (PSA) gave Eni Norge a consent to drill the well using the Scarabeo 8 drilling rig in late August. The rig has now completed its contract with Eni.

The consent allowed Eni to drill well 7122/10-1 S in production license 697 to investigate an exploration prospect named Goliat Eye. The well was drilled about 10 kilometers southwest of the Goliat field.

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

Well 7122/10-1 S was drilled to vertical depth and measured depths of 1,298 meters and 1,491 meters below the sea surface, respectively, and the well was terminated in the Kobbe formation in the Middle Triassic.

This is the first exploration well in production license 697, awarded in APA2012. Eni classified the well as dry and took samples and acquired extensive volumes of data. Water depth at the site is 342 meters, and the well will be permanently plugged and abandoned.
