30/11-8 S

10/05/2011 Statoil Petroleum AS, operator of production licence 035, is in the process of completing the drilling of wildcat well 30/11-8 S. The well is located about 26 kilometres southwest of the Oseberg Sør field in the North Sea.

The well was drilled in production licence 035, along with production licence 272, which has the same owners and ownership interests.

The primary exploration target for the well was to prove petroleum in reservoir rocks from the Middle Jurassic Age (the Brent group).

The secondary exploration target was to prove petroleum in the Sele formation from the Palaeocene Age. Hydrocarbons were proven in a 200-metre column in the Brent group, in reservoir rocks with good reservoir quality. Preliminary data indicates oil.

The secondary exploration target in the Palaeocene is dry. Preliminary estimates indicate the size of the discovery at between two and nine million Sm3 recoverable oil equivalents. The well was not formation tested, but extensive data acquisition and sampling have been carried out.

The well is the sixth exploration well in production licence 035, which was awarded in the second licensing round in 1969.

30/11-8 S was drilled to a vertical depth of 3822 metres below the sea surface, and was terminated in the Dunlin group, in Early Jurassic rocks. The water depth is 108 metres.

The well will now be permanently plugged and abandoned.

Well 30/11-8 S was drilled by the Ocean Vanguard drilling rig which, upon completing this well is to drill a sidetrack, wildcat well 30/11-8 A on a prospect to the west of 30/11-8 S, in production licence 035/272, where Statoil Petroleum AS is the operator.
