30/11-10

22/12/2014 Statoil Petroleum AS, operator of production licence 035, is about to complete drilling of wildcat well 30/11-10. The well proved oil.

The well was drilled just north of the 30/11-8 S gas/oil/condensate discovery which was made in 2011, and about 25 kilometres southwest of the Oseberg South field in the northern part of the North Sea.

The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks (Tarbert, Ness and Etive formations). Well 30/11-10 encountered an oil column of a total of 80 metres in the upper to middle Tarbert formation and 20 metres in the Etive formation, both with generally poor reservoir properties. Mobile oil was encountered in the Ness formation in good quality reservoir rocks.

Preliminary calculation of the size of the discovery is between one and three million Sm3 recoverable oil equivalents. The licensees will evaluate the discovery together with the development of other discoveries in the production licence.

The well was not formation tested, but extensive data acquisition and sampling were carried out.

This is the eighth exploration well in production licence 035. The licence was awarded in the 2nd licensing round in 1969.

Well 30/11-10 was drilled to a vertical depth of 4054 metres below the sea surface, and was terminated in the Dunlin group in the Lower Jurassic. Water depth is 105 metres.

Well 30/11-10 was drilled with the Transocean Leader drilling facility, which will drill sidetrack well 30/11-10 A after completing this well.
