The well was drilled just north of the 30/11-8 S gas/oil/condensate discovery which was made in 2011, and about 25 kilometers 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 meters in the upper to middle Tarbert formation and 20 meters 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 license. The well was not formation tested, but extensive data acquisition and sampling were carried out.
