Mobile oil was encountered in the Ness formation in good quality reservoir rocks.Preliminary calculation of the size of the discovery is between 1 - 3 million m3 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 4054m below the sea surface, and was terminated in the Dunlin group in the Lower Jurassic. Water depth is 105m.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.
