10/01/2012 Centrica Resources Norge AS, operator of production licence 405, has concluded the drilling of appraisal well 8/10-4 B about 13 km east of the Ula field in the southern part of the North Sea.
The objective of the well was to prove petroleum in Upper Jurassic reservoir rocks (the Ula formation) in a new segment south of the 8/10-4 S (Butch) oil discovery, proven in 2011. Due to technical problems, the well was terminated before reaching reservoir level. Well 8/10-4 B is the third exploration well in production licence 405. The licence was awarded in APA 2006.
Well 8/10-4 B was drilled to a vertical depth of 2098 metres below the sea surface and terminated in the Hordaland group. The water depth is 66 m. The well has now been plugged and abandoned.
Well 8/10-4 B was drilled by the Mærsk Guardian drilling facility, which will now proceed to production licence 450 to drill wildcat well 7/12-13 S for Det norske oljeselskap.
