BG Norge AS, operator of production licence 373 S, is completing drilling of exploration well 34/3-5, located approximately five km southeast of the Knarr Field in the Northern North Sea, around 120 km West of Florø. The well is dry.
The objective of well 34/3-5 was to prove petroleum in Early Jurassic reservoir rocks (Cook Formation). Well 34/3-5 encountered a gross Cook Formation interval of approximately 82m, of which 47m were good reservoir quality with traces of residual hydrocarbons interpreted.
According to the Norwegian Petroleum Directorate (NPD), extensive data acquisition and sampling has been carried out. The well is classified as dry.
The well was the seventh exploration and appraisal well in production licence 373 S, which was awarded in APA 2005.
The well was drilled to a total vertical depth of 4,253m below the sea surface (4,275m measured depth), and terminated in the Lower Jurassic Amundsen Formation. The water depth is 403 m. The well will now be permanently plugged and abandoned.
The 34/3-5 well was drilled by the Transocean Searcher semi-submersible drilling rig. The rig will be left in Kristiansund for approximately 2 months prior to starting opeations in the North Sea where it will move on to drill well 2/11-11 in production license 616 where Edison Norge AS is the operator.
