11/06/2009 Press Release 33/2009: StatoilHydro Petroleum AS has concluded the drilling of wildcat well 6407/8-5 S and appraisal well 6407/8-5 A. The wells are located 20 km northeast of the Njord field and 10 km west of the Draugen field in the Norwegian Sea, and both yielded positive results.
The purpose of the wildcat well was to prove petroleum in Jurassic reservoir rocks. Wildcat well 6407/8-5 S proved oil in Lower Jurassic reservoir rocks.
Well 6407/8-5 A was drilled as a sidetrack to delineate the discovery. The well confirmed the oil column in Lower Jurassic reservoir rocks. In addition, the sidetrack proved oil in Middle Jurassic reservoir rocks.
The size of the discovery is between three and five million standard cubic metres of recoverable oil. Neither of the wells were formation-tested, but extensive data collection and sampling were carried out. The licensees will evaluate the size of the discovery in more detail before considering a development solution.
These are the third and fourth exploration wells in production licence 348.
6407/8-5 S was drilled to a vertical depth of 2347 metres below the sea surface and was concluded in the Åre formation in the Lower Jurassic. Well 6407/8-5 A was drilled to a vertical depth of 2123 metres in the Tilje formation in the Lower Jurassic. The wells will be permanently plugged and abandoned.
The wells were drilled in 247 metres of water using the West Alpha drilling facility, which will now be moved to production licence 407 in the North Sea to drill appraisal well 17/12-4, where BG Norge AS is the operator.
