07/09/2009 StatoilHydro Petroleum AS, operator of production licence 074, has completed the drilling of wildcat well 6407/2-5 S.
The well, which proved gas and oil, is located 12 kilometres south of the Midgard gas discovery 6507/11-1 on the Åsgard field in the Norwegian Sea.
The purpose of the well was to prove gas in Middle Jurassic reservoir rocks (the Garn and Ile formation). The well proved gas in the Garn formation and oil in the Ile formation. Preliminary calculations indicate that the size of the discovery is one to two billion standard cubic metres of recoverable gas and two to five million standard cubic metres of recoverable oil.
The well was not formation-tested, but extensive data acquisition and sampling have been carried out. The licensees in the production licence are considering development concepts to produce the discovery using existing infrastructure on the Åsgard field.
The well is the fourth exploration well in production licence 074, which was awarded on 23 April 1982 in the 5th Licensing Round.
The well was drilled to a vertical depth of 3 289 metres below sea level and terminated in rock of the Lower Jurassic age in the Åre formation. The well will be permanently plugged and abandoned.
Well 6407/2-5S was drilled by the drilling facility Ocean Vanguard at a water depth of 250 metres. The facility will now proceed to production licence 442 in the North Sea to drill wildcat well 25/2-17, which is operated by StatoilHydro Petroleum AS.
