09/03/2009 Press Release 14/2009: StatoilHydro Petroleum ASA, operator of production licence 104, has concluded the drilling of wildcat well 30/9-22. The well is located about 11 km southwest of the Oseberg Sør platform in the North Sea.
The purpose of the well was to prove petroleum in Middle Jurassic reservoir rocks (the Brent group).
The well proved gas in Upper Jurassic reservoir rocks belonging to the Heather formation, as well as gas and oil in the upper part of the Brent group. The proven recoverable volumes are 8-13 million Sm3 oil equivalents, with most of the resources located in the upper part of the Brent group. The discovery has not been tested, but extensive data collection and sampling have been carried out. The discovery will probably be developed and produced as a tie-in to one of the seabed facilities in the Oseberg area.
The well is the 20th exploration well in production licence 104, which was awarded in the 9th licensing round in 1985.
The well was drilled to a vertical depth of 3231 metres below the sea surface, and was concluded in rocks from the Early Jurassic Age.
The water depth at the site was 95 metres. The well will now be permanently plugged and abandoned.
Well 30/9-22 was drilled by the Polar Pioneer drilling facility, which will now proceed to production licence 120 in the North Sea to drill development well 34/8-B1 AHT2 on the Visund field, operated by StatoilHydro Petroleum AS.
