13/01/2009 Press release 5/2009:StatoilHydro ASA, operator of production licence 128, has concluded wildcat well 6608/10-12 and is in the process of concluding appraisal well 6608/10-12 A. Both wells encountered oil in the Åre formation.
The purpose of wildcat well 6608/10-12 was to prove petroleum in reservoir rocks from the Early Jurassic Age, and an oil discovery was recently made in the well. The discovery is located about 17 kilometres north-northeast of the Norne field.
The purpose of the subsequent appraisal well 6608/10-12 A was to encounter the oil-water contact, and to determine the extent of the discovery.
The wells proved oil in Early Jurassic rocks (the Åre formation), and the oil-water contact was encountered in the appraisal well. A 110-metre oil column was encountered. The preliminary estimate of proven recoverable resources is between 4 and 8 million Sm3 of oil. Neither of the wells was production-tested, but extensive data collection and sampling have been carried out. Consideration will be given to developing the discovery in connection with the Norne field.
Wildcat well 6608/10-12 and appraisal well 6608/10-12 A are the 22nd and 23rd exploration wells in production licence 128. The licence was awarded in licensing round 10B in 1986.
The wildcat well was drilled to a vertical depth of 3158 metres below the sea surface. The appraisal well was drilled to a vertical depth of 2931 metres below the sea surface. Both wells were concluded in rocks from the Early Jurassic Age (the Åre formation).
Water depth at the site is 334 metres. The wells will be permanently plugged and abandoned.
The wells were drilled by the semi-submersible drilling facility Ocean Vanguard, which will now proceed to production licence 376 in the North Sea to drill wildcat well 35/6-1 S, where StatoilHydro ASA is the operator.
