Det norske oljeselskap ASA, operator of production licence 482, is about to complete drilling of wildcat well 6508/1-2. The well proved oil and gas. The well was drilled about ten kilometres south of the Norne field in the Norwegian Sea.
The objective of the well was to prove petroleum in Early Jurassic reservoir rocks (the Tilje/Åre formations).
The well proved gas and oil in the Tilje/Åre formations with reservoir properties as expected. An 18-metre gas column and 23-metre oil column were identified.
The preliminary size of the discovery has been estimated at about one million standard cubic metres of recoverable oil equivalents. Further studies and exploration of the further potential can clarify whether the discovery is commercially viable.
The well was not formation tested, but extensive data acquisition and sampling have been carried out.
This is the first exploration well in production licence 482. The licence was awarded in APA 2007.
The well was drilled to a vertical depth of 1770 metres below the surface and terminated in Early Jurassic rocks. The water depth is 395 metres. The well will now be permanently plugged and abandoned.
Well 6508/1-2 was drilled by the Aker Barents drilling facility, which will now proceed to production licence 530 in the Barents Sea to drill wildcat well 7124/4-1S, where GDF SUEZ Norge AS is the operator.
