23/04/2010 Centrica Resources (Norge) AS, operator of production licence 433, has completed the drilling of wildcat well 6506/9-2 S in the Norwegian Sea. The well proved gas/condensate.
The well was drilled about 10 kilometres north of the Smørbukk gas and condensate discovery and 250 kilometres northwest of Kristiansund.
The objective of the well was to prove petroleum in Middle to Late Jurassic rocks (the Garn, Ile, Tofte and Tilje formations).
The well proved gas/condensate in both the Garn and Ile formations, while the Tofte and Tilje formations are probably filled with water. Preliminary estimates indicate the size of the discovery at between 3 and 15 million standard cubic metres (Sm³) of recoverable oil equivalents.
Extensive data acquisition and sampling have been carried out in both the Garn and Ile formations. A more extensive analysis of the results will be needed before a decision can be made regarding delineation and development of the discovery.
The well is the first exploration well in production licence 433. (Link to fact page) The licence was awarded in connection with APA 2006.
Well 6506/9-2 S was drilled to a vertical depth of 4736 metres and terminated in the Åre formation in the Lower Jurassic.
Water depth at the site is 281 metres. The well will now be permanently plugged and abandoned. Well 6506/9-2 was drilled by the West Alpha drilling facility, which will now proceed to production licence 470 in the Norwegian Sea to drill wildcat well 6407/12-3 where Centrica is also the operator.
