Shell makes minor gas discovery in the Norwegian Sea
STAVANGER -- A/S Norske Shell, operator of production licence 255, is about to complete drilling of wildcat well 6406/9-3.
The well was drilled about 15 kilometres northwest of the Njord field and 7 kilometres southeast of the 6406/9-1 Linnorm gas discovery, in the southern part of the Norwegian Sea. The primary and secondary exploration targets for the well were to prove petroleum in Middle to Lower Jurassic reservoir rocks (Ile, Tofte and Tilje formations).
The well encountered the Ile, Tofte and Tilje formations with variable reservoir quality. A thin gas column was encountered in the Ile formation, but the size of the discovery is not commercially interesting. The other reservoir rocks were tight or aquiferous.
The well was not formation tested, but data acquisition and sampling have been carried out.
6406/9-3 is the fifth exploration well in production licence 255. The licence was awarded in the 16th licensing round in 2000.
The well was drilled down to a vertical depth of 5095 metres below the sea surface, and was terminated in the Tilje formation in Lower Jurassic.
Water depth is 298 metres. The well will be permanently plugged and abandoned.
6406/9-3 was drilled by the Transocean Barents drilling facility, which will now drill wildcat well 35/9-9 in production licence 153 in the North Sea, where GDF SUEZ E&P Norge AS is the operator.
