16/12/2009 Statoil Petroleum AS, operator of production licence 159 B, has completed the drilling of wildcat well 6507/3-8, which proved gas. The discovery was made about two kilometres southwest of the Norne field.
The objective of the well was to prove petroleum in the Fangst and Båt group in Middle to Lower Jurassic reservoir rocks. The well proved a 142-metre gas column in the Fangst and Båt group.
The size of the discovery is estimated at between 1.3 and 1.5 billion standard cubic metres (Sm3) of recoverable gas. The well encountered rocks of the expected thickness and good reservoir quality. The well was not formation-tested, but extensive data acquisition and sampling have been carried out.
The licensees in production licence 159 B will consider producing the discovery via the Norne field.
This is the second well in production licence 159 B, which was carved out from production licence 159 in 2004. PL 159 was awarded in licensing round 12 B in 1989.
The well was drilled to a total depth of 2968 metres below the sea surface, and was terminated in the Tilje formation in the Lower Jurassic.
The water depth at the site is 378 metres. The well will now be permanently plugged and abandoned.
Well 6507/3-8 was drilled by the Ocean Vanguard drilling facility, which will now proceed to production licence 057 in the North Sea to drill wildcat well 34/4-12S, where Statoil Petroleum AS is the operator.
