01/09/2011 OMV Norway AS, operator of production licence 471, is in the process of completing the drilling of wildcat well 6407/5-2 S. The well has been drilled about 10 kilometres southwest of the Mikkel field in the Norwegian Sea.
The primary exploration target for the well was to prove petroleum in Upper Cretaceous reservoir rocks (the Lysing formation). The secondary exploration target was to prove petroleum in Lower to Middle Jurassic reservoir rocks (the Garn, Ile, Tofte and Tilje formations).
The well encountered the Lysing formation with dense reservoir rocks. In the secondary target, gas was encountered in the Garn formation with reservoir rocks and reservoir quality as expected, and in addition gas was encountered in the Upper Jurassic (the Rogn formation). In total, there is a 40-metre gas column in the Rogn and Garn formation. The size of the discovery is not financially viable.
Data acquisition and sampling have been carried out.
The well is the first exploration well in production licence 471. The licence was awarded in APA 2007.
The well was drilled to a vertical depth of 3359 metres below sea level, and was terminated in the Tilje formation in Lower Jurassic rocks.
Water depth at the site is 230 metres. The well will now be permanently plugged and abandoned.
Well 6407/5-2 S was drilled by the Borgland Dolphin drilling facility, which will now proceed to production licence 559 in the Norwegian Sea to drill wildcat well 6608/11-7 S where Rocksource ASA is the operator.
