Dry well near the Frøy field in the North Sea
Det norske oljeselskap ASA, operator of production licence 414, is in the process of concluding the drilling of wildcat well 25/6-4 S.
The well is being drilled in the central part of the North Sea,
about 20 km southeast of the Frøy field and 37 km northeast of the
Heimdal field.
The primary exploration target for the well was to prove
petroleum in Paleocene reservoir rocks (the Hermod formation). The
secondary exploration target was to prove petroleum in Middle
Jurassic reservoir rocks (the Brent group). The well encountered
reservoir rocks with good reservoir quality, as expected. Data
acquisition and sampling have been carried out, but both levels are
water-bearing and the well has been classified as dry.
This is the first exploration well in production licence 414,
which was awarded in APA 2006. Wildcat well 25/6-4 S was drilled to
a vertical depth of 2738 metres below the sea surface, and was
terminated in Middle Jurassic rocks (the Dunlin group). Water depth
at the site is 114 metres. The well will now be permanently plugged
and abandoned.
The well was drilled by the Songa Delta drilling facility, which
will proceed to production licence 418 in the northern part of the
North Sea to drill wildcat well 35/9-7, where Wintershall Norge ASA
is the operator.
