Det norske oljeselskap ASA, operator of production licence 553, has concluded the drilling of wildcat well 34/7-36 S.
The well was drilled about 10 kilometres west of the Visund field in the North Sea. The primary and secondary exploration targets for the well were to prove petroleum in Upper Jurassic reservoir rocks (Intra Draupne and Intra Heather formation sandstones, respectively).
Well 34/7-36 S did not encounter any reservoir in the Draupne formation, while thin reservoir sands of poor quality were encountered in the Heather formation. There are also traces of petroleum in sandstones in the Lista formation from the Palaeocene Age. The well is dry.
Data acquisition and sampling have been carried out.
This is the first exploration well in production licence 553, which was awarded in APA 2009. The well was bored to a vertical depth of 3639 metres below the sea surface and was terminated in the Etive formation from the Middle Jurassic Age. Water depth is 304 metres. The well has been permanently plugged and abandoned.
Well 34/7-36 S was drilled by the Borgland Dolphin, which has now returned to land for its five-year classification.
