Norwegian oil exploration and development firm Det norske oljeselskap has completed the drilling of wildcat well 34/7-36 S in production licence 553.
Det norske has permanently plugged and abandoned the well, which was bored to a vertical depth of 3,639m below the sea surface and terminated in the Etive formation from the Middle Jurassic Age.
The company carried out the drilling with the intention to prove petroleum in Upper Jurassic reservoir rocks that include Intra Draupne and Intra Heather formation sandstones, respectively.
The well, drilled approximately 10km west of the Visund field in the North Sea, did not encounter any reservoir in the Draupne formation.
However, Det norske identified thin reservoir sands of poor-quality in the Heather formation, as well as traces of petroleum in sandstones in the Lista formation from the Palaeocene Age.
The company undertook data acquisition and sampling for the initial exploration well in licence 553, which was awarded in APA 2009.
Det norske operates production licence 553 with a 40% ownership interest.
Svenska Petroleum Exploration holds a 35% stake in the licence and Bayerngas Norge owns the remaining stake.
The licence area consists of parts of block 34/7 and parts of block 34/8.
