The well was drilled about 7 km southeast of the Oseberg C platform in the northern North Sea and 140 km west of Bergen.
The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks (Intra Heather Formation sandstones).
The well encountered poorly developed sandstones in the Intra Heather Formation with poor reservoir quality and no traces of petroleum. The well is classified as dry.
Data has been collected.
