US independent ConocoPhillips has come up dry with an exploration well on the Hasselbaink prospect in the North Sea, off Norway.

The Norwegian Petroleum Directorate (NPD) confirmed Wednesday the 25/7-9S exploration well, in production licence 917, had terminated in the Sele formation after reaching a total depth of 1955 metres.

The well intersected two thin sandstone layers of about one metre in the Hordaland group, with very good reservoir properties and traces of petroleum.

However, the NPD said the probe had been classified as a dry well and permanently plugged and abandoned.

The well was drilled about 7 kilometres north-west of the Balder field, with the objective of proving petroleum in the Eocene reservoir rocks of the Hordaland group.

ConocoPhillips used the semi-submersible Leiv Eiriksson to drill the well, the same rig it used to drill the 25/7-8 S well on the Ennisberg prospect last month which resulted in a minor gas discovery.

Both wells lie in PL 917, which ConocoPhillips operates with a 40% stake on behalf of partners Lundin Petroleum, Suncor Energy and Vaar Energi which each hold a 20% share.
