The prospect is located 15 kilometres west of the Solveig field and 220 kilometres west of Stavanger.
This is the first exploration well drilled in production licence 979, which was awarded through APA (awards in pre-defined areas) in 2018.
The well was drilled by the Scarabeo 8 drilling rig.
In recent years, exploration activity in the central part of the North Sea has been characterised by minor discoveries close to existing infrastructure. The area is defined as mature. Aker BP and Equinor have been the dominant exploration companies in this area.
Geological details
The objective of the well was to prove hydrocarbons from the Middle Jurassic in the Hugin and Sleipner formations.
The secondary exploration target was to prove a reservoir and hydrocarbons in the Draupne and Heather formations.
The well encountered the Vestland Group near the primary exploration target. It has a thickness of 97 metres, 8 metres of which were sandstone with moderate to poor reservoir quality. Weak hydrocarbon indicators were recorded.
Near the secondary exploration target, the well encountered 191 metres of the Draupne Formation and 104 metres of the Heather Formation. Reservoir rocks were not proven in these two formations.
Well 15/6-17 was drilled to a vertical depth of 3704 metres below sea level, and was terminated in the Smith Bank Formation in the Triassic. Data acquisition was carried out, which included securing a 54-metre-long core in the Vestland Group.
Water depth at the site is 102 metres, and the well has been permanently plugged and abandoned.
