Moscow, November 7 - Neftegaz.RU. Aker BP and its partners have drilled a dry well in the Yggdrasil area in the North Sea.
Well 30/11-16 S (Natrudstilen) was drilled in production licence 873, just over 1 kilometre east of Fulla and 155 kilometres west of Bergen. Well 30/11-16 S was drilled by the Deepsea Stavanger rig.
Production licence 873 was awarded in 2017 (APA 2016). This is the eighth exploration well drilled within the licence area. There is plenty of activity in the area around production licence 873; Yggdrasil is being developed, and in August, Aker BP and its partners made a substantial oil discovery in the Omega Alfa exploration campaign. This campaign covered three production licences in the area.
Geological information
The objective of the well was to prove petroleum in the Natrudstilen prospect in the Tarbert Formation in the Middle Jurassic.
The well encountered the Tarbert Formation with a thickness of about 350 metres, 197 metres of which were sandstone with moderate to poor reservoir quality. The well is classified as dry with hydrocarbon shows.
Hydrocarbon shows were observed in the Hardråde Formation and Tryggvason Formation in the Upper Cretaceous.
Data was collected, including pressure points in the upper part of the Tarbert Formation.
Well 30/11-16 S was drilled to a vertical depth of 4327 metres below sea level and was terminated in the Tarbert Formation in the Middle Jurassic. The water depth is 112 m, and the well has now been permanently plugged and abandoned.
