Total Norge, operator of production licence 618, is in the process of completing the drilling of wildcat well 1/5-5. The well is dry.
The well was drilled about 40 kilometres northwest of the Ekofisk field and 320 kilometres southwest of Stavanger.
The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (Ula formation). The secondary exploration target was to prove petroleum in Upper Triassic reservoir rocks (Skagerrak formation).
The well encountered about 80-metre thick sandstone in the Ula formation with moderate to poor reservoir quality. The reservoir only contains traces of gas. The well is classified as dry.
Data acquisition was carried out.
This is the first exploration well in production licence 618. The licence was awarded in APA 2011.
Well 1/5-5 was drilled to a vertical depth of 5942 metres below the sea surface and was terminated in the Bryne formation in the Middle Jurassic.
Water depth at the site is 70 metres. The well will now be plugged and abandoned. Well 1/5-5 was drilled with the Maersk Gallant drilling rig.
