Equinor Energy AS, operator of production licence 923, has concluded the drilling of wildcat well 31/2-23 S, the Norwegian Petroleum Directorate said on Thursday.
The well was drilled about 3 kilometres west of the Troll field in the North Sea and about 120 kilometres northwest of Bergen.
The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks in the Brent Group.
The well encountered the Brent Group with a thickness of around 135 metres, including sandstone layers of around 80 metres with good reservoir quality.
The well is dry and data acquisition has been carried out, the Norwegian Petroleum Directorate stated.
This is the fifth exploration well in production licence 923, which was awarded in APA 2017.
Well 31/2-23 S was drilled to a vertical depth of 2333 metres below sea level and was terminated in the Drake Formation in the Lower Jurassic.
Water depth at the site is 343 metres. The well has been permanently plugged and abandoned.
Well 31/2-23 S was drilled by Deepsea Stavanger, which is now drilling wildcat well 31/2-24 in the same production licence as 31/2-23 S.
