Equinor Energy AS, operator of production licence 923, has concluded the drilling of wildcat well 31/2-23 S.

Dry well near the Troll field in the North Sea

The well was drilled about 3 km west of the Troll field in the North Sea and about 120 km northwest of Bergen, Norway.

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 m, including sandstone layers of around 80 m with good reservoir quality. The well is dry and data acquisition has been carried out.

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 m below sea level and was terminated in the Drake Formation in the Lower Jurassic.

Water depth at the site is 343 m. 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.
