Dry well near the Visund field in the North Sea

Equinor Energy AS, operator of production licence 120, has completed the drilling of wildcat well 34/8-19 S.

The well was drilled on the northern side of the Visund field in the northern part of the North Sea.

The objective of the well was to prove petroleum in Lower Jurassic reservoir rocks in the Cook formation, and in Upper Triassic reservoir rocks in the Statfjord group.

Well 34/8-19 S encountered about 90-m-thick rocks in the Cook formation, of which 22 m were effective reservoir consisting of sandstone with mainly moderate to good reservoir quality. Due to technical drilling challenges, the well was not drilled to the second exploration target in the Statfjord group. Data acquisition was carried out. The well is dry.

This is the 24th exploration well in production licence 120, which was awarded in licensing round 10-A in 1985. 

Well 34/8-19 S was drilled to a measured depth of 6100 m, a vertical depth of 3137 m below the sea surface and was terminated in the Amundsen formation in Lower Jurassic.

Water depth is 378 m. The well will be permanently plugged and abandoned.

Well 34/8-19 S was drilled by Deep Sea Atlantic, which will now proceed to drill development well 34/8-D-4 AH on Visund Nord in the North Sea, where Equinor Energy AS is the operator.
