Offshore Norway Wildcat Hits 160-m Gas Column in Brent Group
Drilling Activity Details
Drilling Activity Summary
Description
Stavanger-based Equinor has completed wildcat, #30/2-5 S, which is south of Kvitebjørn Field in the Norwegian North Sea. The objective of the well was to prove petroleum in reservoir rocks from the Middle Jurassic Age (the Brent Group). The venture encountered a gas column of about 160 m in Brent Group (Tarbert, Ness, Etive and Rannoch), of which 60 m make up an effective sandstone reservoir. Ness has 30 m of sandstone with poor-to-moderate reservoir quality, while Etive has 15 m of sandstone, primarily of moderate quality. The Tarbert has 10 m of sandstone with poor-to-moderate reservoir quality, and Rannoch has 5 m of poor quality sandstone. Preliminary estimates indicate that the discovery between 3 and 10 MMcm of recoverable oil equivalents. No formation-testing was conducted, but volumes of data have been acquired, and samples have been taken and additional assessment is planned. This is the first exploration well in production license 878. The well was drilled to 4,390 m and area water depth is 142 m and bottomed in Drake (early Jurassic).
