The wells were drilled about 7 km west of the Fram field in the northern North Sea and 125 km north-west of Bergen.
The objective of well 35/11-25 S was to prove petroleum in rocks from the Late Jurassic (Sognefjord Formation equivalent). The objective of well 35/11-25 A was to prove petroleum in the Etive Formation from the Middle Jurassic.
Well 35/11-25 S encountered about 65 m of intra-Heather Formation sandstone (Sognefjord Formation equivalent) of good to very good reservoir quality. The well is dry. Well 35/11-25 A encountered about 55 m of sandstone of moderate reservoir quality in the Etive Formation. The well is dry.
The wells were not formation-tested, but extensive data acquisition and sampling were performed.
These are the 19th and 20th exploration wells in production licence 090. This licence was awarded in the 8th licensing round in 1984.
Well 35/11-25 S was drilled to respective vertical and measured depths of 2854 and 3157 m below sea level, and was terminated in the Heather Formation from the Late Jurassic.
Well 35/11-25 A was drilled to respective vertical and measured depths of 3208 and 3711 m below sea level, and was terminated in the Oseberg Formation from the Middle Jurassic.
Water depth at the site is 352 m. The wells have been permanently plugged and abandoned.
The wells were drilled by the Deepsea Atlantic drilling facility, which is now moving on to drill wildcat well 31/11-1 S in production licence 785 S in the central part of the North Sea, where Equinor Energy AS is the operator.
