Equinor Energy AS will plug North Sea wells in production license (PL) 090. Wells 35/11-25 S and 35/11-25 A, the 19th and 20th exploration wells in the license, are classified as dry.
The wells were drilled by the Deepsea Atlantic about 7 km west of Fram field in the northern North Sea, and 125 km north-west of Bergen, in 352 m of water.
Well 35/11-25 S was drilled to vertical and measured depths of 2,854 m and 3,157 m below sea level, respectively, and was terminated in the Heather formation from the Late Jurassic. The objective was to prove petroleum in rocks from the Late Jurassic (Sognefjord formation equivalent). The well encountered about 65 m of intra-Heather formation sandstone (Sognefjord formation equivalent) of good to very good reservoir quality.
Well 35/11-25 A was drilled to vertical and measured depths of 3,208 m and 3,711 m below sea level, respectively, and was terminated in the Oseberg formation from the Middle Jurassic. The objective was to prove petroleum in the Etive formation from the Middle Jurassic. The well encountered about 55 m of sandstone of moderate reservoir quality.
The wells were classified as dry. They were not formation-tested, but extensive data acquisition and sampling were performed.
Deepsea Atlantic will now drill wildcat well 31/11-1 S in PL 785 S in the central part of the North Sea.
Equinor is operator at PL 090 (45%) with partners Idemitsu Petroleum Norge AS (15%), Neptune Energy Norge AS (15%), and Vår Energi AS (25%).
