Equinor Energy AS, operator of production license 630, has completed the drilling of wildcat wells 35/10-4 S and 35/10-4 A. The wells were drilled about 6.2 mi (10 km) southwest of the Vega field in the northern part of the North Sea. The primary exploration target for well 35/10-4 S was to prove petroleum in Middle and Lower Jurassic reservoir rocks (the Brent group and the Cook formation). The secondary exploration target was to prove hydrocarbons in Upper Jurassic reservoir rocks (the Heather formation), as well as to test the reservoir potential in the Paleocene (Intra Balder sands/the Sele formation).
