Equinor Energy AS collected data from a recent Norwegian Sea exploration well before plugging. The well is dry, without traces of petroleum.
Well 6407/9-13—the first in production license 1060—was drilled by the West Hercules drilling rig about 148 km north of Kristiansund and about 8 km northwest of Draugen field to a vertical depth of 2,319 m subsea. It was terminated in the Ror formation from the Early Jurassic. Water depth at the site is 270 m.
The primary exploration target was to prove petroleum in reservoir rocks from the Late Jurassic (the Rogn and Melke formation), while the secondary exploration target was to prove petroleum in reservoir rocks from the Middle Jurassic (the Garn and Ile formation).
In the primary target in the Melke formation, sandstone rocks totaling 27 m were encountered, with very good reservoir quality. The well did not encounter reservoir rocks belonging to the Rogn formation.
In the secondary exploration target, the well encountered sandstone rocks totaling 76 m in the Garn formation and sandstone rocks totaling 17 m in the Ile formation. The reservoir rocks in both formations are of good to very good reservoir quality.
The drilling rig will now proceed to Canada for new assignments.
