Equinor Energy AS has permanently plugged a dry Norwegian Sea wildcat well and will proceed with drilling of a second area well, the Norwegian Petroleum Directorate said in a June 15 release.
Well 6305/5-C-3 H was drilled about 137 km west-northwest of Kristiansund by the Transocean Barents drilling rig to a vertical depth of 4,320 m subsea. It was terminated in the Shetland Group from the Turonian age. Water depth at the site is 925 m.
The objective was to prove petroleum in reservoir rocks in the Lange formation and the Lysing formation in the Upper Cretaceous (Turonian and Coniacian Ages, respectively). The well encountered mainly siltstone with thin layers of sandstone and dolomite stringers in both formations.
Data acquisition has been carried out. Attempts to collect pressure data and sampling indicate that the formations have low permeability and are partly tight.
The exploration well was the sixth in production license 209.
The rig will now continue in the same location to drill production well 6305/5-C-3 AH (OGJ Online, Jan. 27, 2022).
Equinor is operator of the license with 40% interest. Partners are Petoro AS 35%, A/S Norske Shell 15%, and Vår Energi ASA 10%.
