Norwegian state-owned energy company Equinor has received regulatory approval to begin exploration drilling operations in the North Sea offshore Norway using a semi-submersible rig operated by COSL Drilling Europe.

The Norwegian Ocean Industry Authority granted consent for drilling activities in block 34/10. The campaign includes the 34/10-56 exploration well, known as the Rav Beta prospect, within production license 050HS.

The license is valid from 11 April 2012 until 10 September 2031. Equinor holds a 70% operating interest in the license, while Petoro owns the remaining 30%.

The well is located in waters approximately 132 m deep and will be drilled by the COSL Innovator semi-submersible rig.

In August 2023, Equinor awarded the rig a two-year contract scheduled to begin in the second quarter of 2025. The agreement also contains options for up to three additional years.

Built in 2012, the semi-submersible rig is designed for operations in water depths of up to 750 m.

Earlier in January 2026, Equinor reported an oil discovery in the Norwegian Sea using the same rig.
