Equinor (EQNR) said Thursday it discovered gas at the Gullfaks South field 190 kilometers northwest of Bergen, Norway.

The site production license is held by Equinor, Petoro, and OMV, and holds between 3.3 million and 10.3 million barrels of oil equivalent, the company said.

The exploration well was drilled as a sidetrack during production well operations, Equinor said.
