Equinor Reports Gas Discovery of Up to 10.3 Million Barrels of Oil Equivalent

Equinor and partners Petoro and OMV discovered gas at Norway’s Gullfaks South field, adding recoverable resources to the producing satellite field in the North Sea.

The discovery is 190 kilometers northwest of Bergen within the Gullfaks production license. The estimated volume ranges from 0.5 million to 1.6 million standard cubic meters of oil equivalent.

The Askeladden rig drilled the exploration well as a sidetrack during a production-well operation. The well is formally named 34/10-D-4 BH and is listed as an observation well drilled from Sept. 3 to Sept. 16, 2026.

Gullfaks South is a producing satellite field with subsea installations connected to the Gullfaks A and Gullfaks C platforms. Production began in October 1998.

Gullfaks A began production in December 1986, followed by Gullfaks B in 1988 and Gullfaks C in 1989. Gas from the field moves through Statpipe to the Kårstø processing facility.

“It is very positive that it is possible to make discoveries of this size with such cost-effective exploration wells,” said Gunnar Egge, Equinor’s vice president for the Gullfaks field.

Equinor operates the license with a 51% interest. Petoro holds 30%, while OMV holds 19%.
