Equinor announces oil discovery related to Oseberg Vestflanken

Equinor has, on behalf of the Oseberg partners, made a profitable oil discovery related to Oseberg Vestflanken. The well was drilled by the Askepott rig and the discovery will soon be put on stream via the new, unmanned and remote-operated H platform on the Oseberg field.

Included in the Oseberg Vestflanken phase 2 project, the exploration extension well 30/6-H-9-T4 proved a 112 m oil column in a segment that has not been tested before. Oil was proven in the Statfjord formation in southern parts of the Alpha structure on Oseberg.

Reservoir characteristics are excellent with high oil saturation. Recoverable resources are estimated at 22 million bbl. The partners will consider water injection to further increase recoverable volumes. 

Gunnar Nakken serves as the Senior Vice president for the Operations West Cluster of Equinor.

“This discovery improves the Oseberg Vestflanken resource base. It can be put on stream with limited investments and adds significant value to the partnership,” Gunnar Nakken, Senior Vice President for the Operations West Cluster of Equinor, said. “We are combining drilling of exploration and production wells to achieve highly profitable exploration wells at low cost.”

“Discoveries as these underline the importance of near-field exploration,” Mr Nakken added. “Our ambition is to maintain profitable production from the Norwegian continental shelf (NCS) for several decades. A major contribution will come from wells that are drilled at low cost and close to existing infrastructure.”

Equinor’s NCS roadmap focuses on developing our key hubs for sustainable and long-term value creation. The Oseberg area is such a hub, offering a good resource base and possible future tie-ins from fields in the area.

The unmanned and remote-operated wellhead platform Oseberg H came on stream less than a year ago. The well was drilled by the Oseberg license’s new Cat J-rig Askepott on its first assignments on Vestflanken.

“Having played a key role in the Norwegian oil adventure, Oseberg will continue to be important to us for a long time going forward. We are therefore pleased to see that recent investments in the area prove to be good business for both partners and society,” Mr Nakken said.

At the end of 2017, Oseberg was the third largest oil producer on the NCS having produced around 2.9 billion bbl. Original development plans were based on an oil production of around 2 billion bbl. Current expectations are that 3.1 billion bbl will be produced during the lifetime of the field.
