Vår Energi has found oil and gas at its appraisal well 7122/7-7 S on the Goliat oil field in the Barents Sea offshore Norway. Its priority goal was to delineate the Goliat field by proving additional resources in Lower Jurassic and Upper Triassic reservoir rocks and secondly to prove petroleum in reservoir rocks in the Upper Triassic (the Snadd formation).
Mainly, Vår Energi was established on December 2018, after the merge between Point Resources and Eni Norge. The company drilled the well about 2 kilometers south of the Goliat floating production, storage and offloading installation (FPSO), 90 kilometers northwest of Hammerfest.

The well found a total oil and gas column of 18 meters in the Tubåen formation. Effective reservoir rocks amount to 13 meters, of which 8 meters with gas and 5 meters with oil in sandstone with very good reservoir quality.
Also, the oil/water contact was only encountered at 1145 meters.
In the Fruholmen formation, the well encountered a total oil column of 33 meters, of which 15 meters of effective reservoir rocks in sandstone of good reservoir quality.
NPD has said that 25 meters of the Snadd formation were drilled, and the formation proved to be aquiferous and of variable reservoir quality.
The recoverable resources are estimated to be from 0.7 to 2.2 million standard cubic meters oil. Total volumes in place are estimated to approximately reach 2 to 7 Mscm. Vår Energi will consider tying the additional resources to the Goliat FPSO in the near future.
According to the operator, even before the drilling started, resource estimates for Goliat had already rose to 31.5 Mscm (198 Mbbl), from 28.0 million Mscm (176 Mbbl) at the time of the PDO. Goliat West will further increase the resource estimates on Goliat.
According to Kristin Kragseth, CEO in Vår Energi
The Goliat West discovery will add to the profitability of Goliat and provides evidence for the future potential for this part of the Barents Sea.
Moreover, Denis Palermo, VP Exploration in Vår Energi, added that the Goliat West appraisal well is a successful outcome of Vår Energi’s near-field exploration strategy.
Vår Energi operates PL 229 and the oil-producing Goliat field with an interest of 65 percent, together with Equinor Energy AS as partner.
Concluding, the well was drilled by Seadrill’s West Hercules semi-submersible drilling rig, which will now drill wildcat well 7132/2-1 in production license 857 in the Barents Sea, where Equinor Energy AS is the operator.
