Wintershall Dea, together with its partners Petoro, Aker BP and PGNIG, has completed an appraisal well in the Adriana gas and condensate discovery.
The well has resulted into an upward revision in the estimated recoverable volumes from the discovery in the Norwegian Sea.
Drilled using the Transocean Norge rig, the appraisal well encountered high-quality reservoirs in the primary target within the Cretaceous Lysing Formation.
The consortium is now evaluating potential development options for the Adriana discovery, which was made in 2021.
As per the initial estimates, recoverable volumes at Adriana were 19–31 million barrels of oil equivalent (boe).
The new appraisal results have led to a revised estimate of 28–43 million barrels.
The Adriana discovery is part of a multi-level discovery that includes the Dvalin North gas field.
Dvalin North is currently being developed as a subsea tie-back to the Heidrun platform via the Wintershall Dea-operated Dvalin field.
Located approximately 270km north of Kristiansund, the Adriana discovery is positioned in the Haltenbanken area of the Norwegian Sea, in proximity to other fields such as Dvalin, Aerfugl and Skarv.
Following the appraisal activities at Adriana, the Transocean Norge rig has been relocated to the Maria field, operated by Wintershall Dea, to commence drilling operations related to the Maria Phase 2 development.
Wintershall Dea Norway VP of exploration & subsurface Roy Davies said: “Our exploration strategy, as a subsea specialist, focuses on investing in areas close to existing infrastructure, where we already have a sound understanding of the geology and potential development options.
“This improves the possibility of fast-tracking discoveries into new subsea developments. The promising results from the Adriana appraisal well put us in a strong position to consider potential development strategies for this discovery.”
In December 2023, Wintershall Dea’s owners, BASF and LetterOne, reached an agreement to sell the company's upstream oil and gas assets to Harbour Energy for $11.2bn (€10.36bn).
The assets included in the deal are located in Algeria, Argentina, Denmark, Egypt, Germany, Libya, Mexico and Norway.
