Using Deepsea Aberdeen semi-submersible rig, the appraisal well 6406/3-10 A has been drilled in production licence (PL) 836 S.
The firm now estimates that the size of the previously discovered recoverable resources in the Garn and Tilje Formations to range between 40 to 84 million barrels of oil equivalent (MMboe).
Wintershall also identified approximately 260m gas column in the Åre Formation, which was not identified in the original discovery well. This formation is estimated to hold 13MMboe to 56MMboe.
In April 2020, the company initially estimated the Bergknapp discovery to hold recoverable reserves between 26MMboe and 97MMboe.
The appraisal well 6406/3-10 A, which was drilled to a vertical depth of 4,854m and a measured depth of 5,160m below sea level, was terminated in the Åre Formation from the Early Jurassic.
The Bergknapp discovery is located approximately 8km west of the Wintershall Dea-operated Maria oil field.

We will now work closely with our partners to bring the project to the final investment decision and successfully drive the development of the prospect.”
