Namely, after finding a minor oil and gas discovery, DNO, the oil and gas company, is currently in the process of concluding the drilling of a wildcat well near the Heidrun field in the Norwegian Sea.
Namely, the wildcat well 6507/7-16 S, which is located in production license 888 where DNO is the operator, was aiming to find petroleum in reservoir rocks from the Early and Middle Jurassic Age; the Garn, Ile and Tilje Formations.

This was the first exploration well in production license 888, awarded in APA 2016.
Moreover, the well was drilled to a measured depth of 3238 meters and a vertical depth of 3184 meters below sea level, and it was terminated in the Tilje Formation from the Early Jurassic Age. Water depth at the site is estimated at 341 meters. The well was drilled by the Island Innovator drilling rig, which will now spend time at the shipyard.
It is added that the well will now be permanently plugged and abandoned.
According to the Norwegian Petroleum Directorate (NPD) the well had been drilled almost 4 kilometers west of the Heidrun field in the northern part of the Norwegian Sea and 240 kilometers west of Brønnøysund.
It is said that the well encountered a total gas column of 52 meters in the Garn, Not and Ile Formations, of which 48 meters of sandstone with good to very good reservoir quality. In addition, there is a four-meter thick oil column in the Ile Formation, under the gas column.
Net water-bearing reservoir rocks of almost 75 meters were encountered deeper down in the Ile, Ror and Tilje Formations, mostly with moderate to good reservoir quality. The well was not formation tested, but extensive volumes of data as well as samples have been collected.
The size of the discovery is estimated to be around 1 and 2 million standard cubic meters (Sm3) of recoverable oil equivalents, according to initial calculations. The well results regarding further follow-up of the resource potential in the production license will now be assessed by licensees.
In June, Swedish oil and gas company Lundin Norway, a subsidiary of Lundin Petroleum AB, has made two oil discoveries in exploration wells 16/1-31 S (Jorvik) and 16/1-31 A (Tellus East) on the eastern edge of the Edvard Grieg field in PL338 on the Utsira High, in the North Sea.
