DNO ASA announced completion of an appraisal well and sidetrack that further delineated the 2023 Heisenberg oil and gas discovery in Norwegian North Sea license PL827SB. Heisenberg, a new shallow play in the northern part of the Norwegian North Sea, is now estimated to hold recoverable volumes in the range of 24 to 56 million barrels of oil equivalent (MMboe) (mean of 37 MMboe). Oil-bearing sands were encountered in a deeper secondary target, Hummer.

The license partnership, which in addition to DNO Norge AS (49 percent) includes operator Equinor Energy AS, is planning a well in the second quarter of this year to explore an additional deep prospect, Angel, while delineating Heisenberg towards the west. Surrounded by major North Sea hubs Troll B, Kvitebjørn and Gjøa (the first two operated by Equinor), Heisenberg lies within tieback range of these hosts. Studies are underway for fast-track development of Heisenberg in coordination with a string of recent discoveries in this area in which DNO has a significant presence, including in last year?s Carmen discovery (30%).
