Equinor and DNO delineate 2023 oil & gas discovery with appraisal well and sidetrack

Norwegian state-owned energy giant Equinor and compatriot oil and gas operator DNO have completed an appraisal well and sidetrack said to further delineate the 2023 Heisenberg oil and gas discovery in the Norwegian North Sea.

Heisenberg, a new shallow play located in license PL827SB 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).

According to DNO, oil-bearing sands were encountered in the deeper secondary target Hummer.

DNO and operator Equinor are 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 the fast-track development of Heisenberg in coordination with a string of recent discoveries in this area in which DNO has a presence, including last year’s Carmen discovery (30%).

“With recent exploration successes, our North Sea portfolio has tilted towards quality discoveries which we now need to rebalance by adding production,” said DNO’s Executive Chairman Bijan Mossavar-Rahmani.
