DNO make a discovery in the Norwegian North Sea

Preliminary evaluation of the discovery indicates gross recoverable resources in the range of 25-130 million boe on a P90-P10 basis, with a mean of 70 million boe, in a Jurassic reservoir zone with high quality sandstones. Located 20 km northwest of the Balder hub and 30 kmsouth of the Alvheim hub, Norma is situated in an area with extensive infrastructure in the central part of the North Sea, with tie-back options offering potential routes to commercialisation.

Also within the same license, DNO has identified additional exploration prospects that have been considerably de-risked by the Norma results.

“Coming on the heels of our six Troll-Gjøa area discoveries since 2021, three of which were made this year including Carmen, Heisenberg and Røver Sør, Norma opens up an exciting new play for DNO in the North Sea,” said Executive Chairman Bijan Mossavar-Rahmani. “At the risk of hoodooing our crack explorationists, the string of recent discoveries validates DNO’s offshore Norway exploration strategy,” he added.

Drilled to a vertical depth of 4800 m with the Deepsea Yantai drilling rig, Norma is DNO’s first operated high-pressure high-temperature exploration well. At 4650 m, the discovery well encountered a 16-meter hydrocarbon column in a 20-meter gross reservoir section in Jurassic sandstones. Several gas condensate samples were collected in the reservoir. In addition, a water sample was acquired. A bypass core of 33.7 m was secured and an extensive data and sampling program conducted.

This discovery is considered a play-opener for the deep turbiditic sands in this area given the exceptionally good reservoir quality encountered. Plans are underway to further delineate the discovery and the upside potential in the license. Before further appraisal drilling, improved seismic imaging and remapping will be undertaken to identify an optimal location for the next well.

Even with the additional extensive data collection protocols, the Norma well is expected to be finished 15 days ahead of plan and at a cost eight percent below budget. Plug and abandonment operations have commenced this week.
