DNO has made a significant gas condensate discovery at its Norma prospect in the Norwegian North Sea license PL984. 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 km south of the Alvheim hub, Norma is situated in an area with extensive infrastructure in the central part of the North Sea, with tieback options offering potential routes to commercialization.

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-m hydrocarbon column in a 20-m gross reservoir section in Jurassic sandstones.

DNO is calling the discovery 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.

DNO was awarded an interest in PL984 in 2019 through its wholly owned subsidiary DNO Norge AS. The company holds a 30% operating interest. The other partners in the license are Source Energy AS, Equinor Energy AS, Vår Energi ASA (20% each), and Aker BP ASA (10%).
