Encountering a six m oil-filled Eocene sandstone reservoir, the well confirmed the Heisenberg volume estimate of 24 to 56 million boe with a mean of 37 million boe.
The license partnership, which in addition to DNO Norge AS (49%) includes operator Equinor Energy AS, is studying a tieback of Heisenberg to nearby infrastructure, potentially jointly coordinated with the development of other recent discoveries in this highly prolific area surrounding the Troll and Gjøa production hubs. DNO has a strong area position.
Earlier this year, Cuvette (DNO 20%) marked DNO’s eighth discovery in the area since 2021, following Røver Nord, Kveikje, Ofelia, Røver Sør, Heisenberg, Carmen and Kyrre. Discoveries in the Troll-Gjøa area make up the largest share of DNO’s net contingent resources in the North Sea, which stood at 132 million boe at the end of 2023.
DNO continues to be one of the most active explorers in the North Sea. Last week, the Company commenced drilling operations at Falstaff (DNO 50% and operator) while Ringand (DNO 20%) is expected to be drilled later this fall. In early September, DNO submitted one of the largest applications in the Company’s history for the upcoming APA 2024 licensing round, with awards expected during the first quarter of 2025.
The Angel exploration prospect, which was the main target of the license PL827SB well, was found to be mainly water wet although the well encountered non-commercial volumes of gas.
