Story details
Norwegian oil and gas independent DNO ASA announced a commercial gas and condensate discovery at the Wolverine prospect in production license PL 827 SB in the northern North Sea. Exploration well 35/10-14 was drilled to a total vertical depth of 3,420 meters below sea level by the Deepsea Yantai semi-submersible drilling rig in water depths of 364 meters. Preliminary preliminary volumetric assessments estimate gross recoverable resources between 24 and 48 million barrels of oil equivalent, predominantly consisting of high-calorific natural gas with rich associated condensate yields.
The well encountered a 62-meter gross hydrocarbon column within excellent quality sandstone reservoirs of the Middle Jurassic Brent Group. Comprehensive logging-while-drilling data and wireline formation pressure gradients confirmed fluid contacts and high reservoir permeability exceeding 650 millidarcies. The Wolverine discovery is situated immediately adjacent to DNO's existing Heisenberg discovery hub, allowing the joint venture to fast-track an integrated subsea development scheme tying back into either the Troll C or Gjoa host platforms.
The corporate partnership structure consists of DNO holding a 40 percent operated working interest alongside partners Equinor and Source Energy. The joint venture partners noted that Wolverine represents the fourth consecutive exploration success in the area since 2023, expanding the aggregated resource base of the Heisenberg cluster beyond 130 million barrels of oil equivalent. By leveraging existing host infrastructure with available ullage, unit development costs are modeled below 12 dollars per barrel of oil equivalent.
Executive management stated that exploration efficiency on the Norwegian Continental Shelf continues to deliver superior capital returns due to established subsea pipelines and favorable European gas demand fundamentals. The joint venture plans to conduct comprehensive reservoir simulation modeling over the coming months to finalize subsea manifold specifications and flowline routing. DNO reiterated that short-cycle offshore discoveries with rapid tie-back timelines remain the core pillar of its European growth and energy security strategy.
