Latest North Sea Sverdrup oil well gives reservoir details
The Bredford Dolphin has completed the latest appraisal well on the Johan Sverdrup field in Norwegian North Sea license PL501.
Well 16/3-7 was drilled at the structure’ssouth-eastern flank. Operator Lundin Norway’saims were to determine depth to the top of the reservoir, reservoir thickness, and the oil-water contact.
The well encountered 50-m (164-ft) gross reservoir thickness, slightly deeper than expected, comprising 14 m (46 ft) of late Jurassic sandstone and 36 m (118 ft) of Permian dolomitic carbonates.
Although the oil/water contact was not proven, oil and water were sampled in the uppermost part of the reservoir at 1,925 m (6,315 ft) below mean sea level, suggesting a contact point close to this level.
The rig will next drill appraisal well 16/5-5 in PL410, also for Lundin.
