Aker BP makes oil discovery in Yggdrasil area
Aker BP has completed its Omega Alfa exploration campaign in the Norwegian North Sea, resulting in a significant oil discovery that adds substantial new resources to the Yggdrasil area. The recoverable volume is estimated at 96–134 million barrels of oil equivalent (boe).
The campaign had five exploration targets – Omega, Alfa, Alfa South, Sigma NE, and Pi – through a multilateral well located west of Yggdrasil. In July, Aker BP preliminarily reported a discovery of 20–40 million boe from two of these targets. Following the completion of the campaign, the combined recoverable volumes have increased to 96–134 million boe.
Drilling operations began in early May using the Deepsea Stavanger rig. Over a three-month period, the team drilled a total of 45,000 m, including 40,000 m in reservoir sections. This included the three longest well branches ever drilled on the Norwegian continental shelf, with the longest branch reaching 10,666 m.
The horizontal drilling method enabled the collection of an unprecedented amount of high-quality reservoir data. This has significantly reduced subsurface uncertainty and allows us to rapidly advance into concept studies to determine the optimal tie-back solution to Yggdrasil.
Yggdrasil is the largest field development project currently underway on the Norwegian continental shelf. The Omega Alfa campaign was conducted across production licencses 873, 873 B, and 1249, all operated by Aker BP.
