Aker BP expands Norway growth pipeline with Losgann and Slagugle operatorship deals

Why this news matters:

  • Infrastructure-led development potential: By taking operatorship of the Losgann/Froskelår and Slagugle discoveries, Aker BP can evaluate development concepts that leverage existing hubs, such as Alvheim and Skarv, potentially reducing costs and accelerating time to first production. 

  • Adds to Norway's pipeline of future projects: The deals give Aker BP control of discoveries with further resource upside, including the about 50-MMbbl Slagugle accumulation, supporting continued investment and production opportunities on the Norwegian Continental Shelf.

Aker BP is evaluating development options for the Losgann/Froskelår discovery, including a potential tieback to existing Alvheim-area infrastructure.

Project snapshots:

Losgann/Froskelår

  • Location: Central North Sea, straddling UK-Norway median line
  • Current operator interest being acquired from Apache
  • Potential development concept: Tieback to Alvheim-area infrastructure
  • Strategic value: Cross-border resource with existing export and processing options nearby 

Slagugle

  • Location: Norwegian Sea
  • Aker BP stake after transaction: 51%
  • Partners: ConocoPhillips (29%), INPEX Idemitsu Norge (20%)
  • Estimated recoverable resources: ~50 MMbbl
  • Nearby infrastructure: Heidrun and Skarv field centers
  • Potential development: Subsea tieback concept under evaluation

Aker BP has signed agreements to acquire operatorship of two discoveries in the North Sea and Norwegian Sea, subject to regulatory approvals.

One of the transactions involves taking Apache’s operated interest in the undeveloped Losgann accumulation in the central UK North Sea. This extends across the median line into Norwegian waters where it is known as Froskelår.

Aker BP will seek to establish operatorship on both sides of the field, leading to a potential tieback to offshore infrastructure in the company’s Alvheim area.

Under the second deal with ConocoPhillips Skandinavia, Aker BP will assume operatorship and a 51% stake in the Slagugle area, which covers licenses PL891, PL891B and PL891C in the Norwegian Sea.

Following completion, ConocoPhillips will retain a 29% share, with INPEX Idemitsu Norge holding the remaining 20%.

This would represent a return for Aker BP after exiting the acreage seven years ago. Three wells were drilled in the area between 2020 and 2025, delineating about 50 MMbbl of recoverable oil from the main Slagugle structure.

The partnership has been working on a concept for a subsea development, and the agreement includes plans for additional exploration to increase the resource base ahead of sanctioning a potential project.

Slagugle is 20 km north of the Equinor-operated Heidrun Field and about 270 km north of Kristiansund, and it is also close to Aker BP’s Skarv Field center. 

“ConocoPhillips and its partners have done solid work maturing the area [Slagugle], and by assuming operatorship we can align activity with existing infrastructure and work to establish a competitive basis for a possible development around one of our established hubs,” said CEO Karl Johnny Hersvik.
