Aerfugl Oil and Gas Field

Summary Information

• Operator: AkerBP
• Country: Norway
• Location: Norwegian Sea

• Estimated Reserves: The reservoir holds a total of around 300 million barrels of producible oil equivalent
• Production Volume:

Description

• The Ærfugl reservoir (formerly called Snadd) was discovered in 2000 and is located just west of Skarv
• The Ærfugl development is a major subsea project in two phases. Six horizontal gas wells are tied into the existing production vessel (FPSO) on the Skarv field
• The field consists of subsea installations and is enabled by two new technologies in particular:
  • More efficient reservoir drainage through new vertical X-mas trees.
  • Long-distance, electrically heated flow lines to avoid hydrates in the gas pipelines. This technology significantly improves heat efficiency compared with regular technology and enables longer tie-backs.

Contractors

• Subsea 7
  • EPCI contract for an Electrically Heat Traced Flowline (EHTF) for the 21 km tie-back to the Skarv FPSO

History

• 2017 - Subsea 7 awarded EPCI contract for phase II
• 2020 - First production from phase I
• 2021 - First production from phase II

Geology

• The reservoir is located 2,800 meters below the seabed. There is gas in the reservoir, but some oil will also precipitate when it is produced up to atmospheric pressure.
