Ivar Aasen produces through a conventional fixed platform, with oil and gas exported via a pipeline to Lundin's Edvard Grieg complex for processing. Depending on reservoir performance, the facilities could operate for 20 years. This year Aker BP plans to submit development plans for three projects: one involves expansion of the Valhall field in the North Sea (Valhall West Flank). The other two are subsea tiebacks - Snadd to the Skarv FPSO in the Norwegian Sea, and Storlakken to the North Sea Alvheim floater. In addition, the company has contracted the Maersk Invincible to drill three new wells this year from the Valhall Injection platform. Other plans include introducing gas-lift at the Tambar field and preparing the Ula facilities to handle production from the Centrica-operated Oda field development.
