    Development
    Aasta Hansteen is a field in the northern part of the Norwegian Sea, 120 kilometres northwest of the Norne field. The water depth is 1270 metres. Aasta Hansteen was discovered in 1997, and the plan for development and production (PDO) was approved in 2013. The field initially comprised three separate accumulations: Luva, Haklang and Snefrid Sør. A new accumulation was discovered in 2015, Snefrid Nord. The field is developed with a SPAR (Single Point Anchor Reservoir) platform moored to the seabed. The development includes in addition two subsea templates with four slots each and two subsea templates with one slot each (satellites). The templates are tied-back to the platform through pipelines and steel catenary risers. Aasta Hansteen was granted a PDO exemption for the development Snefrid Nord in 2017. The production started in 2018.
    14.12.2023
    Reservoir
    The main reservoirs contain gas in Upper Cretaceous sandstone in the Nise Formation, at a depth of 3000 metres. The reservoir quality is good.
    28.02.2023
    Recovery strategy
    The field is produced by pressure depletion and natural aquifer drive.
    28.02.2023
    Transport
    Gas from Aasta Hansteen is transported via the Polarled pipeline to the terminal at Nyhamna. Light oil is offloaded to shuttle tankers and transported to the market.
    28.02.2023
    Status
    The production is at the end of the plateau phase. It is planned to produce the field with low-pressure production in the future. The Irpa field is under construction as a subsea tied-back to Aasta Hansteen.
