About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- 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. A PDO exemption for the development of Snefrid Nord was granted in 2017. 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. The production started in 2018.
- 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.
- Recovery strategy
- The field is produced by pressure depletion and natural aquifer drive.
- 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.
- Status
- The production went off plateau in 2024 and low pressure production has started. The Irpa field is under construction as a subsea tie-back to Aasta Hansteen.
