    Development
    Ivar Aasen is a field in the northern part of the North Sea, 30 kilometres south of the Grane and Balder fields. The water depth is 110 metres. Ivar Aasen was discovered in 2008, and the plan for development and operation (PDO) was approved in 2013. The development comprises a production, drilling and quarters (PDQ) platform with a steel jacket and a separate jack-up rig for drilling and completion. The production started in 2016. The platform is equipped for tie-in of a subsea template planned for the development of the Hanz field, and for possible development of other nearby discoveries. First stage processing is carried out on the Ivar Aasen platform, and the partly processed fluids are transported to the Edvard Grieg platform for final processing and export. Ivar Aasen is supplied with power from shore since 2023.

    Reservoir
    Ivar Aasen produces oil from sandstone reservoirs. The field consists of the 16/1-9 Ivar Aasen discovery and the small 16/1-7 (West Cable) discovery. The reservoir in the Ivar Aasen discovery consists of fluvial sandstone of Late Triassic to Middle Jurassic age in the Skagerrak and Sleipner Formations and shallow marine sandstone in the Middle Jurassic Hugin Formation. The reservoir is at a depth of 2400 metres. It is compartmentalised and has moderate to good quality. Parts of the reservoir have an overlying gas cap. The reservoir in the West Cable discovery is in fluvial sandstone in the Middle Jurassic Sleipner Formation. It is at a depth of 2950 metres and has moderate quality.
    13.12.2023
    Recovery strategy
    The Ivar Aasen reservoir is produced by pressure support from water injection. The West Cable reservoir is produced by pressure depletion.
    28.02.2023
    Transport
    Oil and gas are transported to the Edvard Grieg platform for final processing. The oil is exported by pipeline to the Grane Oil Pipeline, which is connected to the Sture terminal. The gas is exported in a separate pipeline to the Scottish Area Gas Evacuation (SAGE) system in the UK.
    28.02.2023
    Status
    Since production start-up, additional injection and production wells have been drilled. Ivar Aasen production is on decline. The Hanz field and the discovery 16/1-29 S Symra are under development and will be tied-back to Ivar Aasen.
