Development

Njord is a field in the Norwegian Sea, 30 kilometres west of the Draugen field. The water depth is 330 metres. The Njord field was discovered in 1986, and the plan for development and operation (PDO) was approved in 1995. Njord is developed with a floating steel platform unit, Njord A, containing drilling and processing facilities, and a storage vessel, Njord Bravo. Production started in 1997. An amended PDO was approved in 2017. The Hyme field is tied to the Njord facility.

Reservoir

The pressure decline in the reservoir has been less than anticipated. This has resulted in increased recoverable volumes compared to PDO estimates. Installation of the Åsgard subsea gas compressor has accelerated and prolonged gas production from the field. A stable supply of gas with low CO2 content from the Mikkel field is important for dilution of gas with high CO2 content from the Kristin field in the Åsgard Transport System.

Recovery

Initial production strategy was gas injection for pressure support in parts of the reservoir and pressure depletion in the rest of the reservoir. After gas export started in 2007, only minor volumes of gas have been injected. Due to the complex reservoir with many faults, the field has a relatively low recovery factor.

Transport

Produced oil is transported by pipeline to the storage vessel Njord Bravo, and further by tankers to the market. Gas from the field is exported through a 40-kilometre pipeline connected to the Åsgard Transport System (ÅTS) and further to the Kårstø terminal.

Status

Production from the Njord field and its satellite field Hyme was temporarily shut down in 2016 because of Njord A structural integrity issues. To extend the lifetime of the fields, Njord A and Njord Bravo were towed to land for upgrades and modifications. Production from the Njord and Hyme fields is expected to resume in late 2021. The Bauge and Fenja fields are under development and will also be tied to Njord.
