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. The production started in 1997 and stopped temporarily in 2016 when the Njord A platform was shut down and towed to land for reinforcement and modifications. An amended PDO for the upgrading was approved in 2017. Production from the Njord field resumed at the end of 2022. The fields Hyme, Bauge and Fenja are tied-back to Njord.

Reservoir

Njord produces oil from Jurassic sandstone in the Tilje and Ile Formations. The field has a complicated fault pattern with only partial communication between the segments. The reservoir quality varies in the different reservoir zones. The reservoir depth is 2850 metres.

Recovery strategy

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

Drilling of new wells started in August 2023. Njord is planned to receive power from shore via the Draugen platform in a few years and thus be partially electrified.
