Development

Norne is a field in the Norwegian Sea, 80 kilometres north of the Heidrun field. The water depth in the area is 380 metres. Norne was discovered in 1992, and the plan for development and operation (PDO) was approved in 1995. The field has been developed with a production, storage and offloading vessel (FPSO), connected to seven subsea templates. Production started in 1997. The Alve, Urd, Skuld and Marulk fields are tied-back to the Norne FPSO. An amended PDO approved in 2008 included several deposits in the area around the Norne and Urd fields.

Reservoir

Norne produces oil and gas from Jurassic sandstone. Oil is mainly found in the Ile and Tofte Formations, and gas in the Not Formation. The reservoir lies at a depth of 2,500 metres and has good quality.

Recovery

The field is produced by water injection as the drive mechanism. Gas injection ceased in 2005 and all gas is exported.

Transport

The oil is loaded onto tankers for export. Gas export started in 2001 through a dedicated pipeline to the Åsgard field and via Åsgard Transport System (ÅTS) to the Kårstø terminal.

Status

A key element to increasing the recoverable volumes on the Norne field is to evaluate the potential for production enhancement in the Ile Formation. Blowdown of the gas cap in the Not Formation is planned to start in 2019. A recently granted lifetime extension for the Norne FPSO will increase value creation from the Norne field and its satellites.
