Development
Tune is a field in the northern part of the North Sea, ten kilometres west of the Oseberg field. The water depth is 95 metres. Tune was discovered in 1995, and the plan for development and operation (PDO) was approved in 1999. The field has been developed with a subsea template and a satellite well tied to the Oseberg Field Centre. Production started in 2002. A PDO exemption was granted for the development of the northern part of the field in 2004. A similar exemption was granted for the southern part of the field in 2005.Reservoir
Tune produces gas and some condensate mainly from Middle Jurassic sandstone in the Tarbert Formation (Brent Group). The reservoir is at a depth of 3400 metres and divided into several inclined fault blocks . Another reservoir is in the underlying Statfjord Formation.Recovery strategy
The field is produced by pressure depletion. Low-pressure production has been implemented.Transport
The well stream from Tune is transported in pipelines to the Oseberg Field Centre, where the condensate is separated and transported to the Sture terminal through the Oseberg Transport System (OTS). Gas from Tune is injected in the Oseberg field, while the licensees can export a corresponding volume of sales gas from Oseberg.Status
The Tune field is in its tail production phase and produces cyclically. The main challenges for Tune are old infrastructure and low reservoir pressure. There has been no production since mid-2022 due to well integrity issues.ACCRUED INVESTMENTS IN NOMINAL NOK
