DevelopmentMartin Linge is a field near the border to the UK sector in the northern part of the North Sea, 42 kilometres west of the Oseberg field. The water depth is 115 metres. Martin Linge was discovered in 1978, and the plan for development and operation (PDO) was approved in 2012. The development concept is a fully integrated fixed production platform and a floating storage and offloading unit (FSO) for oil storage. The installation is supplied with power from shore. A PDO exemption for the Herja discovery and the Hervor prospect was granted in 2017.
ReservoirMartin Linge produces mainly gas and condensate from sandstone of Middle Jurassic age in the Brent Group. The reservoirs are structurally complex with high pressure and high temperature (HPHT) at depths of 3,700-4,400 metres. In addition, there is oil in the Frigg Formation of Eocene age. The Frigg reservoir is at a depth of 1,750 metres and has good quality.
RecoveryThe gas is produced by pressure depletion. Oil from the Frigg reservoir is produced by natural aquifer drive and gas lift. Some produced water is reinjected.
TransportRich gas is transported to the Frigg UK pipeline (FUKA), and on to the Shell-Esso Gas and Liquid (SEGAL) terminal at St Fergus in the UK. Oil and condensate are exported via tankers from the FSO.
StatusThe platform jacket was installed on the field in 2014, and the topside modules in 2018. Production started in June 2021.
