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 operations (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. A mobile jack-up rig is utilised for the drilling of production wells. The installation will be supplied with power from shore. A PDO exemption for the Herja discovery and the Hervor prospect was granted in 2017.
ReservoirThe main reservoir contains gas and condensate at high pressure and high temperature (HPHT), and is structurally complex. Three reservoirs are in sandstone of Middle Jurassic age in the Brent Group, at depths of 3,700-4,400 metres. Oil also occurs in the Frigg Formation of Eocene age; the reservoir is at a depth of 1,750 metres and has good quality.
RecoveryThe gas reservoir will be produced by pressure depletion. Oil production from the Eocene reservoir will be supported by natural aquifer drive and gas lift. Produced water will be reinjected.
TransportRich gas will be 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 will be exported via tankers from the FSO.
StatusThe field is under development. The platform jacket was installed on the field in 2014 and the topside modules in 2018. Production is planned to start in mid-2020.
