  Type	Text	Date updated
  Development	Øst Frigg is a field in the central part of the North Sea, four kilometres east of the Frigg field. The water depth is 100 metres. Øst Frigg was discovered in 1973, and the plan for development and operation (PDO) was approved in 1984. The field was developed with two subsea templates and a central manifold station tied to the Frigg field. The production started in 1988.	09.12.2023
  Reservoir	Øst Frigg produced gas from sandstone of Eocene age in the Frigg Formation. The reservoir is at a depth of 1900 metres and has excellent quality. The field contains two separate structures, which are part of the same pressure system as the Frigg field.	09.12.2023
  Recovery strategy	The field was produced by pressure depletion.	28.02.2023
  Transport	Gas was transported in a pipeline from the manifold to the Frigg field (TCP2) for processing, and further via pipeline the Shell-Esso Gas and Liquids (SEGAL) terminal at St Fergus in the UK.	28.02.2023
  Status	Øst Frigg was shut down in 1997, and the subsea templates were removed in 2001. The ongoing development of the Fulla field also includes a redevelopment of Øst Frigg. Appraisal wells were drilled on the Øst Frigg field in 2022 and 2023.	09.12.2023
