  Description

  Type	Text	Date updated
  Transport	The well stream was transported by pipeline to the Ula field for processing. The gas was used for injection in Ula for improved recovery, while the oil was transported by pipeline to the Ekofisk field for further export.	28.02.2023
  Status	Oselvar was shut down in 2018 and the facility was removed in 2022.	28.02.2023
  Recovery strategy	The field was produced by pressure depletion.	28.02.2023
  Development	Oselvar is a field in the southern part of the Norwegian sector in the North Sea, 20 kilometres southwest of the Ula field. The water depth is 70 metres. Oselvar was discovered in 1991, and the plan for development and operation (PDO) was approved in 2009. The development concept was a subsea template with three horizontal production wells tied to Ula. Production started in 2012.	28.02.2023
  Reservoir	Oselvar produced oil and gas from sandstone of Paleocene age in the Forties Formation. The reservoir has a gas cap and lies at a depth of 2,900-3,250 metres.	28.02.2023
