About the field

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

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. The production started in 2012.
Reservoir
Oselvar produced oil and gas from sandstone of Paleocene age in the Forties Formation. The reservoir is at a depth of 2900-3250 metres.
Recovery strategy
The field was produced by pressure depletion.
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.
Status
Oselvar was shut down in 2018, and the facility was removed in 2022.
