About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Sygna is a field in the Tampen area in the northern North Sea, just northeast of the Statfjord Nord field. The water depth is 300 metres. Sygna was discovered in 1996, and the plan for development and operation (PDO) was approved in 1999. The field has been developed with one subsea template with four well slots, connected to the Statfjord C facility. Three production wells have been drilled from the template. A long-reach water injection well was drilled from the Statfjord Nord template. The production started in 2000.
- Reservoir
- Sygna produces oil from Middle Jurassic sandstone in the Brent Group. The reservoir is at a depth of 2650 metres and has good quality.
- Recovery strategy
- The field is produced by pressure maintenance from water injection.
- Transport
- The well stream is transported by pipeline to the Statfjord C facility for processing, storage and export. Sygna, Statfjord Nord og Statfjord Øst have a shared process module on Statfjord C. The oil is loaded onto tankers and the gas is exported through Tampen Link and the Far North Liquids and Gas System (FLAGS) pipeline to the UK.
- Status
- The production from Sygna is stable, and the strategy is to keep the reservoir pressure constant by water injection.
