PRODUCTION FROM THE FIELD

Høykontrast Modus

Status

The Sigyn field is in the tail phase, but production has been higher than expected. In 2017, a lifetime extension was granted until 2022. Gas injection is being evaluated in Sigyn West and Sigyn East to increase recovery.

Transport

The well stream is controlled from Sleipner Øst and is sent through two pipelines to the Sleipner A facility. Sales gas is exported from Sleipner A via Gassled (Area D) to the market, while unstable condensate is transported in a dedicated pipeline to the Kårstø terminal.

Development

Sigyn is a field in the central part of the North Sea, 12 kilometres southeast of the Sleipner Øst field. The water depth is 70 metres. Sigyn was discovered in 1982, and the plan for development and operation (PDO) was approved in 2001. The field is developed with a subsea template tied-back to Sleipner Øst. Production started in 2002.

Reservoir

The Sigyn field is in the late tail production phase. Production is cyclic and limited by capacity available at Sleipner A and decreasing reservoir pressure. Gas injection to increase recovery is being evaluated.

Recovery

The field is produced by pressure depletion.
