About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- 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 4-slot subsea template tied-back to the Sleipner A facility. The production started in 2002.
- Reservoir
- The Sigyn field produces gas and condensate from two separate accumulations, Sigyn West and Sigyn East. Sigyn West contains rich gas and condensate, while Sigyn East contains light oil. The main reservoirs are in Triassic sandstone of the Skagerrak Formation, at a depth of 2700 metres. There are also thin reservoir sandstone layers in the Upper Jurassic intra-Draupne Formation.
- Recovery strategy
- Sigyn East is produced with pressure support from gas injection and Sigyn West is produced by pressure depletion.
- Transport
- The well stream is sent through two pipelines to the Sleipner A facility. Sales gas is exported from Sleipner A via Gassled (Area D). Unstable oil is exported by pipeline to the Kårstø terminal for final processing.
- Status
- The field is in its late tail production phase. An infill well was put on production on Sigyn East in 2022, and the existing producer was converted to a gas injector. There has only been production from Sigyn East after the well on Sigyn West ceased producing in early 2024. A new infill well is planned to be drilled on Sigyn West in 2026. The well shall produce from both the Triassic and Jurassic reservoirs.
