    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.
    13.12.2023
    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 reservoirs are in Triassic sandstone of the Skagerrak Formation, at a depth of 2700 metres.
    09.12.2023
    Recovery strategy
    Sigyn East is produced with pressure support from gas injection and Sigyn West is produced by pressure depletion.
    28.02.2023
    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.
    28.02.2023
    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. Production is limited by well performance and available flowlines. Currently, there is only production from Sigyn East. Production from Sigyn West is limited because the available flowlines are used to inject gas and produce oil from Sigyn East.
