Forties Pipeline shutdown

London, 12 December 2017 - Serica Energy plc (AIM: SQZ) has been informed by the operator of the Erskine field that the Forties Pipeline System ("FPS"), the export route for Erskine condensate, will be unavailable, potentially for some weeks, while the FPS owner plans and implements repairs to a hairline crack in the onshore section of the pipeline.

During this period the Erskine field, along with the other fields that use the pipeline, which include the BKR Assets1, will be unable to produce. This will impact Serica's production guidance for the year to 31 December 2017, which has been revised to approximately 2,000 boe per day net to Serica from the Erskine field.

Further updates will be provided as and when more information becomes available.
