Erskine Operational Update

London, 23 August 2016 - Serica Energy plc (AIM: SQZ) provides the following operations update:

As previously announced, production from the Erskine field (Serica 18%) restarted on 27th July following a prolonged period to clear a blocked pipeline and undertake planned maintenance on the Lomond platform which provides treatment and export facilities to Erskine.

In line with earlier statements, Erskine production was built up for a short period to flush the Lomond/Everest condensate export line and establish full flow through the system before being temporarily suspended for final clean-up operations and for re-commissioning of Lomond platform facilities to be completed. Initial field production rates of over 4,300 boepd net to Serica were achieved in this period, supporting the capability of the Erskine reservoir and Erskine wells to deliver at high rates.

Shell as operator of the Lomond platform, has now advised that re-commissioning of the Lomond export facilities, which was expected to take one week, has taken longer than projected and that further work is required on the main Erskine condensate export pump, located on Lomond, before it can be brought fully on-line. As a result, re-commencement of full, continuous production of Erskine has been delayed.

A further operational update will be released by the Company when advice has been received from Shell that these re-commissioning issues have been resolved. The Company has been advised by Shell that this is likely to take several more days.
