Serica Energy Provides Erskine Field Update

Serica Energy plc, an independent oil and gas company with production, development and exploration licence interests in the UK North Sea and exploration interests in Ireland and Namibia, hereby provides the following update on the interruption to production at the Erskine field.

As announced on 22 January 2018, during cleaning operations a blockage occurred on the Lomond to Everest pipeline, through which Erskine condensate is exported to market. This caused Erskine field production to be shut-in. The blockage is believed to be due to a deposit of wax in the pipeline. Chrysaor Limited, the Operator of this pipeline, has been attempting to resolve this problem but has been unable to achieve a significant breakthrough. Therefore, the decision has been made to cease clearance operations and instead concentrate on accelerating the pipeline bypass programme and on running an extended maintenance programme.

Plans to lay a new 26km length of pipeline to bypass the zone affected by wax deposits have been progressing. An order was placed with the pipeline manufacturers in February and a route survey has been completed. Approvals for the work from the authorities are expected in July and construction is scheduled for August, with production restart expected in September. Once laid, a proactive cleaning programme will commence in order to maintain the pipeline through high frequency pigging.

As a significant maintenance programme was already planned for this summer, the Lomond operator has taken this opportunity to extend this, performing further, pre-emptive maintenance on the platform whilst it is hydrocarbon free. From 1 May, work will commence to reduce the backlog of maintenance work as well as perform inspections and replace and repair key equipment. This work is designed to improve future performance of the facilities, reducing production interruptions and reducing the length of future shut-downs in the coming years.
