The pipeline blockage, which occurred earlier this year in the Lomond to Everest condensate export line, was caused when a foam cleaning device known as a pig became lodged in the pipeline due to a build-up of wax.
Successful clearance procedures included pressure pulsing using diesel from both ends of the pipeline and latterly the injection of a wax solvent.
The field then remained shut for a planned 8-week maintenance programme on the Lomond platform.
Tony Craven Walker, Chairman, Serica Energy, commented: “Since Serica acquired its interest in the Erskine field in June 2015, it has made a significant contribution to cashflow and profits. This has equipped us to withstand issues such as this shutdown.
“Now that production has resumed we expect this strong performance to continue as we seek to add further interests to increase shareholder value at a time of low oil and gas prices.”
“Our aim is to deliver value from Serica’s strong portfolio of exploration and production assets in Europe and Africa, together with the pursuit of new opportunities both in the UK and overseas. “
