Serica Energy announced that oil and gas production resumed from the Erskine field, located in the Central North Sea.
Production at had been shut down following a pipeline blockage and scheduled maintenance work on the Lomond platform in the UK Continental Shelf.
“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,” Serica Chairman Tony Craven Walker, said.
Production Resumes at North Sea Erskine Field
The pipeline blockage occurred earlier this year in the Lomond to Everest condensate export line and was caused when a Pig became lodged in the pipeline, during Pigging operations, due to the build-up of wax, the company informed.
The problem has since been solved using clearance procedures, which included pressure pulsing using diesel from both ends of the pipeline as well as injecting a wax solvent.
As well as this, the field remained shut-in due to a two-month maintenance programme on the Lomond platform, starting in late May.
The work involved the maintenance of the CATS gas export and processing facilities through which Erskine gas is exported.
“Since Serica acquired its interest in the Erskine field in June 2015, it has made a significant contribution to cash flow and profits. This has equipped us to withstand issues such as this shutdown,” Walker added.
Erskine To Reach Full Production in August
After the completion of the maintenance programme, condensate flow started in mid-July from the Lomond field to flush the export line.
The production of higher volumes from Erskine started on July 27 and is expected to ramp up to full production during August.
Another programme to improve production efficiency and ensure continuous export availability is expected to be implemented soon to prevent the wax build-up from occurring again.
This will occur after full production has been re-established and will entail the completion of a full integrity survey of export infrastructure to determine the potential to extend the operational life of the infrastructure.
