Serica Energy PLC of London said Erskine field oil and gas production resumed July 27 following clearance of a blockage on a condensate pipeline and also on completion of scheduled maintenance works on the Lomond platform.
Erskine, a high-pressure, high-temperature development, lies in 90 m of water in the UK North Sea.
The pipeline blockage happened earlier this year in the Lomond-to-Everest export line when a pig became lodged due to wax buildup. Crews used pressure pulsing from both ends of the pipeline as well as a wax solvent.
The field then remained shut for a planned 2-month maintenance program on the Lomond platform, which coincided with a planned 1-month shut down for maintenance of export and processing equipment through which Erskine gas is exported.
Following a short period for final clean-up during the first week of August, production from Erskine is projected to build-up rapidly, Serica Energy said.
