Exxon Mobil Corp. said on Nov. 9 it had isolated a unit at its 270,000 bbl/d Fawley oil refinery in southern England following an incident that led to gas flaring on Nov. 8.

The refinery remains operational, it added.

"Our own onsite teams safely and effectively addressed the matter, isolating the unit from operation. There were no injuries and there was no fire," a spokesperson said.

"Fawley remains operational and there is no impact on fuel supply to customers."

The company did not say which unit was affected.
