(Reuters) – Royal Dutch Shell (RDSa.L) reported restarting an unspecified unit at its Scotford, Alberta, facility on Sunday, according to a community alerting system.
There will be intermittent flaring for the next 12 hours, the message added.
The Scotford facility houses a 100,000 barrel-per-day refinery and a 255,000 barrel-per-day oil sands upgrader.
