Shell says boosting output at Canadian refinery

CALGARY, Alberta, May 15 (Reuters) - Royal Dutch Shell Plc (RDSa.L: Quote, Profile, Research, Stock Buzz) said on Thursday it is increasing production at its 72,000 barrel a day Sarnia, Ontario, refinery after a week of unplanned maintenance on one of the units.

The plant, the smallest of Shell's three refineries in Canada, should be back at full rates soon, spokesman John Peck said, without elaborating.

Peck declined to say which unit was down for repairs or by how much output was reduced during the work. (Reporting by Jeffrey Jones; Editing by Peter Galloway)
