The return to service of BP's BP.L Whiting, Indiana refinery has been delayed, industry sources said.
BP started the planned turnaround work at its 435,000 barrel-per-day refinery in late September. The refinery began restarting units involved in the turnaround in early November. A source said at least two of the units have experienced startup delays. The units are expected to be back online this week, the source added.
