According to Bloomberg, ConocoPhillips reported that a power dip led to flaring at its Wood River refinery in Illinois, according to a filing with state regulators. The flaring of sulfur dioxide was caused by the power drop in a distilling wet gas compressor. Outages can increase prices for refined products as companies turn to spot markets to help them meet supply contracts. Operational disruptions can also depress prices for crude oil as less feedstock is used. The Wood River refinery is part of a joint venture with Alberta oil-sands producer Cenovus Energy designed to increase the amount of heavy Canadian crude processed in ConocoPhillips’s Wood River and Borger, Texas, refineries.
