Western Canada Select, a heavy oil blend from Alberta, weakened after a hydrotreater fire at BP Plc’s Whiting, Indiana, refinery threatened to curb crude demand.
Planned repairs on the unit were suspended, a person with knowledge of the situation said. The person, who asked not to be identified because the information is private, didn’t know if the suspension of the work and an investigation into the fire would delay the completion of the maintenance.
