Americas crude: Husky cuts boost Canadian grades.

摘要

Canadian sweet and sour crude differentials rose sharply Monday, with the sweet market still drawing strength from news late last week that Husky Energy had cut rates at its 82,000 b/d bitumen upgrader to 40 of capacity because of snags.The company said that rates would likely be restored by the middle of this week. These problems had "a large part" to do with the rallies seen last week in the sweet market, a market source said.
