(the popularity of this decision reminds me of the way all the power companies added gas-fired plants at the same time, all based on the same assumption of $2.50 NG for the long run: it may make sense for an individual refiner or power plant, but when everybody does it, there can be unintended side effects.) this is not just in the US but also a lot of Asian refining capacity additions. there is a huge refinery demand for sweet crude, production of which may already have peaked. at the same time, the crude additions by the Saudis are too sour for the same refineries. so this sour crude goes for much cheaper. this is a great situation for the sour refiners--plenty of supply of their input product, and a dearth of supply for their competitors (sweet refineries). since the end product must be priced economically for the sweet refiners, the sour refiners make a killing. i think the peak is already in for sweet crude. if so, the sour refiners will have a great advantage in the years ahead.
