I have been thinking that sour oil is behind this "market is well supplied" line that the Saudis have been using. After all, it's not their fault if they're offering crap and no one is buying, right?

I've raised this issue a couple of times here and it never seems to get answered. If they have crummy oil and no one can refine it, then both sides are right:

1. They have oil but no buyers
2. They don't have oil for people who want it.

These high prices are for light sweet crude. What is the spread today between WTI and the worst Saudi tar?
