Can you explain a bit about khurais. I don't know much about the field except for the vanadium.

The fact that KSA is expending so much effort to develop a field with basically unsellable oil speak volumes in itself. Just about any combination of other choices if they existed make more sense. Unless of course production has peaked.

It is manifa that has the vanadium, this is probably what sa meant when they said they had no buyers for their oil last spring. Khurais produced at one time something over 100k/d, then trickled down and was abandoned. They have great hopes with, I think, a water flood, but 1.2Mb/d seems wildly optimistic... imo more likely they might get back to their former peak for a while.
