Huh, this is something that our ‘tin-foil’ colleges haven’t gotten around to yet. In the meantime the only factors I can think of are transportation costs and regional political expectations. Anyone else have ideas?
I'm not complaining, though, gasoline is a mite cheaper here than on the coast.
Much of the crude oil from the North Slope is exported to Japan and broadly affects the Asian market. The loss of a major nuclear facility in Japan and the improving Asian economies must inevitably cause an increased demand for North Slope crude oil. In addition, the alternative source of crude for Asia — the Mid East — is cast into doubt by the ongoing unrest in the Persian Gulf.
When you see them starting to truck Cushing crude to Tulsa and subsequently barge it to the Gulf, you'll know the spread(s) will be narrowing substantially in short order.
