Most I know of are west of NO, in the "Golden Triangle".
Someone more knowledgeable than I can elaborate or refute that matter, but we're not all dead yet. We're just squoze harder.
Yes, most of the Louisiana refineries are west of New Orleans. Mississippi has several away from the coast, as does Alabama. There are many refineries across Texas and Okalhoma, California has some, and there are some in places that you would never think of.
The big questions are how long the LOOP will be offline and whether there are problems bringing in the offshore oil. Most of the platforms themselves should be coming back by the end of the week if they can get the crews together. (Most were west of the storm's path).
I'm still predicting a sharp break in oil prices, although the timing will be delayed by this storm.
