Adding to the other comments that point out opportunity to sell overseas is too tempting.

Also despite being a net exporter, some places are likely to import.

In the southeast, prices have gone up, but not as much as the West Coast. So much logistics to feed the pipelines that would be so tricky to get into ships, that is not worth doing it. So places where boats play a large role in oil logistics, well those places are subject to global market conditions more.
