@Techaltar I mean, it is basically a way to secure the price of oil, for US oil companies. The US have also been shutting down refineries for Canadian heavy crude, IIRC.
This is basically like the consolidation of cigarette companies, after it was clear what the health effects were and they started getting regulated. Oil will keep going up in price, enough to increase profits, while selling less. Many countries will migrate, just because it's too expensive to rely on oil.
