Yes and yes. I did just see a sky news segment from a few weeks ago that apparently, this might literally just be about efficiency and margins. The refineries around the gulf coast are optimized for somewhat heavy crude oil. To maximize efficiency and yield, we’ve been mixing our own light crude oil from western Texas with heavy oil from Canada (Alberta). But apparently, the light crude from Texas is now getting lighter. Between the Canadian trade war, the fact that the only other source…
Oh shit the third reason is that Venezuela has the most crude oil still in the ground, so this is basically like prepping for if Canada runs out or decides to move away from us (which would probably be a terrible idea for them, until they get some pipeline to Asia built). BUT most of these products refined in the gulf coast are actually not motor gas, only 43% is. The remaining products are diesel, jet fuel, and other stuff (e.g. to make plastics). 60% of the motor gas product is exported
So this is also an energy dominance thing, because we need to keep up our gas and diesel (which the EU uses a lot) exports. And it might tie into USD dominance and stability but I’m not entirely sure how that part works. I’ve read a lot of explanations online and am still trying to tie up loose ends
Sorry, screwed up a detail. The overall trend of shale oil in the US seems to be getting somewhat lighter, but it’s mixed and inconsistent. But in Texas specifically, medium density is increasing (so the part about Texas oil getting lighter isn’t true). Nonetheless, we do import heavy oil to meet refining demand. The three places to get that are Canada, Venezuela, and Russia. These refineries were built when heavy oil was abundant and the countries that had it weren’t refining it themselves
