I think what distracted me with the shear size of those ciggie packet calculations was that although the numbers are massive, its usually a few cents, or bucks, a barrel industry. It's massive pie for sure, but it feeds a lot of mouths. So usually the people eating that pie only get a spoon or two each. And now along comes Trump, and he does not have a spoon. He arrives with a bucket excavator to scoop up his pie.
And, I hate to defend big oil here, it's such a complex industry that I can barely get my head around how it works. The oil companies will want a high price of course, but too high and it will impact sales. Too low and many wells will not be economically viable.
And on wells being economically viable, I looked up Venezuela oil, that Trump now has a massive stake in.
"The $100 per barrel threshold cited by energy analysts represents the approximate crude oil price level necessary to make large portions of Venezuela’s heaviest reserves economically viable for commercial development, meaning that at current price levels around $60 per barrel, significant portions of the declared reserve base remain stranded assets lacking commercial viability"
I have no idea of the accuracy of that, but a large amount of VZ reserves need a $100 price to be viable. And aint it a massive coincidence, that the guy who seized VZ oil just put 20% on the price of 25% of the world supply of oil.
Edit. Add source for VZ oil data.
