A friend of mine told me that she owns shares in several oil wells in Kansas and Oklahoma. They were originally bought by her father back in the 1950s. She told me that her father was a Korean War veteran and they were presented some opportunities to purchase these shares in lieu of some other kind of money the government was going to give them. I don't know what it was, she didn't say.
But she did say that for basically her entire life (after her father passed away) she's been receiving checks from the oil companies. Usually very small like $40 a month. But sometimes, when USA gets into an oil war and they start pumping their own domestic oil, she gets monthly checks for ~$1,500.
I would be curious to know how much crude USA buys from Canada instead of pumping it domestically. I guess all the domestic oil is part of the strategic oil reserves though.
