It really doesn't matter whether we export more oil than we import. Oil prices are set by a global market. Oil produced in Texas, Oklahoma and North Dakota is sold to the highest bidder at a price set by the global market. It is not reserved for us, or Canada, or out allies. If the price of oil on a given day is $100 our oil sells for $100 dollars a barrel. What happened in 2020 was decreased demand for oil due to the pandemic. As economies rebounded, demand increased and prices rose. Now, with Russian oil being off the market prices are even higher.
