“Proved” = easily recovered. There is likely much more oil reserves waiting to be found and “proved” in the USA, but only with a government that supports developing our petroleum resources.
Much of our oil, including some active wells, falls in the “recoverable” category. That is oil that is recoverable with current technology, vs “Proven” which is economically viable and certain to be produced now. The USA has the most Recoverable oil of any country on earth.
The world has had 20 years of reserves for the last 100 years.
The definition of “proved” reserve is an SEC pseudoscientific definition used in public reports and banking regs.
It’s doesn’t mean “we know there is oil there”. It means “we know there is oil there recoverable at X price and within 5 years where there are actual plans to go get it.” (Nor exactly, but close enough for our purposes here.
The USA has a ridiculous amount of oil we know is there, much of which is not economical at $70 oil. When you go up to $140 oil (which can happen), we’re a massive producer.
