We also have coal and natural gas, which increases the supply to last at least 200 years.
As mentioned, this is only proven reserves. We probably have 3-5 times as much in the ground. Vast areas of the earth have not been explored for oil, and extraction technology continues to improve.
As others have mentioned, there are vast supplies of energy from other sources available. Battery tech continues to improve, making electric transport more efficient, and solar power more reliable.

Yep. So far fracking has mainly been commercial in the US. That’s probably not due to unique geology, but due to skill and need. When it’s time to unlock the source rock in the Middle East and Russia, both the oil and technology to get it will be there.
