Here is something else that oil company know and keep secret.

The unexploited oil reserves in the world are at least twice as big as we think.

Not exactly- the term "provable reserves" has a technical meaning, and is usually used with a modifier like "economically recoverable".

Because the public misunderstands that term to mean "absolute amount of supply ever to become available" doesn't make it misleading or even a secret.
