$this->bbcode_second_pass_quote('Pops', '')$this->bbcode_second_pass_quote('Anders', 'I')f I remember correctly, someone said that the finding of new reserves peaked in the mid 60s, and after that it has been a steady overall decline in how much reserves are left.
That's close, after discoveries peaked, there has been a decline in discoveries. But like I mentioned, the reserves to production ratio increased until 1987 and has been relatively flat at around 42 years of reserves since.
Of course those are stated reserves, stated by businesses and countries with many reasons to not be entirely forthcoming. Additionally, since they are only estimates of the ultimately recoverable amount of oil in the ground at a certain point in time, reserves can change with changes in technology, the value of the oil, any number of things. What might not have been worth going after at $15 might be perfectly profitable at $50.
Seriously, take a look at the BP charting tool, it's pretty cool and the closest thing we mortals have to getting an idea of the overall picture.
I looked at the BP charting tool. Can be useful.
As for oil reserves, I believe the situation is more like as presented in this chart:
