How long will the world's oil reserves last?

It depends on where you live such as with Australia (my home), it is estimated 100-350 years, but since we have a huge natural gas tank off the north-west coast of WA, and will soon be moving onto nuclear power within 15 years, we may never run out, but this is unlikely since we do make alot of money for selling it to China.How long will the world's oil reserves last?
Every petroleum engineering professor tells me the same thing.








We don't know.How long will the world's oil reserves last?
not long enough
Probably another two weeks.
There are alot of estimates that put the worlds reserves around 30 years.


These estimates usually don't take into account new technology that helps us to recover more oil from conventional sources, and also new technology that makes production from unconventional sources possible.





Also there are some resources that can't be exploited in the next 30 years. Canadas oil sand for instance are so large, that the investment in infrastructure that would be needed to get at the oil isn't possible to build in the next 30 years.





So I would take 30 years as a base and then add 20% for new technology. Then I would realize that even if we get down to 10% of the oil left in the world we are effectively out of oil because we use so much just to get it out of the ground.





So my best guess is 30 years, with Canada and Venezula still having oil sands left. Thats it though, then we are all living on hydrogen power.
