The real reserves of petroleum still in the ground are subject to some uncertainty, and this is probably due to commercial secrecy to a large extent. The generally accepted view is that there is enough for another 40 years from known fields. There is also a lot in tar sands and oil shale which can be exploited and probably will be as known fields get depleted. The big unknown must be how much remains to be discovered, and exploration is ongoing in many parts of the world.
