When will the oil end?

According to data from the website The Balance, if current global demand for oil remains constant there will only be enough oil reserves for an estimated 47 years.  Theoretically, this is many years off, but considering that five of the top 10 counties based on oil reserve figures are in political conflict with the US, it means this time-frame is unstable.  So even with years of global reserves left, it is possible that available supply will not be able to support demand causing gasoline and oil product prices to rise as the supply dwindles.

From the website The World Counts, when the amount of oil on earth will be depleted based on recognized (proven) current supply and global demand.
