How much oil is left on Earth?

It is estimated that there are at least 1.7 trillion barrels of oil, and possibly as many as 6.5 trillion barrels, accessible with current technology.  Humankind has burned through about 1 trillion barrels to date, and at the current rate of consumption, there would be enough oil to support demand for another 160 years. Estimate of total petroleum resources in the ground range from 14 to 24 trillion barrels, the majority of which is believed to be in North America.
