According to the calculations of "British Petroleum" company, at the current rate of oil extraction the Azeri oilfields will be exhausted in 67 years.

The palm of supremacy belongs to Iraq - its oil will last out 129 years. According to the BP data, Iraq possesses the second in size oil deposits in the world (112.5 billion barrels), yielding only to Saudi Arabia (261.8 billion barrels). Kuwaiti purveyance is estimated to be 98.6, Iranian - 89.7, Russian - 48.6 billion barrels. The present demand for oil of the countries of the world makes some 77 barrels a day.
