world oil reserves left in 2006:

gas and oil are the same material but are in two different forms and sizes of hydrocarbons , both are petroleum and oil is in liquid form with a chain of longer hydrocarbons while gas is in gas form with a chain of reduced or shorter hydrocarbons , when hydrocarbons reduced and get shorter and break away then they give light oil or gas , from organic material oil always produced first and then on higher temperature and pressure it becomes gas , organic material never produce gas directly it always changed first into oil form and then into gas , and where oil is discovered gas is also somewhere near by but not in all cases ,
