Using
BP's statistical review for 2004, the charts below represent the
rate of depletion of existing reserves for oil and gas if no new
sources for petroleum are found. This second petroleum depletion
case simply adds oil and gas reserves and oil and gas production
into combined barrel equivalent numbers, treating them as if they
were the same in terms of removing them from the ground. When gas
or oil within the countries is depleted, production continues as
if there were no change in the reserve. The regions are seperated
into the rate of depletion for OPEC, which represents 64% of currently
known reserves, and the rate for other major producers, which represent
an additional 28% of the world's reserves.
