Proved reserves of oil: Generally taken

to be those quantities which geological

and engineering information indicates

with reasonable certainty can be

recovered in the future from known

reservoirs under existing economic

and operating conditions.

.

Reserves-to-production (R/P) ratio:

If the reserves remaining at the end

of any year are divided by the

production in that year, the result

is the length of time that those

remaining reserves would last if

production were to continue at that

rate.

.

Source of data: The estimates in

this table have been compiled using

a combination of primary official

sources, third-party data from the

OPEC Secretariat, World Oil,

Oil & Gas Journal and an independent

estimate of Russian reserves based

on information in the public domain.

Canadian proved reserves include

an official estimate of 21.0 billion

barrels for oil sands ùnder active

development`. Reserves include

gas condensate and natural gas

liquids (NGLs) as well as crude oil.

Annual changes and shares of total

are calculated using thousand million

barrels figures.
