|
Notes: Proved reserves of oil - Generally taken to be those quantities that 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 22.0
billion barrels for oil |
|
|
|
|
|
sands
under 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. |
