— 'Remaining established reserves', less reserves 'under active development'.
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.
