Technical Notes
"Adapted from BP's Statistical Review of World Energy: Definitions and Explanatory Notes."
""
"Definition:"
"Proved oil reserves are 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. Oil includes gas condensate and natural gas liquids as well as crude oil. Data are given in million tonnes (metric tons)."
""
"Years Covered and Frequency of Update:"
"This dataset contains reserve estimates for 1980-2006. BP publishes updated and revised data in their Statistical Review of World Energy every June."
""
"Methodology: "
"Proved oil reserves estimates have been compiled using a combination of primary official sources, third party data from the Organization of the Petroleum Exporting Countries (OPEC) Secretariat, World Oil, Oil & Gas Journal and an independent estimate of Russian reserves based on information in the public domain. The reserves figures shown do not necessarily meet the definitions, guidelines and practices used for determining proved reserves at the company level, for instance those published by the United States Securities and Exchange Commission or recommended for the purposes of UK SORP, nor do they necessarily represent BP's view of proved reserves by country."
""
"The estimates shown here were converted to tonnes (metric tons) by WRI using BP's data (provided in thousand million barrels) and the standard conversion factor of 0.1364 tonnes per barrel, based on worldwide average gravity of crude oil. World totals include estimates for countries not included here."

"For more information and to view the original dataset, please refer to BP's  Statistical Review of World Energy 2007."
""
"Data Reliability: "
"Since energy sources such as oil may vary in quality, converting the estimates into tonnes using standard conversion factors, rather than country specific conversion factors, introduces a level of uncertainty to the reserve estimates shown here."
""
"All numbers are, at best, informed estimates. Within the broad concept of oil 'reserves' there are several key distinctions: ultimately recoverable resource, proved, probable and possible reserves and oil in place. The data shown here are proved reserves. Every effort is made to come up with a consistent series for reserves based on a common definition, however, in reality, different countries use different methodologies and the data have varying levels of reliability."
