Technical Notes
"Adapted from BP's Statistical Review of World Energy: Definitions and Explanatory Notes."
""
"Definition:"
"Proved natural gas 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. Data are given in million tonnes (metric tons) of oil equivalent (Mtoe)."
""
"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 natural gas estimates have been compiled using a combination of primary official sources and third party data from Cedigaz and the Organization of the Petroleum Exporting Countries (OPEC) Secretariat. 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) of oil equivalent (toe) by WRI using BP's data (provided in trillion cubic metres) and the standard conversion factor of 0.9 million tonnes of oil equivalent per billion cubic metres of natural gas. Conversion to tonnes of oil equivalent facilitates comparisons among different sources of energy. A ""toe"" measures the energy contained in a metric ton (1000 kg) 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 natural gas may vary in quality, converting the estimates into tonnes of oil equivalent using standard conversion factors, rather than country specific conversion factors, introduces a level of uncertainty to the reserve estimates shown here."
""
"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. "
