2 BP p.l.c., BP Statistical Review of World Energy June 2006, except United States. Oil includes crude
oil, gas condensate, and natural gas liquids. United States oil data, including both crude oil and natural gas liquids,
and United States natural gas data are from the Energy Information Administration, U.S. Crude Oil, Natural Gas, and
Natural Gas Liquids Reserves, 2005 Annual Report, DOE/EIA-0216(2005) (November 2006). BP notes that
"the figure for Canadian oil reserves includes an official estimate of Canadian oil sands 'under active development'." BP
says of its data sources for oil reserves that "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. Likewise for natural gas reserves, BP states that
"the estimates in this table have been compiled using a combination of primary official sources and third-party data from
Cedigaz and the OPEC Secretariat. BP also notes that "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
US 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."
