1 Proved reserves are estimated quantities that analysis of geologic and engineering data demonstrates with reasonable certainty are recoverable
under existing economic and operating conditions.
2 BP p.l.c., BP Statistical Review of World Energy June 2008, 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, 2006 Annual Report, DOE/EIA-0216(2007) 
(November 2007).  BP notes that for oil its "Canadian proved reserves include an official estimate of 21.0 billion barrels for oil sands 'under 
active development'."  BP does not include but separately reports an additional 152.2 billion barrels of Canadian oil sands defined as 
"'remaining established reserves', less reserves '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."  
3 PennWell Corporation, Oil & Gas Journal, Vol. 105.48 (December 24, 2007), except United States.  Oil includes crude oil and condensate.  Data for the United  
States are from the Energy Information Administration, U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves, 
2006 Annual Report, DOE/EIA-0216(2007) (November 2007).  Oil & Gas Journal's oil reserve estimate for Canada includes 
5.392 billion barrels of conventional crude oil and condensate reserves and 173.2 billion barrels of oil sands reserves.   
4 Gulf Publishing Company, World Oil, Vol. 228, No.9 (September 2007), except United States.  Oil includes crude oil and condensate but excludes 
natural gas liquids.  Data for the United States are from the Energy Information Administration, U.S. Crude Oil, Natural Gas, 
and Natural Gas Liquids Reserves, 2006 Annual Report, DOE/EIA-0216(2007) (November 2007).  World Oil states that its  
Canadian oil reserves estimate "includes reserves that are recoverable with current technology and under present economic conditions."  It includes
20.665 billion barrels of oil sands and bitumen.  It excludes another 153 billion barrels of oil sands and bitumen claimed by Canadian authorities.    
5 Centre International d'Information sur le Gaz Naturel et tous Hydrocarbures Gazeux (CEDIGAZ), Natural Gas in the World, End of July 2008 
(Electronic Database), except United States. Data converted from cubic meters to cubic feet at 35.315 cubic feet per cubic meter.  United 
States data are from the Energy Information Administration, U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves,
