operating conditions. 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 derfinitions, 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."  3 PennWell Corporation, Oil & Gas Journal, Vol. 104.47 (December 18, 2006).  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,  2005 Annual Report, DOE/EIA-0216(2005) (November 2006).  Oil & Gas Journal's oil reserve estimate for Canada includes  5.2 billion barrels of conventional crude oil and condensate reserves and 174.0 billion barrels of oil sands reserves.    4 Gulf Publishing Company, World Oil, Vol. 227, No.9 (September 2006), 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, 2005 Annual Report, DOE/EIA-0216(2005) (November 2006).  World Oil states that its   Canadian oil reserves estimate "Includes reserves that are recoverable with current technology and under present economic conditions.  Includes 7.58 billion bbl of oil sands and bitumen."     5 Centre International d'Information sur le Gaz Naturel et tous Hydrocarbures Gazeux (CEDIGAZ), Natural Gas in the World, End of July 2006  (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,  2005 Annual Report, DOE/EIA-0216(2005) (November 2006). 6 Includes one-half of the reserves in the Neutral Zone, if separately reported.
