Notes: · Data are at end of year. · See "Proved Reserves, Crude Oil," "Proved Reserves, Lease Condensate," "Proved Reserves, Natural Gas," and "Proved Reserves, Natural Gas Liquids" in Glossary.			Sources: Cumulative Production: Calculated from Energy Information Administration (EIA), Petroleum Supply Annual, annual reports and Natural Gas Annual, annual reports. Proved Reserves: · 1977-2005—EIA, U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves, annual reports. · 2006—EIA, U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves 2006 Annual Report (December 2007), Tables 6, 8, and 15. Proved Ultimate Recovery: Calculated as the sum of cumulative production and proved reserves.
