Source: U.S. Department of Energy, Energy Information Administration, Annual Energy Review 1991, table 42, p. 95, DOE/EIA-0384(91), (Washington, DC: DOE, EIA, 1992) Notes: Proved reserves of crude oil, natural gas, and natural gas liquids combined increased every year from 1949 to 1968 as new reserves were discovered. Except for the addition of Alaska's North Slope reserves in 1970, proved reserves have trended downward since 1968. Reserves of natural gas alone increased in 1990, largely due to growth in reserves in coalbed methane fields. About one-half of the demonstrated coal reserve base is estimated to be recoverable. Uranium resources include reasonably assured reserves in the forward production cost category of $30.00 per pound or less. Related Tables: 15-26, 52, 88-89, 97. |
