    The Energy Information Administration reports that discoveries in western states and the Gulf of Mexico have produced an increase in U.S. reserves. Crude reserves totaled 22.0 billion bbl at year-end 2000, up 1.3% from the previous year. Proven dry natural gas grew 6% to 177.4 Tcf, representing the largest increase since the agency began tracking annual reserves 24 years ago. Due to diminishing frontier (drilling) areas, "such unusually large (gas) increases should not be expected very often," said EIA. The gas reserves came from Texas and New Mexico, along with states that have large increases in coalbed methane reserves.
