[MMBO, million barrels of oil. BCFG, billion cubic feet of gas. MMBNGL, million barrels of natural gas liquids. Fields containing less than 1 MMBO in oilfields or 6 BCFG in gas fields were not considered in the assessment. Fields were classified as oil or gas by the USGS. Fields without reported discoverydates were not included. NA means not applicable and is shown for volumes where only one field is present. Calculated values may not be equal to the
sums of the component values because numbers have been independently rounded.]
