World Undiscovered Assessment Results Summary | |||||||||||||
[MMBO, million barrels of oil. BCFG, billion cubic feet of gas. MMBNGL, million barrels of natural gas liquids. Prob., probability (including both geologic and accessibility probabilities) of at least one field equal to or greater than the minimum assessed field size. Results shown are fully risked estimates. For gas fields, all liquids are included under the NGL (natural gas liquids) category. F95 represents a 95 percent chance of at least the amount tabulated. Other fractiles are defined similarly. Fractiles are additive under the assumption of perfect positive correlation. For the total of non-U.S. undiscovered petroleum, the resources in oil fields and in gas fields were aggregated by a separate Monte Carlo procedure from that of total resources; thus these lines do not add perfectly.
