National Assessment of Oil and Gas Fact Sheet

Assessment of Undiscovered Oil and Gas Resources of the Southwestern Wyoming Province, 2002

Table 1. Southwestern Wyoming Province assessment results.
Table 1. Southwestern Wyoming Province assessment results. [MMBO, million barrels of oil; BCFG, billion cubic feet of gas; MMBNGL, million barrels of natural gas liquids. Results shown are fully risked estimates. For fields, all liquids are included under the NGL (natural gas liquids) category. F95 denotes a 95-percent chance of at least the amount tabulated. Other fractiles defined similarly. Fractiles are additive only under the assumption of perfect positive correlation. CBG, coal-bed gas. Shading indicates not applicable (N / A)]
