In 1987, the US Geological Survey and Minerals Management Service completed the assessment of the undiscovered conventional resources of crude oil and natural gas in the US. The assessed resources were defined as (1) those considered recoverable under current technology and (2) those that could be recovered economically under specified price-cost relationships. Not included in the study were resources from tar deposits, heavy oil deposits, oil shales, gas in low-permeability tight reservoirs, coal-bed methane, gas in geopressured shales and brines, and gas in natural gas hydrates. The assessments were based upon the analysis of oil and gas plays and prospects supported by studies and analysis of the petroleum geology, exploration history, finding rates, and field-size distributions. Probability procedures were used in their derivation. The estimates of undiscovered recoverable conventional oil resources for the US range from 33 to 70 billion bbl, with a mean estimated of 49 billion bbl. The estimates of undiscovered gas range from 307 to 507 trillion ft/sup 3/, with a mean of 399 trillion ft/sup 3/. The undiscovered economically recoverable oil and gas resources for the US are estimated to range from 21 to 54 billion bbl of oil and 208 to 326 trillion ft/sup 3/ of gas. The mean value for oil is 35 billion bbl and for gas is 263 trillion ft/sup 3/.
