National Assessment of Oil and Gas Fact Sheet

Assessment of Undiscovered Oil and Gas Resources of the Eastern Great Basin Province, 2005

thumbnail image of figure 1. The Eastern Great Basin Province

The U.S. Geological Survey (USGS) recently completed an assessment of the undiscovered oil and gas potential of the Eastern Great Basin Province of eastern Nevada, western Utah, southeastern Idaho, and northwestern Arizona. The province includes Neogene basins, Neogene ranges and structures, the central Nevada thrust belt, and the Sevier thrust belt. The assessment was based on the primary geologic elements that constitute a total petroleum system (TPS): petroleum source rocks (source rock maturation, petroleum generation, and migration), reservoir rocks (based on sequence stratigraphy and petrophysical properties), and petroleum traps (formation and timing). Using this geologic framework, the USGS defined the Paleozoic-Tertiary Composite TPS and three assessment units (AU) within the TPS, and quantitatively estimated the undiscovered oil and gas resources within the three AUs.
