Petroleum systems and geologic assessment of oil and gas in the Uinta-Piceance Province, Utah and Colorado

Data Series 69-B



The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geology-based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States, focusing on the distribution, quantity, and availability of oil and natural gas resources. The USGS has recently completed an assessment of the undiscovered oil and gas potential of the Uinta-Piceance Province of northeastern Utah and northwestern Colorado (USGS Province 5020). The Uinta- Piceance Province is a priority province for the National Assessment because of its potential for significant natural gas resources.


The assessment of this province is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy, petrophysical properties), and hydrocarbon traps (trap formation and timing). In the Uinta-Piceance Province, the USGS used this geologic framework to define five total petroleum systems and 20 assessment units within the total petroleum systems, and quantitatively estimated the undiscovered oil and gas resources within each assessment unit.


Many more details about the project and about individual chapters of this report are readily available in the very readable Chapter 2 of this volume, 'The Uinta-Piceance Province-Introduction to a geologic assessment of undiscovered oil and gas resources.'
