Geologic boundaries for six conventional oil and gas plays defined for the 1995 U.S. National Oil and Gas Assessment within the Uinta-Piceance Basin Province. The assessment was conducted by geologists from the CEOS_EXTRA organization, with play boundaries mapped between 1993 and 1994. This dataset serves as the fundamental geologic unit for that national resource evaluation.
Use Cases
- Spatial analysis of play boundaries like 'Piceance Tertiary Conventional' or 'Basin Margin Subthrusts' to correlate with seismic survey data.
- Regional resource estimation by aggregating potential across defined plays such as 'Upper Cretaceous Conventional' and 'Permian-Pennsylvanian Sandstones and Carbonates'.
- Historical comparison of 1995 assessment units like play '2004' (Cretaceous Dakota to Jurassic) with modern geologic interpretations.
- Mapping the geographic extent of source rock and reservoir limits as defined for plays including 'Uinta Tertiary Oil and Gas'.
Strengths
- Defined boundaries for six distinct conventional plays provide a structured assessment framework.
- Play definitions incorporate specific geologic elements: source rock, migration pathways, trapping mechanism, and hydrocarbon type.
Limitations
- Data reflects a 1995 assessment and may not incorporate discoveries or geologic understanding from the last three decades.
- The dataset contains only play boundaries and names, lacking quantitative resource metrics or well data.
- Spatial coverage is limited to a single province (Uinta-Piceance Basin).
