Five conventional oil and gas plays define the fundamental assessment units for the 1995 U.S. National Oil and Gas Assessment within province 18. The dataset provides geologic boundaries for plays like the Hornbrook Basin-Modoc Plateau and Eastern Oregon Neogene Basins. Boundaries were defined by geologists for the U.S. Geological Survey between 1993 and 1994.
Use Cases
- Map the geographic extent of play 1801 (Hornbrook Basin-Modoc Plateau) for regional resource analysis.
- Analyze the spatial relationship between plays defined by different source rock ages (e.g., Permian-Triassic vs. Neogene).
- Use play boundaries and names (e.g., 'Cretaceous Source Rocks, Northwestern Nevada') as input features for basin-scale resource prediction models.
Strengths
- Provides the fundamental geologic assessment unit (play) for a national U.S. survey.
- Contains boundaries for five distinct plays within a defined province.
Limitations
- Data reflects the geologic understanding and assessment methodology from 1993-1994, which may be outdated.
- No quantitative resource estimates, well data, or columnar attributes are included in this boundary dataset.
Provenance
- Source
- U.S. National Oil and Gas Assessment, likely authored by the U.S. Geological Survey.
- Collection Method
- Geologic boundaries defined by the responsible geologist for each province based on limits of geologic elements.
- Time Range
- Assessment period circa 1995, with boundaries defined 1993-1994.
- Freshness
- null
- Geography
- Western Great Basin Province (Province 18), covering parts of Nevada, Oregon, and California.
