Uinta-Piceance Basin Continuous Oil and Gas Plays from 1995 National Assessment

CEOS_EXTRA provides a map of geologic boundaries for continuous-type oil and gas plays defined for the 1995 U.S. National Oil and Gas Assessment. The dataset lists 15 specific plays within the Uinta-Piceance Basin province, identified by number and name. Play boundaries were defined by geologists between 1993 and 1994.

Use Cases

• Spatial analysis of play boundaries like 'Tight Gas Piceance Mesaverde Williams Fork' to correlate with subsurface geology.
• Categorizing hydrocarbon resource types using the play name field, such as 'Cretaceous Self-Sourced Fractured Shales Oil'.
• Historical comparison of assessment units by linking play numbers (e.g., 2007, 2050) to later resource estimates.
• Mapping the distribution of play types like 'Basin Flank Uinta Mesaverde' against regional tectonic features.

Strengths

• Defines 15 distinct continuous oil and gas plays within a major U.S. basin province.
• Play boundaries were defined by geologists responsible for the province, providing expert delineation.
• Represents the fundamental assessment unit for the authoritative 1995 U.S. National Oil and Gas Assessment.

Limitations

• Assessment data is from 1995, making it temporally stale for current resource estimates.
• No quantitative resource data (e.g., volumes, probabilities) is provided, only play definitions and names.
• Geographic coverage is limited to a single province (Uinta-Piceance Basin).

Provenance

Source

CEOS_EXTRA, likely originating from the U.S. Geological Survey or related assessment bodies.

Collection Method

Geologic mapping and expert interpretation by province geologists to define play boundaries.

Time Range

Assessment reflects knowledge and boundaries defined circa 1993-1995.

Freshness

Data reflects the 1995 assessment, with play boundaries defined in 1993-1994. Last updated date is 1996-12-31.
