1995 National Oil and Gas Assessment Plays for Ventura Basin Province

Geologic boundary definitions for conventional oil and gas plays used in the 1995 U.S. National Assessment. The dataset includes five plays within Province 13 (Ventura Basin), defined by geologists from the CEOS_EXTRA organization between 1993 and 1994. Boundaries represent the limits of geologic elements like reservoir rock and structures.

Use Cases

• Mapping the spatial extent of the 'Paleogene - Onshore' (1301) and 'Neogene - Onshore' (1302) plays for basin analysis.
• Analyzing the distribution of play types, such as 'Cretaceous' (1304) versus offshore plays, for regional geologic studies.
• Joining play boundaries with other assessment data using the play 'Number' and 'Name' fields for integrated resource evaluation.

Strengths

• Defined by expert geologists responsible for the province during the national assessment.
• Boundaries are based on specific geologic elements like reservoir rock limits and structures.

Limitations

• Temporal coverage is static, representing a single assessment from 1995 with boundaries defined in 1993-1994.
• Dataset size, row count, and specific column details are unknown.
• Limited to five listed plays within one province, may not represent full basin complexity.
