1995 USGS Oil and Gas Assessment Cells for San Joaquin Basin

USGS cell maps illustrate oil and gas exploration maturity, production type, and distribution for the San Joaquin Basin Province. The dataset comprises quarter-mile square cells coded for predominant well production status. Data originates from the 1995 U.S. National Oil and Gas Assessment, with source well information current as of December 1990.

Use Cases

• Analyze spatial distribution of oil-producing versus gas-producing cells across the San Joaquin Basin.
• Map exploration maturity by play number and play type (e.g., conventional) for regional assessment.
• Identify geographic clusters of dry wells versus productive wells using quarter-mile cell coding.
• Correlate production types with specific geological plays like the 'West Side Fold Belt' or 'Tejon Platform'.

Strengths

• Data covers 11 distinct oil and gas plays within a major U.S. basin.
• Spatial resolution is standardized at the quarter-mile cell level.

Limitations

• Source well data is over 30 years old, current only to December 1990.
• Specific row count, column details, and sample size are unknown.
