1995 USGS Oil and Gas Production Grid for Los Angeles Basin

Quarter-mile cell maps illustrate oil and gas exploration maturity and production types across the Los Angeles Basin. The U.S. Geological Survey created this assessment in 1994 using proprietary well data current to December 1990. It covers seven conventional oil and gas plays within the province.

Use Cases

• Classify quarter-mile cells as oil-producing, gas-producing, both, or dry based on well data.
• Analyze the distribution of production types across seven defined conventional plays like the Newport-Inglewood Deformation Zone.
• Map exploration maturity and historical activity density within the Santa Monica Fault System play.
• Compare production characteristics between different geological features such as fault zones and shelves.

Strengths

• Data is structured on a standardized quarter-mile grid for spatial analysis.
• Covers seven distinct conventional oil and gas plays within a defined province.

Limitations

• Underlying well data is from 1990, making the resource assessment over 30 years old.
• Specific row counts, column details, and sample sizes are not provided.
