1995 USGS Oil and Gas Production Cells for Western Great Basin

USGS cell maps illustrate exploration maturity and production types for oil and gas plays within the Western Great Basin province. Each quarter-mile cell is coded based on whether contained wells are predominantly oil-producing, gas-producing, both, or dry. The dataset was created in 1994 using well data current as of December 1990.

Use Cases

• Analyze spatial distribution of oil-producing versus gas-producing cells across the Hornbrook Basin-Modoc Plateau play.
• Map exploration maturity by play type (e.g., conventional) and play number (e.g., 1801-1805) within province 18.
• Identify clusters of dry cells versus productive cells to infer historical drilling outcomes at a quarter-mile resolution.

Strengths

• Data covers five distinct conventional oil and gas plays within a defined province.
• Cell-level coding provides a standardized graphic representation of proprietary well data.

Limitations

• Well data is current only to December 1990, making it a historical snapshot.
• No proprietary well records are included, limiting detailed well-level analysis.
• Specific row counts, column details, and sample sizes are unavailable.
