1995 USGS Oil and Gas Assessment Cells for Idaho Snake River Province

Quarter-mile cell maps illustrate exploration maturity and production type for oil and gas plays within the Idaho - Snake River Downwarp Province. The USGS created these maps in 1994 using well data current as of December 1990. This dataset is part of the 1995 U.S. National Oil and Gas Assessment.

Use Cases

• Classify quarter-mile cells as predominantly oil-producing, gas-producing, both, or dry based on contained well data.
• Analyze the distribution of production types across the Idaho - Snake River Downwarp Province using geospatial cell coding.
• Compare exploration maturity and production characteristics between conventional plays like Miocene Lacustrine and Pliocene Lacustrine.
• Map the geographic extent of defined plays (e.g., 1701, 1702, 1703, 1704) using their quarter-mile cell representations.

Strengths

• Data is structured at a consistent quarter-mile cell resolution for spatial analysis.
• Derived from a comprehensive commercial well database (Petroleum Information WHCS) covering most U.S. wells.
• Explicitly lists four conventional oil and gas plays within the province by number, type, and name.

Limitations

• Well data is temporally stale, current only as of December 1990.
• No proprietary well data is included, limiting detailed well-level analysis.
• Specific row counts, column details, and total geographic area covered are unknown.

Provenance

Source

U.S. Geological Survey (USGS), derived from the Petroleum Information Well History Control System (WHCS).

Collection Method

Cells were created as a graphic solution to display proprietary data without including it, coded based on predominant well production type within each quarter-mile square.

Time Range

Assessment data current as of 1990-12-01; maps created in 1994 for the 1995 national assessment.

Freshness

1990-12-01
