Sandstone Uranium Potential Analysis from Alberta Well Logs

Gamma-ray log data from over 22,000 oil and gas wells in Alberta was analyzed to evaluate sandstone-hosted uranium potential. The Alberta Geological Survey processed more than 48,000 logs, identifying 11,476 readings above 300 API within the upper 500 meters. This dataset supports Open File Report 2009-0012 and was last updated in March 2026.

Use Cases

• Identify wells with high gamma-ray readings (>300 API) for uranium prospecting.
• Correlate gamma, density, and resistivity log features to determine rock types.
• Map spatial distribution of anomalous gamma-ray readings across 6,176 wells.
• Validate uranium potential algorithms using a subset of 1,318 verified wells.

Strengths

• Analysis covers more than 48,000 gamma-ray logs from over 22,000 wells.
• Includes 11,476 specific high-gamma readings (>300 API) identified for study.
• Rock type verification performed on a subset of 1,318 wells using multiple log types.

Limitations

• Specific column names and full data schema are not provided.
• Dataset size, row count, and complete temporal range are unknown.
• Analysis is focused on the upper 500 meters, excluding deeper geological formations.
