Crude Oil Analysis Database with 9,076 Samples

9,076 crude oil analyses from samples collected globally between 1920 and 1983, compiled by the U.S. Bureau of Mines. The database includes specific gravity, API gravity, pour point, viscosity, sulfur content, nitrogen content, and distillation cut properties. Data were digitized in the late 1970s and made publicly accessible through various systems.

Use Cases

• Analyze sulfur content and nitrogen content variations across different geographic sources to assess crude oil quality.
• Model pour point and viscosity relationships with API gravity for refining process optimization.
• Study the bulk properties of distillation cuts to characterize historical crude oil compositions.

Strengths

• Contains 9,076 distinct crude oil analyses, providing a substantial historical sample base.
• Data spans a 63-year collection period from 1920 to 1983, offering long-term historical context.
• Includes multiple standardized physical and chemical properties like specific gravity, pour point, and sulfur content.

Limitations

• Sample location information is generally inadequate, lacking specific well identifiers, lease names, or precise coordinates.
• Data is temporally stale, with the latest sample collection ending in 1983, not reflecting modern crude oil sources.
• The original data format (Foxpro .dbf, Microsoft Access) may require conversion for use with contemporary analysis tools.
