California Oil and Gas Wells by Type and Status

WellSTAR maps oil and gas wells across California, tracking them by well type and operational status. The dataset is maintained by the state's Geologic Energy Management Division (CalGEM) and was last updated in March 2026.

Use Cases

• Map well locations by well type and well status for spatial analysis of energy infrastructure.
• Analyze the distribution of well status categories to monitor active, idle, and abandoned sites.
• Integrate geospatial data via formats like GEOJSON or KML for environmental impact studies.

Strengths

• Data is sourced from the official California state regulatory agency, CalGEM, ensuring authoritative records.
• Offers multiple access formats including CSV, GEOJSON, and KML for flexible analysis.
• Includes a recent update timestamp from March 2026, indicating ongoing maintenance.

Limitations

• The sample data and specific row/column counts are unavailable, making initial assessment difficult.
• Update frequency is listed as 'As Needed,' which may result in irregular or infrequent refreshes.
• Lacks detailed column definitions, limiting understanding of specific attributes beyond type and status.
