British Geological Survey archives contain scanned images of over 1 million records for onshore Great Britain boreholes, trial pits, shafts, and wells. Scanning began in 2002 and is ongoing, with approximately 50,000 new records added annually. The collection includes records ranging from simple lithological logs to hydrocarbon completion reports.
Use Cases
- Extract lithological log text from scanned borehole records for geological unit classification.
- Analyze the temporal distribution of scanned hydrocarbon completion reports to map exploration activity.
- Digitize and georeference borehole and well locations from scanned records for spatial analysis.
- Train an image classification model to categorize scanned records by type, such as trial pit logs or shaft reports.
Strengths
- Over 1 million scanned records provide a substantial historical archive.
- Approximately 50,000 new records are added per year, ensuring ongoing growth.
- Collection includes diverse record types, from single-page logs to detailed completion reports.
Limitations
- Data is presented as scanned images, requiring OCR or manual transcription for text-based analysis.
- Specific metadata columns, file formats, and sample data are not provided in the input.
- The scanning project started in 2002, so the digital archive's coverage of older physical records may be incomplete.
