SODIR Data Extractor Skill

Extract and process Norwegian Petroleum Directorate (SODIR) field and production data

When to Use This Skill

Use this skill when you need to:

• Extract Norwegian continental shelf field data
• Query SODIR production statistics
• Compare Norwegian fields with GOM fields
• Build cross-basin analysis datasets
• Access historical NCS field performance

CLI Usage

# Extract field list
python -m worldenergydata.sodir \
    --action list-fields \
    --status PRODUCING \
    --output data/sodir/fields.csv

# Get production data
python -m worldenergydata.sodir \
    --action production \
    --field "JOHAN SVERDRUP" \
    --start-year 2019 \
    --output data/sodir/johan_sverdrup.csv

Best Practices

1. Cache SODIR data locally to reduce API calls
2. Use field names exactly as they appear in SODIR
3. Convert units (Sm3 to bbl) for comparison with BSEE data
4. Handle missing data gracefully for early production periods
