MODELS
• What is a model?
• Geometry (Volume/Surface/Zone)
• Properties
• Quality assurance (QA)
• Criteria?
• Who?
• Uncertainties
• (RMS, Std dev, +/-, probability…)
• Coordinate and elevation
system
• Type of database
• Separate from data?

ROCK LABORATORIES TODAY
– DATABASE STATUS
• NGL conference 2016
• All European rock laboratories, 2 things in
common:
1. ”- A highly valuable database with
somanymillion observations.”
2. ”- Only one person who really knows how to
handle it and what is in it”

• ”… - After a number of failed trialsI ended up travelling to Östhammar to sit down withMarie…”
• Conclusion – maybe start on something new… don´t look back…
