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…

SKB - SICADA

MINING INDUSTRY

• > 1000 core drillings

• > 30 geologists done the logging = 30

different protocols!

• Most common rock type - ABOVE

GROUND

• Second most common rock type -

UNKNOWN

”-We have developed a very advanced and

complicated databasestructure…”

GLOBAL INTERACTION – EPOS

• OPEN data, standards, cooperation

• Huge data sets

• Easy access

• Positioning

• Who are the receivers – what tools do they

have

• Uncertainties

• Don´t look back
