Drilling for Geology
Why do we
drill
boreholes?

Drilling for Geology
How many coal exploration and mining companies are
there in Australia?
How many data collection, database and modelling
packages are used by these companies?
How many geologists only work for 1 company in their
career?
What happens to the integrity of data acquired by different
geologists from different companies?

Drilling for Geology
What happens when companies merge and data has to
be integrated?
What standard is used by Government Departments
to store data made available on open file?
Wouldn’t it be better if there was one system, one set
of codes, that every company and Department used?

Drilling for Geology
What code
should I use
for the Pisces
Seam?
Why doesn’t
every company
use the same
codes?
Why didn’t the geo
know how to take
useful photos?
What data
entry sheet
should I use?
Is
Siltstone
SL or ST?
