"The unique centrifuge takes clay samples from the walls of underground aquifers and subjects them to extreme pressure."
A new machine will be used to solve one of the more contentious mysteries of coal seam gas extraction—how it will affect underground water supplies.
The unique centrifuge, to be used by researchers at the University of NSW, takes clay samples from the walls of underground aquifers and subjects them to extreme pressure.
Samples can be exposed to pressures up to 300 times the level of standard gravity, and fine-tuned to trace local conditions at a particular mine site. . .View full article
