A BRIGHT orange vibrating truck will help shake up a study at the Nirranda South carbon storage research project .
The truck (pictured) from the Leibniz Institute for Applied Geophysics in Hannover, Germany will travel along minor roads in the Nirranda area in November, conducting a shear wave seismic study.
The truck has a large vibrating pad that lowers to the ground and vibrates.
The vibrations bounce off the rock layers below and are picked up by sensors laid out on the side of the road.
The vibrations give the operators a highly- accurate picture of the rock layers underground, as far down as half a kilometre.
Shear wave surveys are sensitive to porous rock, the kind of rock in which carbon dioxide can be safely stored.
Seismic surveys are one of several methods used to confirm that carbon dioxide is safely stored deep underground.
The carbon storage project at Nirranda South aims to demonstrate that carbon capture and storage is a technically and environmentally-safe way to make deep cuts into Australia’s greenhouse gas emissions and ease the effects of climate change.
More than 65,000 tonnes of carbon dioxide have been injected and stored in a depleted gas reservoir deep underground and further injections into different formations are planned.
The results of the shear wave seismic study will inform the next major experiment at the site, which will test the accuracy of permanent sensors in picking up a small injection of carbon dioxide.
The vibrating truck will travel at less than ten kilometres per hour and there will be no disruption to drivers or stock during the study. Normal traffic will take priority and all roads will remain open.
More information about the study will be available at a public meeting on Wednesday, September 18, at the project visitors’ centre on Brumby’s Lane, near the Nirranda CFA shed.
The project will also hold an open day on Sunday, October 13, when tours of the facility will be available and scientists involved in the research will talk about their work.
