In the spring, lightning would sometimes ignite the coal deposits underground, firing the clay above them into brick-red porcelainite.
Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes.
The extracted carbon dioxide can then be compressed, stored in liquid form and deposited underground using carbon capture and storage technologies.
It deploys a secret new form of plastic which the team says attracts CO2 in a way that allows the gas to be captured, compressed and then safely deposited underground.
Ian D. Gates, chairman of the department of petroleum engineering at the University of Calgary, said that it was unlikely that the oil sands deposits underground would be affected, but that the bitumen in oil sands already at the surface, exposed by mining or erosion, might burn if a sufficiently hot wildfire were to reach them.
Huge protests were staged outside the site of the drilling over fears the exploratory work could lead to fracking, which is the process of forcing water, chemicals and sand at high pressure into shale rock deposits underground.
After transport to a storage site, CO2 is then deposited underground in adequate geological formations in order to not enter the atmosphere as a contribution to climate change mitigation.
