The recent controversy surrounding oil and gas exploration in the Sackville area has, rather suddenly and unexpectedly, catapulted the issue of hydraulic fracturing of natural gas to the forefront of New Brunswick politics.
Hydraulic fracturing or "hydro-fracking" is a relatively novel form of gas extraction that involves the injection of a mixture of water, sand and chemicals under high pressure to create cracks or fissures in shale rock formations deep underground.
Such fracturing facilitates the release of previously trapped methane gas deposits that are subsequently collected and extracted through the original drill bore.
