Up until the mid-2000s, hydraulic fracturing was generally limited to conventional oil and gas wells in the Cooper Basin. This was limited to one, two, or sometimes zero ongoing fracturing operations.[citation needed] The vast majority of coal seam gas wells have not been hydraulically fractured as the wells presently being drilled are in coal seams that have good natural permeability.[citation needed] The NSW Government has banned BTEX chemicals as additives.[1] As of September 2016, Victoria has permanently banned hydraulic fracturing and all forms of unconventional gas extraction.[2]
