The facts on Fracking! Over 18,600 gas wells in Australia already approved folks!

In Queensland in 2010/2011 some 18,600 gas wells were approved!

Coal seam gas mining involves drilling deep into the earth to extract methane held in a coal seam. In order to extract the gas, large volumes of salty water contained in the coal seam need to be brought to the surface.This water is the major waste product from coal seam gas mining. Methods used to extract the gas include hydraulic fracturing or lateral drilling. Both of these methods represent risks to groundwater.

As well as the underground impacts described above, coal seam gas mining has severe surface impacts. It requires large numbers of wells to extract the volumes of gas that are sought – in Queensland in 2010/2011 some 18,600 gas wells were approved. Along with gas wells come roads, pipelines, tracks, compressor stations and water storage ponds – which altogether results in an industry which spreads out across the landscape and carves up rural landscapes into giant industrial zones.


From an article on the ‘Lock the gate alliance’ website

Interestingly when I read this article, a lot of the links have been deleted, documents removed and pages missing – something to hide maybe??

Hydraulic fracturing, more commonly known as fracking or fraccing, is a technique used to stimulate and accelerate the flow of gas to a well or bore. The process involves high-pressure injection of sand, water and chemicals into the gas-bearing rock. The injection causes fractures in the rock allowing the gas to flow to the surface of the well.

The coal seam gas industry used to provide a list of chemicals it says are used in coal seam gas fracking operations in Australia – I’ve noticed they’ve now deleted that page and replaced it with this This link is very interesting in that it sites report in the USA on Fracking – their findings contradict the actual report in the link below called study .

The National Toxics Network  has raised various concerns about the environmental and health risks associated with the chemicals associated with hydraulic fracturing and has said that these chemicals are not adequately assessed or monitored, and yet we’ve got 1,000’s of wells already approved?? Hello?

BTEX (an acronym that stands for benzene, toluene, ethylbenzene, and xylene) is one group of chemicals associated with hydraulic fracturing. BTEX can be naturally occurring (interesting, this page has gone too) and benzene is a known carcinogen (cancer causing).The National Toxics Network says that the fracking process itself can release BTEX from the natural-gas reservoirs, which may allow them to disperse into the groundwater aquifers or to volatilise into air. Doctors for the Environment point out that a range of other hazardous chemicals are reported to be used in Australian fracking operations including 2-butoxyethanol and ethylene glycol.

Research compiled by Doctors for the Environment found that 2-butoxyethanol is easily absorbed and rapidly distributed in the human body and is particularly toxic to red blood cells, carrying the risk of haemolysis, and damage to spleen, liver and bone marrow. Ethylene glycol (interesting, this has been removed too)  is used to make anti-freeze and when ethylene glycol breaks down in the body it can affect kidney function as well as the nervous system, lungs and heart.

report (oh, this link has vanished too!!)  by the Committee for Economic Development of Australia said: In addition to concerns over contamination of aquifers from the chemicals added to fracking fluid, issues have also been raised about contamination of water supplies from fugitive gas after fracking, and seismic activity and tremors associated with the drilling and fracking process.

A process known as ‘flowback’ is used to recover fracking fluids previously pumped underground. The National Toxics Network says that “as well as the original fluid used for fracturing, flowback may also contain other fluids, chemicals and minerals that were present in the fractured formation such as heavy metals and hydrocarbons”. Flowback does not recover all of the fracking fluid. A report prepared in 2010 for the coal seam gas industry said (surprisingly this link is still there) “It is conservatively assumed that 40% of the hydraulic fracturing fluid volume would remain in the formation and this would correspond to 7400kg of chemicals per injection well…”

Other significant concerns associated with hydraulic fracturing including the potential to contaminate water sources and cause earthquakes. A study conducted in the United States in 2011 documented “systematic evidence for methane contamination of drinking water associated with shale-gas extraction”. In the United Kingdom in 2011 the British Geological Survey confirmed seismic events were a direct result of drilling and fracking activities by Cuadrilla Resources.

Fracking has been used during coal seam gas operations in both Queensland and NSW and there remain widespread calls for a moratorium or ban on its use. A moratorium on the use of hydraulic fracturing in NSW was recently lifted by the state government. More reading below!
