FOR every “fracked” coal-seam gas well, between 10,000 and 35,000 litres of chemicals are injected into the ground, with up to 40 per cent remaining there.
The CSG industry has talked down the quantity of chemicals used in the process, repeatedly stating the chemicals represent roughly 1 per cent of fracking solution.
The Senate committee into CSG, which delivered an interim report this week, has examined the bulk of chemicals used in the hydraulic fracturing or “fracking” process. It states that because of the very large volumes of solution involved, “even 1 per cent is still a significant volume”.

Queensland’s environment minister will investigate claims her department allowed coal seam gas (CSG) water to be dumped into a river in breach of national standards.
An ABC Radio investigation found treated CSG water, containing chemicals and traces of heavy metals, was dumped into the Condamine River in southeast Queensland.

Crucially, we have rushed to develop coal seam gas reserves as a cleaner alternative to coal, assuming it will help reduce greenhouse gas emissions and tackle climate change. But will coal seam gas reduce emissions? By how much? We don’t actually know.

COAL seam gas drilling at a flashpoint site on the edge of the Liverpool Plains has been halted after the state’s biggest coal seam gas operator, Santos, backed down, ending a three-week blockade by residents.
The halt came as the O’Farrell government was forced into damage control over coal seam gas exploration after the Minister for Western NSW, Kevin Humphries, appeared to foreshadow a suspension of pilot production across the state.

Protecting the water wealth of the Great Artesian Basin is the latest challenge for the coal seam gas industry, writes Ben Cubby.
The basin has existed in its current form for millions of years, but one of the biggest tests to its existence will come in the next decade. Beneath the layers of water lie some of the world’s most extensive coal seams. Just as the sandstone aquifers contain water, so the coal seams contain methane.

The root of the problem, he says, is that politicians pay little attention to the long-term effects of decisions, especially the impact of mining on water resources.
“One thing people must have is food and water, but we are destroying that for one-off payments from mining,” he says.
“No one has a clue of the geology of aquifers. Once fractured, there’s no possibility for them to be fixed. You can’t mine without fracturing the aquifer.”
“The single most important thing you can have is water,” Mr Ball said.

Senior energy analyst Gundi Royle has broken ranks with her colleagues, attacking industry and regulators for failing to conduct independent regional modelling of the groundwater impacts of up to $80 billion in planned coal seam gas (CSG) development.
She said that State governments were so enamoured with projected revenue “they cannot regulate efficiently. They have failed from the outset. They are trying to run behind the ambulance but they will not be able to catch it”.

With opponents to coal seam gas fighting the industry on many fronts the news that gas producers pay nothing for five years has been met with disbelief.
Those opposed to the industry have been questioning its impact on the environment in particular ground water – but now they want to know how a multinational run industry can receive such a significant financial boost from the state government.

The only company in Britain using hydraulic fracturing to release natural gas from shale rock says the controversial technique probably did trigger earth tremors in April and May. Fracturing operations were suspended on May 27 following the detection of a tremor centred just outside Blackpool.
