South-East fracking ban set to be legislated by South Australian Government

A decade-long ban on hydraulic fracturing — better known as fracking — in South Australia's Limestone Coast region looks set to be enshrined in law.

The State Government has backflipped on its opposition to legislating a moratorium, and will support a bill put forward by Mt Gambier independent MP Troy Bell, a former Liberal.

"It's not that the South-East is against mining or gas extraction, it's this technology, in that location over limestone where there's aquifers that the entire region relies on."

Northern Territory lifts fracking ban, opening up 700,000 sq km to gas exploration

The Northern Territory government has lifted a ban on hydraulic fracturing of onshore gas that will open up more than half of the territory’s land mass to the controversial practice.
 The Northern Territory has lifted a ban on fracking ban
and opened 51% of the territory to gas exploration. 
The first exploration fracking by petroleum companies is expected to occur early next year after the implementation of a regulatory regime and new laws, which the government insists will be strict.

The issue has sharply divided territorians, many of whom believe fracking threatens water supplies, but the chief minister, Michael Gunner, said on Tuesday the industry would create jobs.

Fracking ban in the Northern Territory should stay, group of leading climate scientists says

Thirty-one of Australia's leading climate scientists and doctors have written an open letter to the Northern Territory Government calling on it to not permit the opening up of new gas fields through hydraulic fracturing.
The scientists say the estimated emissions rise
from developing one gas field is unacceptable.
The letter, coordinated by the Australia Institute think tank, also called on the Territory Government's fracking inquiry panel to recommend that new shale gas fields are too risky because of the consequences of potentially increasing greenhouse gas emissions.

The Territory Government will make a decision on whether to allow fracking of major shale gas reserves to resume after its inquiry delivers a final report next month.

"The NT is in the region likely to experience the most severe impacts of global warming, for example it is highly susceptible to temperature increases," wrote the scientists, including the CSIRO's Climate Change Hub leader Professor David Karoly.

Fracking – the reality, the risks and what the future holds

Hydraulic fracturing, or fracking as it is better known, is a method of extracting oil and gas trapped in shale and other rock formations.

The US expects to produce 7.5m barrels of shale oil per day
 by 2040, but in the UK fracking faces strong resistance. 
The modern version involves pumping large amounts of water down a well at high pressure, along with sand and chemicals that make up a tiny fraction of the volume. Together, this “stimulation fluid” fractures the rock and releases the gas or oil, which flows to the surface. The hole drilled for a well is about the size of a manhole cover.

As the UK industry body explains, the sand is there to keep fractures in the rock open. The chemicals are included for several purposes, such as lubrication and keeping bacteria out.

The other big technological development that has made fracking economical is horizontal drilling. This means that several horizontal boreholes can be drilled off one well, like tributaries off a river, maximising the amount of oil and gas that can be recovered. This spring, either Third Energy in North Yorkshire or Cuadrilla in Lancashire will become the first company to frack in the UK since 2011.

Remote Northern Territory businesses weigh up potential impacts of fracking

Small business owners in a remote part of the Northern Territory are weighing up the potential effects of hydraulic fracturing on their livelihood and the environment.

Jack Harries says his business could benefit
from the development of a shale gas industry in the NT.
A moratorium on the controversial underground gas extraction technique is currently in place in the NT, with a decision to be made on its lifting awaiting the outcome of an independent scientific inquiry into hydraulic fracturing, due late this year.

While the inquiry sits, gas company Origin Energy has its sights on the Beetaloo Basin, about 600 kilometres south-east of Darwin, where it believes a huge amount of gas lies underground.

For the owners of small businesses in the region, the prospect of the development of a shale gas industry could provide a significant boost to their trade, or unknown environmental consequences.

New energy rush is simply' snake oil'


Energy and our profligate use of it is the essence of the difficulties that have compounded to become climate change.

Richard heinbeg's new
 book, "Snake Oil".
Suddenly, those who capitalize on that want, have uncovered new technologies that have allowed them to drill horizontally into earth rock structures and then unleash gas and oil hidden there for millennia using hydraulic fracturing.

These developments have resulted in a new “rush” as those who see the potential scurry to raise the needed cash assemble the needed equipment and extract this newfound energy.

Promises and predictions surround this new “rush”, but the hollowness of those claims is explored by Richard Heinberg in his new book, “Snake Oil: How fracking’s false promise of plenty imperils our future”.

Writing at the beginning of his new book, Heinberg writes:

“Finally, and probably most importantly, this book is directed toward anyone who cares about the fate of our planet. The only realistic to avert catastrophic climate change is to dramatically and quickly reduce our consumption of fossil fuels. That project will pose economic and technical challenges. But politics may present the biggest obstacle of all.”

Heinberg slices through the hype and glib statements of those who believe in a promote fracking, illustrating, through undeniable facts, that the promises are really simply too good to believe.

He explains how the promised increases are little more than that and give us nothing more than temporarily increased production and ultimately do nought to ease our energy limitations.

Delving into the complexities of Energy Returned on Energy Investment (EROEI) and Heinberg ask his readers to consider the two equally true statements:


Hydrocarbons are so abundant that, if we burn a substantial portion of them, we risk a climate catastrophe beyond imagining.
 

There aren’t enough economically accessible, high-quality hydrocarbons to maintain economic growth for much longer.
 

Richard Heinberg.
He writes: “Here is a public relations nightmare: how to convey these seemingly contradictory messages to people without confusing he bejesus out of them. How can concepts like ‘energy return on energy invested’ to an audience that barely understands what energy is?  How can millions of half-somnolent television addicts be guided in understanding ‘fugitive methane emissions,’ ‘energy density’ and a dozen other essential terms and concepts?”

Heiberg says the answer lies in what he describes as “literally humanity’s project of the century.”

“It is an enormous challenge, but it is not optional.”

“We either break the addiction, or we suffer the consequences – which would impact not just on ourselves, but future generations as well,” he writes.

We face a choice, he says, jobs and economic growth on one hand, or climate protection on the other.

Heinberg’s book - “Snake Oil: How fracking’s false promise of plenty imperils our future” is worth reading.
