Anti-fracking Meeting in Heathfield

Sorry to be telling you about this after the event, it was very badly advertised and I only found out about it at the last minute. Last week I went to a presentation by Ian Crane, the anti-shale gas campaigner. Ian is an interesting man, he worked in the drilling industry for 20 years, becoming a vice-president of Schlumberger and head of their HR for the Middle East. He resigned after attending the 4th funeral of a member of staff. Four separate crews, four different places, all of them members of fracking crews, all of them died of very aggressive cancers. I can’t easily summarise an hours presentation and an equally long film, but I can give you a few choice snippet. Please not very little of this can I substantiate myself, I am simply passing it on, if you want more evidence go look for it on the web.

Did you know that John Browne, the Governments chief advisor on petroleum matters, with a cabinet post to boot, is also a senior executive of Cuadrilla? And that he is not the only government advisor involved in Cuadrilla at a senior level? These people were probably responsible for the government decision that the tax payer will pay to clean up any environmental pollution resulting from shale gas extraction, not the companies responsible for the accident. Isn’t this a carte blanche to do what they like to get the reserves out? In the USA the industry is now effectively deregulated, and the scale of surface and near-surface pollution in parts of Colorado is shocking. Dick Cheyne introduced what is known as the Haliburton Loop hole; which removes all responsibility from the oil industry to report, let alone clean up, and contamination of water as a result of fracking. Apparently waste water from test-drilling in Lancashire has been pumped into the Manchester ship canal, so they are pollution right from the very start of the industry in this country.

The cement casing used to line boreholes, most importantly to line them through aquifers is not as a reliable preventer of leakage of fracking fluids into our aquifers as the oil industry would like us to believe. 50% of cement casings fail over a period of 30 years, 6% fail immediately. The oil industry would probably argue that shale gas wells have a working life rather less than 30 years, but that 6% value is worrying enough. Cement casing failure resulted in both the Piper Alpha accident and BP’s Gulf of Mexico disaster. The statistics for cement failure in fracked wells are probably worse than for conventional drilling because the fracking can trigger cement failure. Even if the oil companies doing the drilling were not using any chemicals dangerous to health, cement failure could permit gas to enter near surface aquifers. Whilst the setting fire to the tap water incident in the film “Gaslands” has been discredited as the gas has been tested and is not from shales being fracked, this does mean that shale gas (“thermogenic” gas) can enter drinking water. There are reports in the USA of people receiving skin burns from their tap water.

Our privatised water companies are very keen to get into bed with the shale gas explorers as they see them as their big new market, because they are going to need so much water. Where is that water going to come from? We don’t have the enormous aquifers or lakes that occur in the USA, and if we did it would be highly damaging to the environment to do so, as has been found in the USA.

The presentation included the film “Dash for Gas” which is a well put together film with some good solid science. If we could get a screening of that locally and give it some real publicity it would be well worth doing. “Gaslands” is not a film I would want to show, as the participants have all been paid off to keep mum. Why? Too much exaggeration in order to get the environmental point across? Attempts by US scientists to reproduce results of events filmed have been stone walled. This is all a great shame, there was no need for such manipulation.

Fracking Leaks - the following I have gleaned from recent scientific articles.

Professor Peter Styles states, in a recent edition of the newsletter of the Geological Society, that contrary to claims by the Shale Gas industry, leakage of methane (the principal gas in shale gas) from extraction, transportation and elivery infrastructure, means that shale gas cannot be considered to have a low carbon footprint. In addition there is now incontrovertible evidence from Duke University (North Carolina) that fracking wells leak. Which leads me onto one reason why shale gas in Western Europe is such a poor prospect. The gas-bearing shales of Western Europe have a higher proportion of natural fractures than do those of N America. It’s not difficult to imagine what happens if a well is fracked and the man-made fractures join up with the natural ones. However this is not deterring the companies such as Cuadrilla, IGas and 3rd Energy, who will take note of this problem only if they loose large amounts of propant fluid and sand. As it is they loose 50% of the fracking fluid into the surrounding rock, and this is considered an acceptable loss, though they are working to reduce it, if only to save money. The other big headache for the Shale Gas industry is people, legislation, high population density in many of the areas with shale gas resources and the environmental movement. We should not underestimate the results of our resistance. I have it straight from the mouth of a geologist working for a major oil company that the anti-shale gas movement will drive the industry offshore, at the moment it is prohibitively expensive, but then so was onshore shale gas extraction 20 years ago….
