I would like to share with you my thoughts on UNCONVENTIONAL onshore gas / oil exploration and extraction (ie fracking), and why I am extremely concerned about this.
I have a sister in the USA who, within the last 18 months, has 12 drill sites within an 8 mile radius of her family home. More permits to drill have been issued and even more are being applied for. A friend is in West Virginia, and he has 17 well sites within a 10 mile radius, again further sites applied for.
Due to this, I've been following the news here in the UK and I hope all the links I've supplied work.
1 Energy Security?
Any gas produced here would be sold into a market connected to the continent, so there would be no guarantee on the price or that it would not be exported to the 'highest bidder'. The companies involved in gas / oil exploration here are backed by massive USA corporations. We have all seen what has happened to our energy costs over the last 10 years, irrelevant what the 'trade' cost of gas has been.

2 Rules and Regulations More Stringent in the UK than the USA?
This is not correct. The reason gas / oil wells leak is due to cementation integrity failure. The cement is the barrier which is meant to prevent the migration of gas / oil / chemicals into the ground / air / aquifers.
According to the Society of Petroleum Engineers figures, 34% of the UK offshore wells have cementation integrity issues.
In the UK the quality controls in place to ensure the concrete casings are of sufficient strength follow industry recognized best practice by the American Petroleum Institute.
Please see this Government link which states this fact (page 18 item B7).
"What quality controls are put in place to ensure concrete well casings are of sufficient strength?
The cement specification, testing of the slurry and placement of it in the well follows recognised industry best practice as contained in the following American Petroleum Institute (API) documents"

Only last month the Environment Agency announced a staffing reduction of 15% by Oct 2014, and this is one of the MAIN agencies that will oversee the unconventional exploration and extraction of gas / oil onshore.
When wells are hydraulically fractured (fracked) seismic activity occurs. This increases the risk to the cementation integrity, further increasing the risk of pollution.
Professor Anthony Ingraffea (Cornell University) worked for 25 years helping to develop hydraulic fracturing of shale for the USA Energy Department. Here are two links which sum up his experience and opinions together with a synopsis of the second linked video:
"Industry wants people to believe that fracking has been going on since 1947, but this form of fracking is very different. There can be 10 or more wells on one pad, collectively using more than 50 million (US) gallons of water and chemicals.
In approx. 2003, the industry chose the current operational method was the best; high volume slick water fracking using multiple wells, clustered pads, long laterals including millions of gallons of fluid and tens of thousands of gallons of chemicals....
Dr Theo Colborn's research shows that 60% of the chemicals used in frack jobs are extremely hazardous to human health.
Industry own data shows that gas wells leak at very high rates; brand new ones are 1 in 20, over time this increases, and up to 50% after 30 years."

3 The productivity of gas / oil wells using unconventional methods (fracking).
Productivity is reduced by approx. 75% in the first year and most wells have a producing life of about 3 years. Therefore, more and more wells have to be drilling just to keep producing the same amount of gas / oil. This in turn leads to higher and higher risks of pollution.

The New York Times released over 400 pages of leaked industry documents supporting this.
www.nytimes.com/interactive/us/natural-gas-drilling-down-documents-4.html
Page 30: QUOTE (abstract) ...'if industry can get Congress behind gas through policy, then the industry has the US by the balls in terms of allowing development to continue as the shale wells that are already drilled rapidly deplete - higher prices, more money for industry, and more dependence on drilling'
Page 427: QUOTE (abstract) ...'when we examine the individual decision of drilling a shale well, I am hard pressed many wells making payout and generating a positive rate of return unless natural gas prices increase significantly'.
- Quantity of wells needed for unconventional onshore gas / oil production.
Nowhere in the world is high pressure hydraulic fracturing happening in such a densely populated country as will be the case in the UK.
To see how many wells are needed to extract shale gas / oil, I would like to point you in the direction of a website:
www.fractracker.org/
On this website you can find maps of USA states where fracking has been happening for up to 10 years. In particular I would like to draw your attention to Pennsylvania and Ohio. These two states combined are a similar size to the UK;
PA + OH = 90,800 sq miles, population approx. 24,300,000
UK = 94,000 sq. miles, population approx. 63,000,000
When you look at the maps of PA and OH, you will see there are LOADS of well sites, and each site (called a pad) can have several drilled wells on it.
5 Infrastructure.
As thousands of wells would be needed to extract the trillions of cubic feet of gas the Government and industry say are beneath our feet, we will need thousands of miles of new pipelines. Each well site will need to be connected to compressor stations to separate the chemicals, silica, water and gas.
The toxic waste (including radioactive waste) also has to be disposed of, which means it will be either re-injected into the ground (further seismic activity / potential pollution) or transported on the roads. None of this is being talked about by the Government or the industry.
Finally, the company that set up in Balcombe was not called Cuadrilla Resources Ltd, (the parent company) but Cuadrilla Balcombe Ltd. Is this perhaps so that there is limited liability and reduced corporate responsibility if things go wrong?
