Well first off, I don't believe fracking will kill us all.
After all it's been used for more than 60 years and has been safe during that entire time.
It's true. There is no proof that fracking hurts us.
The depth of the surface casing is generally determined based on groundwater protection, among other factors.
As the well is drilled deeper, additional casing is installed to isolate the formations from which oil or natural gas is to be produced, which further protects groundwater from the producing formations in the well.
Fracking has been used in more than one million U.S. wells, and has safely produced more than seven billion barrels of oil and 600 trillion cubic feet of natural gas.
In addition to enhancing our domestic energy supplies, shale development has irrefutable economic benefits.
Hydraulic fracturing in the Marcellus and Barnett Shale has boosted local economies—generating royalty payments to property owners, providing tax revenues to the government and creating much-needed high-paying American jobs.
Engineering and surveying, construction, hospitality, equipment manufacturing and environmental permitting are just some of the professions experiencing the positive ripple effects of increased oil and natural gas shale development.
Some opponents of oil and natural gas production claim that fracking has serious environmental consequences.
Fracking's Track Record
The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators.
Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
Studies estimate that up to 80 percent of natural gas wells drilled in the next decade will require hydraulic fracturing technology.
In fact, EPA Administrator Lisa Jackson recently testified that she was “…not aware of any proven case where the fracking process itself has affected water.”
Fracking makes it possible to produce oil and natural gas in places where conventional technologies are ineffective. Access to new wells encourages economic growth and provides energy for all Americans.
The oil and natural gas industry is committed to the continued safe and responsible development of our domestic resources and ensuring that the public is part of the conversation.
Let's let's talk about ground-water contamination and how it "could" take place.
I have two very deep water wells on my property. One is at almost 3oo feet and the other is at almost 400 feet down.
They are very deep in comparison to water wells in the San Joaquin Valley and the San Francisco Bay Area towns like say Livermore.
If there were oil drilling in my area, say right next door to my property, even at the depths of my wells, my ground-water would be safe from contamination.
The reason is that though water accounts for about 90 percent of the fracturing mixture and sand accounts for about 9.5 percent - which means that chemicals account for the remaining .5% (one half of one percent) of the mixture - the fracking process is taking place too deep for it to effect my wells.
"It's our experience in Pennsylvania that we have not had one case in which the fluids used to break off the gas from 5,000 to 8,000 feet (1,500-2,400 m) underground have returned to contaminate ground water."
-- John Hanger, former Secretary of the Pennsylvania Department of Environmental Protection.
That's right! We're talking about wells that extend 5,000 to 8,000 feet beneath the earth!
To give you an idea of how deep that really is, imagine this:
On November 17th, 2011, Shell Oil Company broke its previous record for the world’s deepest underwater well.
Shell says it has started producing oil from a well 9,627 feet below the surface of the Gulf of Mexico.
That depth is more than six times greater than the Empire State Building’s height.
Let's Look At The Well Construction For A Moment - and where water contamination "could" come from.
And yes, all oil and gas wells use piping, sleeves and concrete when putting in a well - whether its a conventional well of one used in a fracking.
It's simply a part of the construction process of putting in an oil or gas well - for fracking or not!
Here's a short video about the process of Drilling an Oil Well, its construction.
1) How the construction of the well piping to ensure no contamination enters the water tables close to the surface;
2) How the oil enters the well pipe - it does so through a perforated pipe.
This method has been used longer than most can remember; the only difference between a standard well and once used with a fracking method is the introduction of high pressure fluid to open the ground to allow more oil to be gathered.
3) Note the safeguards and safety measures that the video shows are put in place before any oil or gas can be pumped out of the ground;
4) And please note the fact that this video comes from the extremely liberal State of California.
Since underground water runs on plates and sideways, the only way my ground-water could become contaminated is if there were a problem with the casing, the piping and sleeves, and the concrete put into place to protect the ground-water.
Environmental extremists accuse fracking of causing earthquakes, sinkholes and all other sorts of calamities.
