Fracking: The good and the bad
Companies that use hydraulic fracturing to retrieve oil and gas from deep underground are changing the U.S. energy picture. Here's a graphic look at the technology and the risks.

Stocks of companies that use fracking -- the popular term for hydraulic fracturing -- have been hot because the technique has resulted in huge gains in U.S. oil and gas production in just the last few years.
But just as hot has been the criticism. Many people see fracking as a threat to underground water supplies, as well as to rivers and streams and air quality above ground. Here's a graphic look at how it works, and the controversy.
I have a question, the diagram shows a plume of chemicals floating up, why doesn't the oil and gas flow up? The reason the oil and gas doesn't flow up is because of the overburden from the rest of the rock and formations above. This is why you frac the production zone, so it can produce the oil and gas through the casing.
This ought to get some laughs!
I once traveled to Ogallala, Neb on business back in 2007 and stopped at a local Mckide's to get a big Mac. I ordered a large coke and the clerk said we only have bottled water. I asked why this was here reply. Our water has become contaminated and we can't sell anything but bottled water. So the water is already bad so how can the keystone pipe line effect it anymore. I laugh every time I see the Dem. on Capitol Hill make remarks about the Ogallala aquifer now. And how the keystone pipeline will harm it, its already polluted.
NEWS BREAK !
It is a scientific fact that deep earthquakes transfer much more energy when shifting a solid rock base.
Deep Hydraulic Fracturing these dense areas makes earthquakes less destructive.
All earthquake prone areas should welcome this technology if for nothing more than saving the children.
The water table is thousands of feet above the fracturing.
If the Progressive Libtards could accept Realville we would all fare better.....
What about those Wind Turbines chopping up birds?.....you Libtard Idiots need to focus.
They only thing that I still don't completely understand is the need to use chemicals...
Is that to set off minor explosions??... Please enlighten..
Because I don't think from 2 miles away we can push/ pressue anything far enough to cause very many cracks in bedrock that far below the surface.?
And what chemicals are they using, again....???
The fracking proponents are quick to point out the multiple layers of concrete and steel in the casings... What about the seal between the casing and the bedrock? As it was explained at a local "town hall" meeting in my area, they calculate the amount of concrete or grout that SHOULD be required to fill the voids between the casings and the bedrock. If the amount of material is substantially more or less, they know they have a problem. REALLY?! That's how we know if the seal is good? They didn't explain what they would do if the amount of material didn't match their calculations.
Anybody have a answer to this one?
