Please friend me or join my face book Arlington TX Air Quality Odors Log or follow my blog at Barnettshalehell.wordpress.com here is what I know…The UNconventional approach to extracting natural gas is horizontally drilling it from shale bedrock using explosions and enormous amounts of chemical laden water and sand. The old vertical drilling method tapped methane pockets and didn’t use as much water. The new “fracking” technique creates a huge footprint under the ground beneath us and likewise captures more gas which means more money “if” it is a monster producing well or “if” the gas is at $5 to $7 per mmcf (which it hasn’t been for a while now). It costs about $5 million to drill and frack a well. Today they drill many horizontal holes off of one vertical hole and pour cement casing (remember BP’s casing fiasco?) and then they detonate small holes in the casing so that the high pressure water they pump (with sand proppants and chemicals) can reach and fracture the shale bedrock to get the UNnatural gas.
They frack by hydraulically pumping 3-7 million of gallons of our precious water (per well) with silica sand mixed with around 25,000 gallons of toxic chemicals per frack job. These differing “frack fluid recipes” are secret and were protected under the Cheny/Bush administration in 2004 so that it is now exempt from Clean Water Act (the oil and gas industry is also exempt from the Clean Air Act too). This now toxic water mixes underground with radiation, arsenic and heavy metals to name a few. A lot of these fluids do NOT flow back up from the depths they drilled (about 8,000 feet here in the Barnett shale). The toxic fluids that are left down there mix with the “now pulverized rocks” and can migrate to our underground aquifers with the gases. The EPA has a case where a new well communicated with an older well that had casing leaks and reached a drinking water well. The steel casings you see the drilling companies advertising on TV commercials may not withstand earthquakes. What liquids that “do” come back up (daily now for the next 20-30 years) have to be trucked to injection wells (which also have casing “issues” and can foul groundwater). These injection well sites have been in the news lately because they are causing manmade shallow earthquakes.
The old vertical drilling method has damaged surface water too, and with the increase of this UNconventional shale drilling activity brings increases of human error surface spills, chemical fires, pipeline disasters, blowouts, and other emission events (now in urban areas).
This and more (social, health, property values, environmental, farming, fishing, hunting, “COSTS”) is happening in 32 states here in the US. Some towns are seeing a 300% increase in this activity. Ft Worth has 3,000 wells last I checked. Arlington has 70 pad sites with 2 to 22 wells on each pad-site…do the math times 3-7 million gallons of water per well (and each well can be fracked up to 10 times).
Please share this with your friends and start going to your city council meetings and speaking out against fracking too.
