However, the shale rock containing natural gas is separated from underground water aquifers by impermeable layers of rock that do not allow any hydraulic fracturing fluids to migrate into underground water aquifers.

Of course, the fly in the natural gas ointment is fracking, the hydraulic fracturing of underground rock to extract more gas and oil.
Over the past few months, cash strapped Chesapeake Energy has faced several headwinds as its leadership team misgoverned and aggravated the operations already marred by rock-bottom gas prices.

There has been turbulence in businesses associated with coal as coal has lost its vigor lately as the preferred fuel option for electricity generation in the U.S. amid rock bottom natural gas prices.
Rock-bottom gas prices are already fueling a surge of new manufacturing activity in the U.S. Consumers, from big utilities to condo buildings in New York, are also converting to burning the cheap new gas.
This year he completed what is believed to be the first ever fracture stimulation procedure in Turkey: injecting a mixture of water and sand at high pressure down the wells to break up rock and release gas.
Mulva talked up the potential of drilling gas out of shale rock, saying that new recovery techniques boost the potential global gas resource to more than 38, 000 trillion cubic feet centuries of supply.
Fracking involves drilling a borehole before a high-pressure water mixture is directed at the rock to release the gas.
Fracking is a technique of shale gas extraction that involves pumping water and chemicals into shale rock at high pressure to extract gas.
In cases where the mass is known, scientists can determine the density, ultimately hinting at the internal structure (gas, rock and so on).

The assertion is that hydraulic fracturing fluids, which are injected at high speed and high pressure to create cracks in the shale rock that traps natural gas, will seep into underground water aquifers.

The EPA has subpoenaed Halliburton for the secret formula for the liquid chemical cocktail it pumps into underground rock structures so natural gas can be accessed through a process known as hydraulic fracturing or fracking.
The industry has boomed in recent years, thanks to a stunning expansion of drilling in previously untapped areas because of the use of hydraulic fracturing, or fracking, which injects sand, water and chemicals to break apart rock and free the gas inside.
The drilling technique, which uses sand, water and chemicals under high pressure to extract oil and natural gas from rock formations, has helped Eagle Ford oil production grow by 184% last year compared with 2011, according to the Railroad Commission of Texas, which regulates the state's oil and gas exploration and production.
At first glance, it might seem obvious that it was through the action of flowing water (fluvial), but the Curiosity team needs to rule out the possibility that these rocks were deposited by the wind (aeolian) or by some kind of surge, such as the fast-moving clouds of gas and rock that will often plummet down the sides of particular types of volcano (a pyroclastic surge).
Recent discoveries of immense amounts of natural gas trapped in shale rock, coupled with the development of new technologies to capture and produce such shale gas, are driving natural gas prices down.
Unlike the normal gas extraction, chemically treated water is forced upon the rock underground to fracture it releasing the gas in the process.
Gas does now contribute 35% to power generation, but rock-bottom prices and a sniffiness about gas as oil's poor relation mean that exploiting its bounty (Saudi Arabia apparently has the world's fifth-largest gas reserves) has proven hard.
The technique involves pumping fluids into a well to recover natural gas from shale rock.
BBC: China firms to invest $2bn exploring shale gas reserves
Shale gas is extracted by tapping gas from shale rock using a process called hydraulic fracturing, or fracking.
And they have deployed technologies like hydraulic fracturing, or fracking, and horizontal drilling to produce gas from shale rock.

Lord Whitty also said he was "suspicious" of fracking, a controversial process used in capturing gas from shale rock.
China has some of the largest reserves in the world of shale gas, which is gas trapped in rock formations.
Fracking is a drilling process that frees gas from deep rock deposits by injecting wells with chemical-laced water at high pressure.
Fracking is the process of blasting water at high pressure into shale rock to release oil or gas held within it.
In fracking, a mixture of water, sand and some chemicals is pumped into a well under high pressure to force the gas from the rock.
Hydraulic fracturing, or fracking, pumps millions of gallons of water mixed with fine sand and chemicals deep into oil and gas wells to crack gas-bearing rock.
Fracking, or hydraulic fracturing, has unleashed a boom in energy production in the United States by allowing the extraction of oil and gas from shale rock.
The potential for an energy industry based on the region's prime location atop the gas-rich rock formation known as the Marcellus Shale also has drawn enthusiasm and stirred debate.
