frack, (verb) fracks; fracked; fracking
A new way of extracting natural gas, coal seam gas, or other substances from shale deposits: There are many companies that are fracking into the ground and then they frack horizontally into underground deposits of shale and pump a high-pressure mix of water and chemicals into the well to break apart the rock and release natural gas.

fracking (s) (noun), frackings (pl)
The process of drilling horizontally into underground deposits of shale and then pumping a high-pressure mix of water and chemicals into a well to break apart the rock and release natural gas: Some people are disturbed about fracking activities, not only in the U.S., but also in other countries.

Fracking is a term that comes from hydraulic fracturing or hydro fracking which creates cracking from a wellbore or any hole drilled for the purpose of exploration or extraction of natural resources that is drilled into reservoir rock formations.

There are a lot of people who think fracking is a dirty word.

fracking (adjective), more racking, most racking
A reference to a process that is used to release petroleum, natural gas, coal seam gas, or other substances that are extracted from shale: There can be fracking problems when solid rock is cracked open to squeeze out natural gas because such actions could ruin future plans that some people have regarding the storage of carbon dioxide which is released from burning fossil fuels.

Fracking activities have been blamed for contaminating drinking water, causing small earthquakes and for driving up greenhouse gas emissions or gas that absorbs infrared radiation.

A serious fracking threat could be that carbon dioxide, which is generated by power plants, could not be stored underground because the layers of impermeable caprocks above the storage areas would be poked through with so many fracking holes that they wouldn't be able to form effective seals for any carbon dioxide to prevent leakage back into the atmosphere.

hydraulic fracking (s) (noun), hydraulic frackings (pl)
A process used in nine out of ten natural gas wells in the United States, where millions of gallons of water, sand, and chemicals are pumped underground to break apart the slate rock and release gas: "The explosive growth of hydraulic fracking; especially, in areas where gas is often located closer to people’s homes and population centers has exposed some of the environmental risks associated with shale gas."

"Scientists and environmentalists are worried that the chemicals used in hydraulic fracturing may pose a threat either underground or when waste fluids are handled and sometimes spilled on the surface of the ground."

"Hydraulic frackings involve the injection of more than a million gallons of water, sand, and chemicals at high pressure down and across into the horizontally drilled wells as far as 10,000 feet below the surface of the earth."

"The pressurized mixtures used in hydraulic frackings cause the rock layer of shale to crack and these fissures are held open by the sand particles so the natural gas from the shale can flow up the well to the surface and into storage tanks from where it is taken for distribution and sold to users."

hydro fracking (noun), hydraulic fracturing (noun)
The wings of a fracture extend away from the wellbore (any hole drilled for the purpose of exploration or extraction of natural resources) in opposite directions depending on the natural stresses within the shale formation: "Hydro fracking is a process used to release petroleum, natural gas, coal seam gas, or other substances for extraction, via a technique called induced hydraulic fracturing."

"The process of hydraulic fracturing, or fracking, involves drilling a hole deep into the dense shale rocks which contain natural gas, and then pumping in at very high pressure vast quantities of water mixed with sand and chemicals."

"Hundreds of chemicals are used, some of them potentially toxic, including methanol, naphthalene, benzene, and lead."

"Although hydraulic fracturing has been done since the 1940's, the rapid expansion of its application to unconventional gas production has raised environmental concerns around the world."

"The process of hydro fracking involves water availability, its use and potential contamination, and on greenhouse-gas emissions from shale gas production."

"Many shale deposits are buried under aquifers, and if the cement casing around the wellhole is not adequate, then the process of drilling and fracking can release the chemicals into the aquifer and such leaks of methane can take place, possibly leading to fires or explosions."

"Natural gas is located in densely packed rock; such as, shale and the hydraulic fracturing starts with a hole that is drilled into the shale rock layer, which is not nearly as thick as it is long."

"As soon as the drill reaches the layer of shale rock, it makes a right angle turn and moves horizontally and then the well bore is lined with concrete so it will keep fluids from seeping out and a water and sand mixture is pumped under high pressure down the well bore and into the holes where it fractures the shale."

"Gas in the rock is forced into the well bore and a temporary plug is inserted; and finally, the plugs are drilled out and the gas flows to the surface."

"To summarize, the U.S. federal government is beginning to undertake a review of the chemicals that are used in hydraulic fracturing, the relatively recent technique used to release vast stores of natural gas buried underground."

"The technique uses millions of liters, or gallons, of water, sand, and chemicals; including carcinogens; such as, benzene which is injected at high pressure to fracture the rock and release the stored gas."

"Environmental groups have exposed several persistent dangers: leaks in wells because of faulty casing or migration through layers or rock; breaches in the above-ground tanks that are meant to store used drilling chemicals; and an increase in air emissions."

"Environmentalists are suing the Wyoming Oil and Gas Conservation Commission, saying the regulatory agency hasn't done enough to justify honoring requests by companies to keep the public from reviewing ingredients in hydraulic fracturing fluids."

"Hydraulic fracturing involves pumping water, sand and chemicals into oil and gas wells to crack open fissures. Wyoming has required oilfield service companies to disclose to state officials the ingredients in their fracking fluids since 2010."

"Testing groundwater for fracking-related pollution gets complicated because what goes into fracking fluids isn't generally known outside the companies that make it."
