Hydraulic fracturing, or «fracking,» is a petroleum - extraction procedure in which millions of gallons of water (as well as sand and chemicals) are injected deep into underground shale beds to crack the rock and release natural gas and oil.

Schwietzke said it's also important to account for the emissions from all the fossil fuels that are produced in a given shale gas field because many wells produce oil, natural gas and other hydrocarbons.

To determine emissions rates at natural gas fields in Pennsylvania's Marcellus shale gas fields, the researchers used emissions data gathered from an airplane that flew over natural gas wells in southwest Pennsylvania in June 2012, some of which were in the process of being drilled.

He said regulators have always thought that there are few emissions during the drilling process, but when drilling rigs drill through shale layers containing a lot of natural gas, a pressure pulse will send gas out of the well and into the atmosphere.

The Howarth paper, «Methane and the greenhouse - gas footprint of natural gas from shale formations,» had estimated that leakage of gas from hydraulic fracturing operations (given that natural gas is mainly methane, a potent heat - trapping substance) and other factors made the climate impact of gas from such wells substantially worse than that of coal, measured per unit of energy.

The Department of Energy's Energy Information Administration has posted a short update on trends in natural gas production in the United States that's worth noting simply because it illustrates the profound nature of the energy transitions that are being propelled by the exploitation of shale deposits using hydraulic fracturing, known best as fracking, along with horizontal drilling.

The advantage of natural gas applies whether it comes from a shale gas well or a conventional gas well.

Indeed, the report challenges a common belief that America's dramatic natural gas boom — made possible by the hydraulic fracturing, or fracking, of shale gas wells — is the main factor in the decline of energy - related emissions.

According to the Natural Gas Annual, gross withdrawals from shale gas wells increased from 5 Bcf / d in 2007 to 33 Bcf / d in 2013, representing 40 % of total natural gas production, and surpassing production from nonshale natural gasNatural Gas Annual, gross withdrawals from shale gas wells increased from 5 Bcf / d in 2007 to 33 Bcf / d in 2013, representing 40 % of total natural gas production, and surpassing production from nonshale natural gas welGas Annual, gross withdrawals from shale gas wells increased from 5 Bcf / d in 2007 to 33 Bcf / d in 2013, representing 40 % of total natural gas production, and surpassing production from nonshale natural gas welgas wells increased from 5 Bcf / d in 2007 to 33 Bcf / d in 2013, representing 40 % of total natural gas production, and surpassing production from nonshale natural gasnatural gas production, and surpassing production from nonshale natural gas welgas production, and surpassing production from nonshale natural gasnatural gas welgas wells.

It's well documented that fracking to produce shale gas generates fugitive methane, which is the main component of natural gas.

Then a mixture, commonly known as fracking fluid, of water (90 percent), sand (9.5 percent) and chemicals (0.5 percent) is pumped into the well under high pressure to create micro-fractures in the shale and free the natural gas or oil.
