«By measuring naturally occurring ammonium and iodide in numerous samples from different geological formations in the Appalachian Basin, including flowback waters from shale gas wells in the Marcellus and Fayetteville shale formations, we show that fracking fluids are not much different from conventional oil and gas wastes,» said Jennifer S. Harkness, lead author of the study and a PhD student at Duke's Nicholas School of the Environment.

To conduct the new study, the researchers collected and analyzed 44 samples of waters produced from conventional oil and gas wells in New York and Pennsylvania and 31 samples of flowback waters from hydraulically fractured shale gas wells in Pennsylvania and Arkansas.

Until now, estimates of shale gas production have primarily relied on models established for conventional oil and gas wells, which behave differently from the horizontal wells in gas - rich shales.

He estimates that fugitive emissions are only 10 percent of what Howarth and Ingraffea maintain, and that shale gas would indeed be a good replacement for home heating oil and for coal used in power plants.

Energy companies used nearly 250 billion gallons of water to extract unconventional shale gas and oil from hydraulically fractured wells in the United States between 2005 and 2014, a new Duke University study finds.

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.

Now those rules should be extended to shale oil wells and hybrid oil - and - gas wells.

They said it was «very likely» that several thousand weak to moderate earthquakes in recent years were triggered by deep - earth injection of water extracted from the ground as thousands of wells have been drilled into shale oil and gas deposits.

The dramatic rise in shale - gas extraction and the tight - oil revolution (mostly crude oil that is found in shale deposits) happened in the United States and Canada because open access, sound government policy, stable property rights and the incentive offered by market pricing unleashed the skills of good engineers.

This is because they were made well before the current era of shale oil and gas and tight oil and gas development.

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.

Modern hydraulic fracturing combined with horizontal drilling allows multiple wells to be drilled from one spot, reducing the size of the drilling area above ground by as much as 90 percent.4 Fracking is the key to unlocking vast U.S. shale resources, freeing up oil and natural gas that previously was inaccessible while protecting groundwater supplies and the environment.

About 40 percent of the oil and gas wells in parts of the Marcellus shale region will probably be leaking methane into the groundwater or into the atmosphere, concludes a Cornell - led research team that examined the records of more than 41,000 such wells in Pennsylvania.

The problem is that treating oil and gas waste from fracked wells remains particularly tricky because the industry is still allowed to keep secret information about which chemicals drillers use when injecting fluids to crack open shale formations to release oil and gas.

Better yet would be to debate an energy policy for the USA, including opening up exploratory oil and gas drilling including shale deposits, limiting the exponential growth of regulations currently stifling new exploration, ending the EPA regulatory war on coal, reactivating the Keystone pipeline, etc.; these issues have direct impact on American jobs and future energy independence, both of which are more important issues for US voters (and presidential candidates) than any «climate» debate.

Found in limestone and shale deposits, tight oil isn't extracted from wells like conventional oil, but is removed with hydraulic fracturing, or «fracking» — a process that also releases methane, a potent greenhouse gas.
