Sentences with phrase «as fracking fluid»

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.

Liquefied petroleum gas (LPG) has a number of advantages over the chemical - laced water typically used as a fracking fluid.

Not exact matches

As the toxic fracking fluids migrate into the local water table, it will add some extra pizazz -LRB-!)

As the gas comes up the well so does the fracking fluid, along with volumes of brine so salty it is hazardous.

That surge has coincided in time and place with the boom in unconventional oil and gas extraction such as hydraulic fracturing, or «fracking,» in which high - pressure fluid is injected into the ground to break up the underlying rock and release trapped gas or oil.

The upshot is a growing — albeit incomplete — list of preferred chemicals that companies such as Apache can choose from as they design their fracking fluids.

It can then be sucked back out as the natural gas is extracted from the reservoir, meaning that there is a virtually complete recovery of the fracking fluid; water - based methods have roughly a 50 percent recovery rate.

A range of hydrocarbons showed up in the deep wells, as did some synthetic organic chemicals associated with fracking fluids and drilling activities.

Fracking has already drawn considerable scrutiny from environmental groups, unhappy homeowners, and teams of lawyers who blame the drilling method for polluting pristine rivers, turning bucolic farmlands into noisy industrial zones, and leaking enough methane to make ordinary tap water as flammable as lighter fluid.

Afterwards, companies need to pump out the fracking fluids, releasing bubbles of dissolved gas as well as burps of early gas production.

The report explains that along with natural gas, production wells in the Azle area of the NEGF can also bring to the surface significant volumes of water from the highly permeable Ellenburger Formation — both naturally occurring brine as well as fluids that were introduced during the fracking process.

Varun Gupta, a scientist with Pacific Northwest National Laboratory's Computational Engineering group, was recently quoted in an article describing an environmentally benign fracking fluid developed for capturing geothermal energy, known as StimuFrac ™.

The 600 - plus - page report that resulted looks at a variety of ways fracking could have an effect on local drinking water: withdrawing millions of gallons of water needed to frack a well, improperly mixing chemicals with the water at the well, injecting that fracking fluid into the ground at high pressure to fracture rock as much as two miles beneath the surface, handling the contaminated water then produced by the well and finally improperly storing or disposing of that water.

But the industry as a whole has been recalcitrant «on this whole question of disclosing fracking fluids,» she said.

George Howard serves as vice chairman of the MEC, and as the chairman of the chemical disclosure committee, which is tasked with creating regulations for frack fluid and other fracking chemicals.

In any case, after the frack fluid is captured, the well is capped with a group of pipes and valves, commonly known as a «Christmas tree,» that direct the gas into into the pipeline and processing system.

During hydraulic facturing, known as fracking, large volumes of fluid are pumped underground to pressurize and break rock, thereby releasing trapped natural gas.

Did fracking fluids ever contain industrial waste mixtures which, if pumped into the ground for non-gas production purposes, would have been regulated as hazardous waste?

The method combines a new form of horizontal drilling with hydraulic fracturing — more commonly known as fracking GThe process blasts open fissures in underground shale - rock formations by injecting a high pressure combination of fluids, chemicals and proppants causing the fossil fuel to flow to the production well.

Some of the fracking fluid remains underground where it could potentially contaminate groundwater in the future, but much of it is brought back to the surface as wastewater.
