Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
Modern day fracking equipment is capable of pumping anywhere from 800 to 4200 gallons of water per minute, at pressures ranging from 500 to 20,000+ psi. [172] Once the injection process is complete and gas has entered the well, anywhere between 10 and 30 percent of the fluid injected will flow back into the well as wastewater for disposal.
Hydraulic fracturing (fracking) and acidizing are two of the most common methods for well stimulation. These well stimulation techniques help create pathways for oil or gas to flow more easily, ultimately increasing the overall production of the well. [1] Well stimulation can be performed on an oil or gas well located onshore or offshore.

Hydraulic fracking without the water? Photo credit: Flickr/Snap Opponents of hydraulic fracturing have many criticisms of the process. From the chemicals injected into the ground to the heavy ...
"This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures in order to extract trapped oil and gas," read the United ...
Fracking in Canada was first used in Alberta in 1953 to extract hydrocarbons from the giant Pembina oil field, the biggest conventional oil field in Alberta, which would have produced very little oil without fracturing. Since then, over 170,000 oil and gas wells have been fractured in Western Canada.
The process of fracking- in its latest iteration - is a game-changer. Those in favor of the controversial method of extracting oil and natural gas point to its potential to lower energy costs and ...
