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 ...
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.
Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.
Hunkler's three-acre property at the headwaters of the Captina Creek Watershed was one of hundreds in the area that she said became a magnet for fracking. Fracking is being forced onto some Ohio ...
"Hydraulic fracturing is a well-stimulation technique used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from ...
Hydraulic fracturing, or fracking, has been around for a long time. However, it wasn't until the last couple of years that it became truly revolutionary in terms of oil and natural gas production.
Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, particularly from unconventional reservoirs.

A hydraulic fracturing operation at a Marcellus Shale well. After a flow path is made, acids and fracturing fluids may be pumped into the well to fracture, clean, or otherwise prepare and stimulate the reservoir rock to allow optimal production of hydrocarbons into the wellbore. Usually the area above the producing section of the well is packed ...
