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.
Donald Trump's energy agenda targets fracking expansion, faster permits and US dominance, sparking debate over economic gains and environmental risks.
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.

The United States Geological Survey notes that fracking involves injecting water into bedrock to loosen it and retrieving oil and gas deposits. What is fracking? How the process works.
On the 40th anniversary of the Clean Water Act, environmental advocates aren't finished with their fight against fracking. A green coalition has banded together to halt hydraulic fracturing in ...
The Barnett Shale is known as an unconventional "tight" gas reservoir, indicating that the gas is not easily extracted. The shale is very impermeable, and it was virtually impossible to produce gas in commercial quantities from this formation until oil and gas companies learned how to effectively use massive hydraulic fracturing in the formation.
