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 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.

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.
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.
Many people have heard the term "fracking" and how it is the future of the U.S. economy, but know very little about what it actually entails. The motivations of the various sides in the debate ...
The various recipes of fracking fluids had been shrouded in secrecy for years. Some say the ingredients are toxic, while others say they are completely safe. About the only thing we know for sure ...
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.
I oversaw the acquisition and operation of 50- to 100-ton truck cranes needed for hydraulic fracking. I also managed work crews who drove pick-up trucks around drill sites checking heavy rubber ...
