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.
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.

What is fracking? How the process works. "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 ...
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 ...
Cabot Oil & Gas , a leading independent natural gas producer with significant operations in the Marcellus, recently announced that it is using natural gas from the Marcellus to fracture wells via ...
The next step is the fracturing itself. A mixture of water and chemical additives are pumped down the well at high pressure. This creates fractures in the rock, and a proppant such as sand is injected to keep the fracture open. This allows the natural gas to flow to the well and up to the surface.
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 ...
