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 [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 ...
April 17, 2017 – A severed flow line, from a gas well, leads to a gas explosion in a home, killing 2 people, in Firestone, Colorado. [32] [33] May 8, 2017 – Fire broke out at a tank for a fracking well near Greeley. [34] May 25, 2017 – An oil tank explosion and fire in northern Colorado killed a worker, and burned three others.

When Jill Antares Hunkler purchased land in Belmont County, Ohio, in 2007, she never envisioned her home would be surrounded by 78 oil and gas fracking wells a decade later, she said. "I wanted to ...
Hydraulic fracturing has changed the energy scene as a result of many technological advances. Fracking uses both historically-known vertical and horizontal drilling techniques which are used in tandem to extract oil and gas. This process can occur at depths over 10,000 feet deep.
Waterless fracturing is a more expensive process than hydraulic fracturing as propane is more expensive than water. The use of propane necessitates rigorous monitoring, as any leak could potentially lead to an explosion hazard. [2] LPG fracturing was developed by Gastric, an energy company based in Calgary, Alberta, Canada.
In addition, fluids may be used in low-volume well stimulation of high-permeability sandstone wells (20 to 80 thousand US gallons (76 to 303 kl) per well) to the high-volume operations such as shale gas and tight gas that use millions of gallons of water per well.
New drilling in Rancho Palos Verdes has revealed that devastating land movement has been caused, at least partially, by a deeper slip plane — meaning a larger area could be affected.
