The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...
In the US, except for diesel-based additive fracturing fluids, noted by the American Environmental Protection Agency to have a higher proportion of volatile organic compounds and carcinogenic BTEX, use of fracturing fluids in hydraulic fracturing operations was explicitly excluded from regulation under the American Clean Water Act in 2005, a ...
The proposed act would have required the energy industry to disclose the chemical additives used in the hydraulic fracturing fluid. The gas industry opposed the legislation. [1] The bill was introduced to both houses of the 111th United States Congress on June 9, 2009.
Once the injection process is complete and gas has entered the well, anywhere between 10 and 30 percent of the fluid injected will flow back into the well as wastewater for disposal. In addition to the chemical additives present in fracking fluid, flowback water contains dangerous volatile hydrocarbons, such as H 2 S pulled from the fractured ...
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 [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 ...
In fracking, slickwater is a hydraulic fracturing proppant primarily composed of 98–99.5% water and sand, with 0.5–2% chemical additives. These additives reduce friction, prevent corrosion, inhibit microbial growth, and improve fluid flow. Injected at high pressure, slickwater creates fractures in rock formations, enhancing oil or gas ...
