List of additives used for fracking
(Redirected from List of additives for hydraulic fracturing)
This article needs attention from an expert in Chemistry. Please add a reason or a talk parameter to this template to explain the issue with the article. (August 2024) |
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 "more environmentally friendly" unconventional hydrocarbon production.[1]
Europe
editIn Europe, Poland, Norway and Germany have the largest reserves of shale gas, and drillings are underway.[2]
United Kingdom
editIn the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids.[3][4][5] Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency[6] while the composition must be disclosed if the regulator demands it.[7] The permitted additives for hydraulic fracturing fluid include polycrylamide, hydrochloric acid and a biocide.

United States
editIn the US, about 750 compounds have been listed as additives for hydraulic fracturing, also known as ingredients of pressurized fracking fluid,[9] in an industry report to the US Congress in 2011[10][11] The following is a partial list of the chemical constituents in additives that are used or may have been used in fracturing operations.[12]

Halliburton Co., which is fighting U.S. EPA about disclosure of its fracking fluid, today announced that it will publicly disclose detailed information on its website about the chemicals used in its fracturing fluids. The Houston-based oilfield services company announced the creation of a new fracturing fluid that uses chemicals "sourced entirely from the food industry."
