List of additives used for fracking

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.

In Europe, Poland, Norway and Germany have the largest reserves of shale gas, and drillings are underway.

In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency while the composition must be disclosed if the regulator demands it. The permitted additives for hydraulic fracturing fluid include polycrylamide, hydrochloric acid and a biocide.

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