In 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]
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.

The EPA responded with a study of potential and actual impacts of hydraulic fracturing of coalbed methane wells on drinking water, published in 2004. Section 7.4 of the report "concluded that the injection of hydraulic fracturing fluids into coalbed methane wells poses little or no threat to USDWs and does not justify additional study at this ...
Drilling and hydraulic fracturing have made the United States a major crude oil exporter as of 2019, [11] but leakage of methane, a potent greenhouse gas, has dramatically increased. [ 12 ] [ 13 ] Increased oil and gas production from the decade-long fracking boom has led to lower prices for consumers, with near-record lows of the share of ...
2009: First hydraulic fracturing of a horizontally drilled well in New Brunswick in the McCully area. [59] 2009: Start of exploratory drilling and hydraulic fracturing in the Elgin area, south of Petitcodiac. [59] 2009–2010: The first shale-targeted wells are drilled in New Brunswick – four wells in the Elgin area, south of Petitcodiac.
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 ...

Germany also had the largest hydraulic fracturing jobs in Europe, using up to 650 tonnes of proppant per well. Most German fracs used water- or oil-based gels. [34] The most popular target formation for hydraulic fracturing was the Rotliegend Sandstone. Hydraulically fractured wells are today the source of most of German natural gas production.
