What chemicals are used during fracking?
Chemicals Used in Fracking Common ingredients include methanol, ethylene glycol, and propargyl alcohol. Those chemicals, along with many others used in fracking fluid, are considered hazardous to human health.
How many chemicals are used in fracking?
1,084 different chemicals
Despite the fact that most fracking fluid chemicals are considered “proprietary” to the company responsible for the fracking, the EPA has identified 1,084 different chemicals reported as being used in these formulas.
What acids are used in fracking?
The most commonly used fluid in acid fracturing is 15% hydrochloric acid (HCl). To obtain more acid penetration and more etching, 28% HCl is sometimes used as the primary acid fluid.
What chemicals are used in fracking in Australia?
Hydraulic fracturing and the chemicals used
| Service Company Name or Handling Name (links to SDS) | Main chemical components | Main CAS# |

| M300A | Glutaraldehyde | 111-30-8 |
| Clay control | – | – |
| KCL, M117 | Potassium chloride | 7447-40-7 |
What is produced water in the fracking process?
Produced water typically includes salts from dissolution of the underlying rock, naturally occurring radioactive substances, and chemicals added during the drilling and fracking process.
What pressure is used in fracking?
9,000 pounds per square inch
With the fracking well encased in steel and/or cement to prevent leakage into ground water, a fracking fluid is pumped down the well at pressures that can exceed 9,000 pounds per square inch (psi) or 62,050 kilopascals (kPA).
What is in fracking liquid?
Fracking fluid is 99.5% water and sand. 0.5% is made up of safe chemical additives, most of which are found in common household products, like toothpaste and makeup remover, or in the foods you eat.
What liquid is used for fracking?
In general, hydraulic fracturing fluid is composed of water, proppant (typically sand), and chemicals. A public website known as FracFocus has been established by industry that lists specific materials used in many, but not all, hydraulically fractured wells.
What does hydrochloric acid do in fracking?
Acidizing involves pumping acid (usually hydrochloric acid), into the formation to dissolve some of the rock material to clean out pores and enable gas and fluid to flows more readily into the well. Some studies have shown that more than 90% of fracking fluids may remain underground.
How many fracking wells are in Australia?
Did you know: it is estimated there will be 40,000 coal seam gas wells in Australia.
What is in the wastewater from fracking?
But the dramatic growth of shale gas over the past decade, made possible by hydraulic fracturing, or fracking, has led to huge volumes of salty wastewater called brine or produced water.
What kind of acid is used in fracking?
Acids like hydrochloric acid are used in fracking fluids to dissolve the minerals in the rock, soil and sand below the ground. Acid is also used to dissolve parts of the rock to initiate cracking, according to FracFocus.
Why does fracking use diethanolamine in fracking?
Diethanolamine or DEA is among organic compound that is soluble in water and colorless. Those reasons are why fracking uses it as one of the chemicals needed. Eventhough the chemical is soluble, it does not guarantee the chemical to be safe. Research found diethanolamine to be highly toxic and considered carcinogenic.
What chemicals are toxic in fracking?
The first chemical that is toxic in fracking is acetaldehyde. Acetaldehyde is an organic compound with formula CH3CHO. This chemical occurs naturally in coffee and bread as well as ripe fruit. Despite being organic compound, it does not guarantee the chemical to be toxic free and safe.
What is hydraulic fracturing?
Hydraulic fracturing (also known as hydrofracturing, hydrofracking, or fracking) involves injecting shale formations with pressurized fluids to release trapped oil and gas reserves. The fluid used for this purpose is a mixture of water, sand, and a variety of chemicals.
