FAQs

What process is also known as hydraulic fracturing? ›

Hydraulic fracturing, commonly known as fracking, is the process of injecting water, sand, and/or chemicals into a well to break up underground bedrock to free up oil or gas reserves.

Hydraulic fracturing has been a commercial process in the international oil and gas industry since 1947. Historically, hydraulic fracturing involved pumping a small amount of fluid under relatively low pressure into a targeted conventional rock formation to open up small gaps in the rock to increase oil and gas flow.

"Fracking" is short for "hydraulic fracturing" — it's a process by which water, sand, and chemicals are injected underground at very high pressures to crack open rock layers and release the oil or gas trapped inside.

The process creates vast amounts of wastewater, emits greenhouse gases such as methane, releases toxic air pollutants and generates noise. Studies have shown these gas and oil operations can lead to loss of animal and plant habitats, species decline, migratory disruptions and land degradation.

Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth.

Hydraulic fracturing, or “fracking” as it is more commonly known, is just one small method of the broader process of unconventional development of oil and natural gas. Fracking is a proven drilling technology used for extracting oil, natural gas, geothermal energy, or water from deep underground.

Hydraulic fracturing, or fracking, is a process that uses high-pressure fluid injections to shatter rock formations and extract natural gas. Fracking has been blamed for leaking millions of tons of methane, a greenhouse gas more potent than carbon dioxide.

Hydraulic fracturing might pose public health threats to people who live near the wells or are exposed to water contaminated with fracking chemicals or gas. There are claims of headaches, nosebleeds, disorientation, fainting, sick animals, and development of cancer and other chronic diseases.

Hydraulic fracturing produces fractures in the rock formation that stimulate the flow of natural gas or oil, increasing the volumes that can be recovered. Wells may be drilled vertically hundreds to thousands of feet below the land surface and may include horizontal or directional sections extending thousands of feet.

Fracking is a temporary process that occurs after a well has been drilled and usually takes only about 3-5 days per well. Sometimes, wells are re-fracked to extend their production, but the energy each well can produce may last for 20 to 40 years.

Does fracking ruin well water? ›

Hydraulic fracturing can and does contaminate groundwater. This was suspected for decades and eventually proven true. In fact, a 1987 report concluded that drinking water contamination had been detected since 1984.

These three resources are pumped and then separated above the surface. Tanks hold and transport the oil and natural gas resources through pipelines that expand across the country providing communities energy. Oil and natural gas production of one well can last up to 20-30 years.

Water quality is a primary concern because the hydraulic fracturing fluids used to fracture rock formations have chemicals that could harm human health and the environment, especially if they enter drinking water supplies. Other concerns relate to chemicals that are recovered and disposed of as wastewater.

Most fracking wells in use today rely on two technologies: hydraulic fracturing, which has been in use since the 1940s, and horizontal drilling, a technique that first became widespread in the 1990s, according to Columbia University's Earth Institute.

Fracking is essential for the production of natural gas and oil from shale formations, and with advances in fracking technology, it is becoming easier and more accessible to access natural gas.

Hydraulic fracturing, or fracking, is a technique for recovering gas and oil from shale rock. It involves drilling into the earth and directing a high-pressure mixture of water, sand and chemicals at a rock layer, to release the gas inside.

Shale Oil, Shale Gas, and Hydraulic Fracturing

There are three types of hydraulic fracturing: (1) water-based hydraulic fracturing, (2) foam-based fracturing fluids, and (3) cryogenic fluid, liquid CO₂.

What is an alternative to natural gas fracking? ›

Some experts say fracking alternatives like wind and solar power are more economically and ecologically efficient. Wind and solar power costs are much lower because of how you source them. Also, they don't bring the harmful effects fracking can bring.

Researchers have linked fracking and related processes, called “unconventional natural gas development,” to higher odds for birth defects and certain types of cancer. A link doesn't prove cause and effect.

However, human activities are more likely the source. Any sort of groundwater pumping, leaking pipes, water injection, or concentrated water flow can cause sinkholes to form — as can digging through soil, which includes drilling and therefore, fracking.

Groundwater becomes contaminated by hydraulic fracturing in a number of ways, including leakage from liquid storage areas, leakage from injection wells, leakage during hydrofracking along faults or up abandoned wells, seepage into the ground when wastewater and residuals are applied to land (i.e. used for irrigation or ...

The most common causes of poor hydraulic performance are particulate contamination, water contamination, clogged filters, high fluid temperature and incorrect hydraulic fluids.

Air and Water Contamination

Air and water contamination are the leading causes of hydraulic failure, accounting for 80 to 90% of hydraulic failures. Faulty pumps, system breaches or temperature issues often cause both types of contamination.

The only water treatment usually necessary is filtration. This can be as simple as “sock” filters or as extensive as clarifiers depending on the solids loading. If no deep wells are available, the preferred method of disposal is reuse. The frack water will be blended with fresh water and used at another site.

Fracking is expensive, but still less costly than the methods used to obtain oil from the wells mentioned above.

Many hydraulic fracturing operations use “injection” wells to dispose of contaminated fluids. These concrete-encased wells reach thousands of feet underground and can store waste liquid from multiple fracking operations.

Why casing failures occur. Casing failures occur because of a lack of pressure: the steel or cement lining a well fails, allowing whatever happens to be in the well at the time to escape. Sometimes, it's deadly methane gases. Other times, it's the water and natural gas from a fracking operation.

How often does fracking go wrong? ›

Up to 16% of hydraulically fractured oil and gas wells spill liquids every year, according to new research from US scientists. They found that there had been 6,600 releases from these fracked wells over a ten-year period in four states.

Proppant use and intensity of hydraulic fracturing have also increased, resulting in huge increases in well performance. This evolution has led to significantly higher well cost (on average greater than 6 million dollars (MM$)/well).

Calculated as a percentage of production, the fracked wells were far less leaky. The conventional wells ranged from 0.35 percent to a nightmarish 91 percent for an average of 10.5 percent leakage. The fracked wells, meanwhile, average 0.13 percent leakage with a max of just 1.2 percent.

Water use per well can be anywhere from about 1.5 million gallons to about 16 million gallons.

FACT: Fracking does NOT Contaminate Drinking Water

The report found that there is “no evidence of widespread, systemic impacts on drinking water” as a result of the fracking process.

25. One well can be fracked up to 20 times. Once a well is ready for fracking, it can be a long-term source of natural gas. According to fracking facts, it's possible to frack a single well up to 20 times.

“The drilling comes first and then the fracking.” Wells are drilled straight down to depths ranging from 6,000 feet to more than 14,000 feet, cutting through dozens of geological layers, including pockets of drinking water.

Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.

Fracking releases large amounts of methane, a dangerously potent greenhouse gas. Fracked shale gas wells, for example, may have methane leakage rates as high as 7.9 percent, which would make such natural gas worse for the climate than coal. But fracking also threatens our climate in another way.

Millions of energy jobs would be lost. Heavy energy users in steel, food processing, information management, the travel industry and manufacturers across the board would lose (and do) due to higher energy prices.

Does fracking cause loud booms? ›

Hydraulic fracturing, or fracking, is a means of natural gas extraction employed in deep natural gas well drilling. And yes, sometimes it causes loud noises. But the idea that fracking is causing the booms is unlikely, if not impossible.

The process creates vast amounts of wastewater, emits greenhouse gases such as methane, releases toxic air pollutants and generates noise. Studies have shown these gas and oil operations can lead to loss of animal and plant habitats, species decline, migratory disruptions and land degradation.

It risks causing pollution and harming health

Not only is fracking bad for our climate, it risks causing air, water and noise pollution. It uses toxic chemicals that may not be regulated well enough. An accident could mean that these chemicals leak into water supplies or cause pollution above ground.

Vermont, which has no known frackable gas reserves, banned fracking preventatively in May 2012.

1. Texas. Texas is situated over parts of numerous basins (Anadarko, Palo Duro, and Permian) and shales (Barnett, Eagle Ford, and Haynesville-Bossier). At the end of the 20th century, when natural gas was giving Texas its second oil boom, Anadarko Basin provided the largest output of natural gas anywhere in the U.S.

Fracking has been documented in more than 30 U.S. states and is particularly widespread in North Dakota, Pennsylvania and Texas. And it's expanding into new areas, making states like California, New Mexico and Nevada increasingly threatened by a potential fracking boom. 2. How does fracking contaminate our water?

Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.

Open loop hydraulic system and closed loop hydraulic system are the two types of hydraulic system.

Hydrochloric acid (HCl) is the single largest liquid component used in a fracturing fluid aside from water; while the concentration of the acid may vary, a 15% HCl mix is a typical concentration.

Horizontal Drilling

What makes drilling for hydrocarbons in a shale formation unique is that it is necessary to drill horizontally. A well is drilled vertically to the right depth called the 'kick off point', and at this point, the well bore begins curving to become horizontal.

Is fracturing a method of natural gas extraction also known as fracking? ›

Hydraulic fracturing, or fracking, is a method used to extract natural gas and oil from deep rock formations known as shale. Using this method, drilling operators force water, sand, and a mix of chemicals into horizontally drilled wells, causing the shale to crack and release natural gas or oil.

Fracking is short for "hydraulic fracturing", which is the process of creating fractures in rocks and rock formations by injecting specialized fluid into cracks to force them to open further. The larger fissures allow more oil and gas to flow out of the formations and into the wellbore.

Gear, vane, and piston are the three classifications of hydraulic motors. Gear and vane motors are simple rotating systems with advantages like low cost and high rpm.

The major components that make up a hydraulic system are the reservoir, pump, valve(s) and actuator(s) (motor, cylinder, etc.).

Water used for hydraulic fracturing is typically fresh water taken from groundwater and surface water resources. Although there are increasing efforts to use nonpotable water, some of these sources also supply drinking water.

Fracking has been blamed for leaking millions of tons of methane, a greenhouse gas more potent than carbon dioxide. Fracking is also associated with other airborne hydrocarbons that can cause health and respiratory issues. Fracking uses large amounts of water, which can become contaminated and affect local groundwater.
