As of March 2013 there was only one known fracking well in Illinois, located in White County.
On August 29, 2014, the Illinois Department of Natural Resources released a set of rules that will govern fracking in Illinois. These rules are based off legislation passed by the Illinois General Assembly in 2013, over 35,000 public comments, and five public meetings that were held across the state. The final step needed for the rules to take affect occurred on November 6, 2014, when the Administrative Rules Committee approved the rules. As of November 6, 2014 oil and gas drillers can apply for permits that allow wells to be fracked in Illinois. Those opposed to fracking have pledge to resist these rules. According to one environmentalist at the hearing where the rules were approved, "'we will resist this with our bodies, our hearts and our minds. We will block this, we will chain ourselves to trucks.'" As stated by the Chicago Tribune, the process for getting these rules approved was "long and tortured." A final version of these rules can be found here.

Hydraulic fracturing, or "fracking," is the process of injecting fluid--mostly water and sand, but with additional chemicals--into the ground at a high pressure to fracture shale rocks and release the oil and natural gas inside.
Recent technological advances in oil and gas drilling--horizontal drilling and hydraulic fracturing--have created a wealth of opportunities and challenges for states with fossil fuel reserves that can be accessed through the combination of these two technologies. The increased use of fracking has been an economic boon for many states, not only those with fracking, but also those with supporting industries, such as frac sand mining or associated machinery manufacturing.
Opponents of fracking argue that the potential negative environmental and human health impacts could be significant. Although wells have been fracked for over 65 years in the United States, concerns have been raised about whether federal, state and local regulatory agencies can keep up with the recent rapid increase in fracking activity, and adequately protect the environment and human health. As with any type of energy extraction, either traditional or renewable, there are economic, environmental and political tradeoffs.
Since 1853, oil and natural gas drilling has been occurring in Illinois. Illinois has produced 4 billion barrels of oil and 4 trillion cubic feet of natural gas since production began. From 1940-1950 the Illinois Basin, a fossil fuels repository stretching from southern Illinois to northwest Kentucky and southwest Indiana, was the third largest oil producing basin in the United States. Production fell sharply after World War II, but the creation of new drilling technologies--horizontal drilling and hydraulic fracturing--has made drilling for once uneconomical oil and natural gas reserves possible. Currently most wells in the state that are still producing oil are only producing 2 barrels of crude oil a day.
On February 26, 2014 the Illinois Department of Natural Resources (IDNR) issued a permit that would allow Strata-X to drill a test well totaling no more than a true measured depth of 9,300 feet.
Areas of activity
Below southern Illinois is the Illinois Basin Province. There are several large oil producing formations including Clay City, Salem-Louden Anticlines, DuQuoin Monocline and La Salle. Oil was discovered in the Illinois Basin in 1866 in Litchfield. Major production from this basin began in 1905. There have been three waves of production in this basin. The first was from 1905-1910. The development of exploration techniques led to another wave from 1930-1940. The third wave occurred in 1950 with the development of fracking.
- The Post-New Albany Play contains both oil and natural gas, although oil makes up a majority of the recoverable reserves, and covers 34,000 square miles. The shale rock in this formation is more than 460 feet thick. The Post-New Albany play is a mature play and accounts for more than 95 percent of the production within the Illinois Basin. Despite its age, or maturity, the play is expected to have more than one million barrels of oil left.
- The Hunton Play contains oil and natural gas and covers 29,000 square miles. This play has yielded 150-200 million barrels, or about 4 percent, of the oil produced from the Illinois Basin. Further development is limited by the quality remaining in the reservoirs. The two largest fields in this play are expected to have 22 million barrels of oil.
- The Silurian Reef Play includes oil and carbonate reserves and covers 35,000 square miles. The fields in this play contain less than 5 million barrels of oil, although the largest two fields have an estimated 29.8 million barrels. This play is very mature and there is little chance of finding new fossil fuel resources.
- The Middle and Upper Ordivician Carbonate Play has produced oil and some natural gas. This play has limited future development.
- The Rough Creek Graben Play is still considered to be hypothetical and requires more exploration.
- The Pre-Middle Ordovician Play is another hypothetical play. There has been some testing of this play and some hydrocarbons were recovered, but nothing with commercial potential.
- The New Albany Shale Gas Play is a hypothetical play. The New Albany Shale formation is 350 million years old, and could lead to the production of 300 billion barrels of oil. This play is generating much attention because of the possible reserves it holds.
Coalbed gas play
- In the Central Basin Play some gas has been found in abandoned coal mines, and other shallow locations, but no major drilling has occurred. The reserves in this play are considered to be moderate to poor. More infrastructure is needed before more development of this area can occur.
The use of fracking, often in combination with horizontal drilling, has made it possible to extract supplies of oil and natural gas that were once economically unfeasible to extract. This has led to significant growth in the domestic oil and gas industry, and in the supply of domestically produced oil and natural gas. The growth in activity has impacted the economy in direct ways, such as increased capital investments (from both the U.S. and other countries), royalty and lease payments, and government revenues in the form of fees and taxes. The increased supply of natural gas and oil has also affected electricity prices, manufacturing, service industries and employment. In many places, fracking has increased employment in the mining (oil and gas) sector and supporting industries, such as the restaurant and housing sectors. Consumers and manufacturers have also benefitted thus far from lower oil and natural gas prices, and increased demand for pipeline, drilling and other ancillary equipment. As demand for natural gas and oil grows, however, prices are expected to rise.
Taxes, fees and revenue
Fracking booms can increase local government revenue through increases in property and sales taxes, which can help compensate for the costs detailed below. The primary revenue streams from fracking--mineral leasing revenues and severance taxes--go to state and federal governments.
Under the Hydraulic Fracturing Regulatory Act those applying for a fracking permit must pay a non-refundable fee of $13,500 per application. A portion of this fee, $11,000, of this fee goes to the Mines and Minerals Fund and the remaining amount goes to the Illinois Clean Water Fund. Both funds support the regulation and environmental protection of areas under their respective agency's authority. Wayne County reported $200,000 in revenue oil and gas exploration companies from 2011-2012 from fees paid to the county for processing records.
Royalties and land sales
The United States is one of the few countries where property owners can own the right to use and build on their land, known as surface rights, but they may not own the rights to the minerals located under their property. Depending on the state the mineral rights may have been sold in the past and may now belong to someone other than the surface owner. In fact, those mineral rights may belong to more than one individual, a company, or many individuals, who now have the right to extract those minerals, and in some states this can happen without the permission of the property owner. This can cause tension between the mineral owner, or whoever is leasing the mineral rights, and property owner. In 2012 there were reports of leasing payments ranging from $75-$250 per acre, with a 15 percent royalty payment.
Economic impact studies
Below are studies about the economic impact of the oil and natural gas industry (also categorized as the mining industry in some studies) in Illinois. Both the author(s) and sponsor(s) of the studies have been listed.
Study for the American Petroleum Institute
|IMPLAN and REMI are two econometric modeling systems used in both the private and public sectors to predict economic outcomes of policy changes. While these systems are widely used and highly respected, their results are theoretical and may not be universally accepted.
Because the oil and gas industry has grown so rapidly, there is not a wealth of data regarding its economic impacts. Instead economists use forecasting models, such as IMPLAN and REMI, to predict the impact increased fossil fuel extraction is having on the economy. These studies usually measure both direct impacts, i.e., the jobs and income being added within the oil and gas industry, and indirect impacts, i.e., jobs created throughout the supply chain. These studies also include induced impact, i.e., jobs created through increased spending due to growth in the industry.
The following data are taken from a study done by PricewaterhouseCoopers LLP (PwC), a research consulting firm, for the American Petroleum Institute about the economic impact of the oil and natural gas industry in 2011. According to the PwC study, the oil and gas industry added $33.31 billion in total value in 2011, including direct, indirect and induced value. Of this, $13.64 billion, or 2.1 percent of the state's total value added, was direct, $9.49 billion was indirect and $10.17 billion was induced, totaling 5.1 percent of the state's total value in 2011.
Fracking is not occurring on a large scale in Illinois and as such the economic impacts have been relatively small. There is however much speculation on the potential economic impact of fracking in Illinois. Because of the potentially large reserves in the New Albany Shale there have been some land lease sales and royalty agreements made between mineral right owners and oil and gas companies. In order to find out who owns the mineral rights for land, oil and gas developers are sending landmen to counties to research these rights, which can result in fees for county governments.
A study from a free-market think tank, The Heartland Institute, projects full-time employment to increase by 1,034 to 47,312 jobs between 2013 and 2018, depending on the level of investment in the state by oil and gas companies. This figure includes direct, indirect and induced jobs. This study also projects the total economic impact to the state to range from $207.8 million to $9,509.3 million, also depending on investment from oil and gas companies.
The chart on the right shows employment in oil and gas extraction, drilling oil and gas wells, and support activities for oil and gas operations in Illinois and the United States. According to the Illinois Department of Employment Security, between 2005 and 2012 employment in these areas increased by 30-40 percent.
The PwC study attributes 263,727 jobs, or 3.6 percent of state employment in 2011, to jobs created directly, indirectly, or induced from, the oil and natural gas industry. The industry directly employed 65,175 people, or 0.9 percent of state total employment. Indirectly the industry employed 81,766 people and induced 116,786 jobs.
Direct, indirect and induced labor income, according to this study, was $15.74 billion, totaling 3.8 percent of the state's labor income in 2011. Direct labor income from the mining sector was $3.9 billion, or 0.9 percent of the state's total. Indirect labor income totaled $5.88 billion and induced labor income was $5.97 billion.
Because of the sudden and unprecedented growth in fracking across the United States, getting high-quality, unbiased, state-specific information on the environmental impacts of fracking can be difficult. Most studies that would fit those first two qualifications are government studies that focus on the nation as a whole. As such, much of the information that follows in this section may only apply generally to the state. State-specific information has been added where possible.
The IDNR is currently creating and implementing systems for reporting potential and actual environmental and health impacts. Because these reporting requirements are not yet in place there is no information available on known environmental and health impacts in Illinois.
As with any type of energy extraction, there are several areas of risk when it comes to air quality. In the case of fracking, these risks include air pollutants such as volatile organic compounds (VOCs) and methane. Some environmental groups have raised concerns that methane could be leaked during the extraction process, resulting in unnecessary pollution. Most of this pollution occurs during the well completion phase. Fracking operations can also emit known carcinogens, which have been linked with increased rates of cancer.
With regard to carbon dioxide, when natural gas is used to generate electricity in power plants, it produces fewer carbon emissions than coal-fired power plants. According to a 2014 study by the National Oceanic and Atmospheric Administration, "as a result of the increased use of natural gas, CO2 emissions from U.S. fossil-fuel power plants were 23% lower in 2012 than they would have been” without the increase in natural gas use. During the extraction process, however, methane is emitted, and methane actually traps 20 times more carbon dioxide than other greenhouse gases. Nevertheless, according to the International Energy Agency (IEA), CO2 emissions in the United States dropped by 3.8 percent in 2012, due in large part to the "increased availability of natural gas, linked to the shale gas revolution."
A 2014 report from the U.S. Environmental Protection Agency found a decrease of 3.3 percent in overall greenhouse gas emissions and a 12 percent decrease in methane emissions from 2011 to 2012. Natural gas extraction is the second largest producer of methane, after cattle.
The central and eastern United States have been experiencing an increased number of earthquakes over the last few years, according to the U.S. Geological Survey (USGS), the government agency responsible for such data. Studies from the USGS have not found fracking directly responsible for this increase in felt earthquakes; however, the USGS is looking into regulations that would use seismic data to determine thresholds dictating when and where fracking can occur. There is a growing body of evidence suggesting that this growth in the number of earthquakes has been caused by the increased use of injection wells to dispose of fracking wastewater. While fracking has been rarely known to cause earthquakes, there is an established scientific link between earthquakes and the disposal of fluids in deep, underground injection wells. Once a well has been fracked, the water returned to the surface is called wastewater, and contains large amounts of salt and other contaminants. Some of this water can be recycled, but that water which can't be recycled is often stored in injection wells. These injection wells are generally considered the safest and most cost-effective place for wastewater to be stored. Injection wells are located thousands of feet underground and are encased in cement. Multiple drilling wells often rely on one disposal well for wastewater storage. The U.S. Environmental Protection Agency estimates there are 144,000 of these wells across the United States receiving 2 billion gallons of frack fluid per day.
Induced seismology, or man-made earthquakes, have been around for decades and can be caused by mining, damming rivers and injecting fluids into underground wells. Earthquakes are caused by injection wells when water pumped into underground wells causes the faults under the earth to slip. Even though scientists at the USGS have been able to cause earthquakes intentionally by carefully injecting liquid into the earth, the link between injection wells and earthquakes is not fully understood. One of the largest concerns for scientists and regulators is that they do not have the tools to predict whether wastewater will cause seismic activity. These concerns are compounded by the lack of knowledge about where faults are located across the central and eastern United States. The USGS is just beginning to map these areas in more detail in order to understand the seismic risks. As of June 2014, these earthquakes have typically been small, two or three in magnitude on the Richter scale, but at least one scientist has raised concerns that earthquakes could grow in intensity if old injection wells continue to be used for storage.
When it comes to water protection and fracking there are four main areas of risk: the depletion of fresh water sources, spills and leaks of fracking fluid into water, mismanaged produced water and flowback, and stormwater pollution. Stormwater, flowback, produced water and wastewater can be harmful because they contain total dissolved solids and naturally occurring radioactive materials. Because of the recent rapid growth in fracking, there are still many uncertainties about the effects of fracking on water. There are studies that link fracking to groundwater contamination, but they remain controversial. The U.S. Environmental Protection Agency is releasing a report in spring 2015 on the potential impacts of fracking on drinking water, and is working on effective programs for managing these potential risks.
One of the main criticisms of fracking is that the process uses a disproportionately large amount of water. Up to 10 million gallons of fresh water may be required to frack one well. A 2014 study from the Bureau of Economic Geology at the University of Texas found, however, that the amount of water used in a traditional well, versus a hydraulically fractured well, is not appreciably different. According to one of the researchers, Dr. Bridget Scanlon, "The water used to produce oil using hydraulic fracturing is similar to the water used in the U.S. to produce oil using conventional techniques." The only difference between the amount of water used during the two oil or gas production techniques, is when in the process water is used. The study was funded by the Alfred P. Sloan Foundation.
Any fracking in Illinois may not use this much water however. Because of the shallow shale rocks in the state most oil and gas extraction companies are expected to use gels or other fluids during fracking.
Because of the recent, rapid growth of fracking, little is known about the potential impacts to human health. Government agencies dealing with human health issues have raised concerns about some chemicals that can be released during the fracking process, including VOCs. The Centers for Disease Control are working with the EPA and federal, state and local agencies to better understand potential impacts.
Fracking can also present challenges to communities. Increased oil and natural gas production happens in boom or bust cycles, and often these cycles disproportionately occur in rural communities. Large scale fracking booms can also lead to increases in crime, such as substance abuse, sex trade and domestic abuse. An influx of oil and gas workers also strains housing and traffic resources. This lack of housing can push oil and gas workers into so-called 'man camps,' which are "clusters of mobile homes, RVs, and trucks," or into hotels. A fracking boom also puts heavy traffic on roads, which can strain infrastructure, increase traffic accidents, and increase the likelihood of oil spills. Local governments respond by hiring more police, social workers, health care workers and emergency response personnel, thereby spending more of their budgets on roads and social programs. Currently, much of the tax revenue generated by the oil and gas industry goes to the federal and state government, not the local governments.
Departments, agencies and organizations
- The Illinois Department of Natural Resources (IDNR) is responsible for managing Illinois' natural, cultural and recreational resources for current and future generations and educating the public about these resources. Marc Miller is the current Director of the IDNR. The IDNR is the main responsible party for enforcing the 2013 Hydraulic Fracturing Regulatory Act. The IDNR also oversees 12 offices, complexes or museums.
- The Office of Oil and Gas Resource Management regulates all permitting, drilling, operating and reclamation of oil and gas wells in Illinois. This office is also responsible for enforcing the Illinois Oil and Gas Act. Through these responsibilities the office oversees the cleanup of abandoned well sites, which are funded by the Landowner Grant Program, and the regulation of fluids that are injected under the ground through the UIC program.
- The Office of Mines and Minerals is another office under IDNR. This office is responsible for the state Abandoned Mines Land Reclamation program. It also oversees oil and gas permitting, mine safety and mine blasting.
- The Illinois State Geological Survey (ISGS) provides information on the environment, public safety and the economic vitality of the state. The ISGS is part of the Prairie Research Institute at the University of Illinois Urbana-Champaign.
- The Illinois State Water Survey (ISWS) is responsible for researching and disseminating information about water, the effects citizen's quality of life, environment and economic development. The ISWS is part of the Prairie Research Institute at the University of Illinois Urbana-Champaign.
- The Office of the Illinois State Fire Marshal is responsible for ensuring compliance with state laws regarding storage tanks, pressure valves and fire protection systems.
Laws and regulations
In 2013 Illinois passed the Hydraulic Fracturing Regulatory Act, called the most strict fracking regulation in the nation. This law gives the state much of the responsibility for overseeing fracking, although it does designate some approval authority to local municipalities.
- See also: "Illinois Hydraulic Fracturing Regulatory Act"
- The Illinois Hydraulic Fracturing Regulatory Act (2013) designates the IDNR as the department responsible for granting permits to use hydraulic fracturing or fracking to extract oil and gas. This law sets standards for most aspects of well site preparation, well drilling, hydraulic fracturing and reclamation. It also sets up permitting and reporting requirements, water, air, health and other environmental protections, water quality testing provisions, legislative oversight, taxes and criminal and civil penalties for violations of the law.
See bill: Illinois General Assembly Illinois Hydraulic Fracturing Regulatory Act
- The Illinois Environmental Protection Act creates state-wide rules to minimize environmental damage and encourages local governments to do likewise. This law assigns much of this responsibility to the IDNR and the Department of Commerce and Economic Opportunity and agencies under their direction. This act creates rules and permitting systems designed to prevent or limit air, water, noise, hazardous waste and atomic radiation pollution. The act also establishes procedures for toxic chemical and spill reporting and creates a “Right-to-Know” program. This law creates rules regarding coal combustion by-product and waste. It finds air pollution to be "a menace to public health," limits certain activities to limit air pollution and creates an air pollution permit system. This law also creates Renewable Portfolio Standards (see Energy Policy in Illinois for more information).
See bill: Illinois General Assembly Illinois Environmental Protection Act
- The Illinois Oil and Gas Act creates an Oil and Gas Board to advise the Director of the IDNR on regulation affecting the industry. This act gives the IDNR authority to write rules to prevent blowouts, regulate directional wells, the deepening of wells, the plugging of wells and collect annual well fees. This law also creates rules regarding oil and gas rights leasing and lease sales. This act also creates a permitting system for Underground Injection Wells, liquid oil field waste transportation systems and the Underground Resources Conservation Enforcement Fund.
See bill: Illinois General Assembly Illinois Oil and Gas Act
- On March 18, 2014, citizens in Johnson County voted against a ban on fracking in that county.
Major companies and affected industries
- Strata-X Energy Ltd. has two horizontal drilling permits from the IDNR. This permit is for a well in Clay County. The company has leased oil and gas exploration rights across 49,200 acres in the Illinois Basin.
- The Illinois Oil and Gas Association is a state interest group for oil and gas producers and those leasing land or receiving royalties from oil and gas activities. Organized in 1944 this organization provides information on crude oil prices, oil and gas regulations and has an insurance program.
- The Illinois Petroleum Resources Board was created in 1988 under the Illinois Petroleum Education and Marketing Act. This organization works to educate the public on oil and gas production, promote environmental best practices and support oil and gas research.
- The Southern Illinoisans Against Fracking Our Environment is SAFE is responsible for the Johnson County fracking referendum. SAFE's mission is to ban fracking until this method of extracting oil and gas presents no risks to the environment.
The following table shows the energy types that are used to heat homes in Illinois. Natural gas makes up almost 50 percent of home heating in that state followed by electricity, fuel, LPG, and other. Because of the way that utilities are regulated consumers shouldn't expect to see lower natural gas prices in their state until regulators go through their next ratemaking cycle.
