Oklahoma Ignores Link Between Record Number of Earthquakes and Fracking Wastewater Disposal Wells

Oklahoma fracking earthquakes

As Oklahoma continues to experience more earthquakes than California this year, residents are questioning why regulators haven’t taken any meaningful action to guard against increased seismic activity.

The U.S. Geological Survey (USGS) says that wastewater injection into deep geologic formations, a part of the hydraulic fracturing (fracking) process, is a likely contributing factor to this increase in quakes. The phenomenon, known as “injection-induced seismicity,” has been documented for nearly half a century, according to the USGS.

The rate of earthquakes in Oklahoma has increased remarkably since October 2013 — by about 50 per cent — significantly increasing the chance for a damaging magnitude 5.5 or greater quake in central Oklahoma,” says the USGS report.

Angela Spotts is one of many Oklahoma residents who is wondering why no meaningful action has been taken to safeguard residents.

It is kind of like an assault. You feel like you are being sacrificed for this gold they are pulling out of the ground. And you start meeting people that are getting sick,” Spotts, a member of Stop Fracking Payne County, told DeSmogBlog. “It is the tobacco industry all over again.”

Texas Regulators Sidestep Connection Between Fracking Industry and Earthquakes

New rules for Texas injection wastewater well operators offer no relief to people impacted by more than 30 earthquakes that hit Azle, Reno and Springtown almost a year ago. Many buildings in the three small cities, 50 miles west of Dallas, Texas, suffered broken windows, cracked walls, damaged plumbing and foundations. 

Seismic activity is not something the region is known for. It was only after deep injection disposal wells used to house fracking's toxic wastewater went into operation that the earthquakes started. There are several injection wells in the area — three of which some suspect to be the cause of the quakes due to their proximity to impacted neighborhoods and the volume of disposal operations.

“Injection raises the underground pressure and can effectively lubricate fault lines, weakening them and causing earthquakes, according to the U.S Geological Survey,” reports McClatchy Washington Bureau

The Texas Railroad Commission, the agency that regulates the oil and gas industry, was met with public outcry after the first earthquake swarm. The commissioners acted fast (by the agency’s standards), coming up with new rules to address the situation released on Oct. 28.  

The new rules require oil and gas companies to check local seismic data from the U.S. Geological Survey before opening a new waste disposal well. They also give the agency the power to change, suspend or revoke an injection operator’s permit if the commission determines the well is contributing to seismic activity.

Second Earthquake in Under a Month Shuts Down Colorado Fracking Wastewater Injection Well

second earthquake struck Greeley in northeastern Colorado on Monday, June 23 prompting the state's Oil and Gas Conservation Commission to order a halt to the injection of contaminated drilling wastewater into a deep disposal well in the area.

The ban on injecting wastewater will last for 20 days as officials explore a potential link between the injection activity and the sudden jump in seismicity in the area. The most recent quake was a 2.6 magnitude temblor that hit about five miles north of Greeley at 12:27 p.m. It follows a 3.4 magnitude quake which struck the same area May 30.

Two quakes in less than a month, in an area the U.S. Geological Survey formerly called “aseismic,” has led to speculation that the temblors are “frackquakes,” seismic activity induced by the injection of drilling wastewater into deep rock formations.

Frackquakes in Colorado? Scientists Probe Fracking Wastewater Link to CO Earthquakes

At 9:35 p.m. on Saturday, May 30, Greeley, Colorado was struck by a 3.4 magnitude earthquake. Earthquakes are highly unusual in eastern Colorado, raising speculation that it was a “frackquake” — a man-made earthquake stimulated by the disposal of contaminated drilling water in deep injection wells. This disposal technique forces wastewater generated from hydraulic fracturing (fracking) deep into underground rock formations, lubricating layers of rock that would not ordinarily be subject to movement.

Earthquakes are so rare in eastern Colorado that the U.S. Geological Survey (USGS) has labeled the area “aseismic.” The Greeley Tribune reported that the May 30 quake's epicenter was roughly two miles away from two deep oil and gas wastewater injection sites that have not been inspected for two years.

Scientists placed seismometers around the area to try to gather more detailed information on what may have generated the quake and its aftershocks. Colorado currently has very few seismometers in place because earthquakes are so rare in the state.

Shale Rush Hits Argentina as Oil Majors Spend Billions on Fracking in Andes Region

While many countries, including France, Germany and South Africa, have banned or delayed their embrace of fracking, one country is taking a full-steam-ahead approach to the unconventional drilling technology: Argentina.

The country is welcoming foreign shale companies with open arms in the hope that oil and gas drilling will help combat one of the world’s highest currency inflation rates. But the government there is also facing violent clashes over fracking in arid regions of the Andes mountains and allegations from locals of water contamination and health problems.

Argentina’s Vaca Muerta shale formation — estimated to hold an amount of oil and gas nearly equal to the reserves of the world’s largest oil company, Exxon Mobil — has already attracted billions in investment from the major oil and gas company Chevron.

In April, the government drew global attention when it announced plans to auction off more acreage. “Chevron, Exxon, Shell have shown interest in Vaca Muerta. They will compete for sure,” Neuquen province Energy Minister Guillermo Coco told potential investors on a road show in Houston on April 30th.

Argentina, which the EIA estimates could hold even more shale gas than the U.S., already has over 150 shale wells in production, more than any country in the world aside from the U.S. and China. California-based Chevron, in partnership with Argentina’s state-owned oil company YPF, invested $1.24 billion in a pilot program last year. Last month, Chevron announced an additional $1.6 billion effort for 2014, part of Chevron's overall investment plan that could top $15 billion. The company is hoping that this plan will allow it to extract 50,000 barrels a day of shale oil plus 100 million cubic feet of shale gas per day from the country’s Andes mountain region.

American drillers have talked up Argentine shale as the next big thing. “Vaca Muerta is going to be an elephant compared to Eagle Ford,” Mark Papa, CEO of EOG Resources told the Argentine press in 2012, referring to a major oil-producing shale formation in Texas.

Ohio Geologists Link Earthquakes to Fracking, State Introduces Seismic Monitoring

The Ohio Department of Natural Resources announced earlier this month that it will start requiring oil and gas companies to install networks of sensitive seismic monitors on their wells to detect small earthquakes that could be caused by hydraulic fracturing, or “fracking.” 

The special requirement will kick in if companies request permits to drill horizontal wells within three miles of known fault lines, or where earthquakes greater than a 2.0 magnitude have already been recorded. If the monitors detect any tremors in excess of 1.0 magnitude, drilling must cease while experts investigate the cause of the seismic activity. 

The new rules are the department's response to recent earthquakes in Ohio's Poland Township in Mahoning County — which Rick Simmers, chief of the Ohio Department of Natural Resource's oil and gas division, says have a “probable connection” to hydraulic fracturing activity in the area.

The March earthquakes mark the first time state geologists in Ohio have definitively linked earthquakes to gas drilling. They believe that fracking for gas in the Utica Shale beneath the Appalachian mountains caused five earthquakes in the area by increasing pressure on a previously unknown fault. 

Ohio has also imposed an indefinite moratorium on new drilling in the area of the earthquakes, but will allow extraction to continue at five other existing wells at the site.

Earthquakes Rattle Texas Towns in the Barnett Shale

Daniel Hogan thought he heard a sonic boom when a magnitude 3.6 earthquake hit Azle, Texas, last November. His home sustained damage — broken windows, cracked walls, damaged plumbing and foundation — but he did not have earthquake insurance to cover the repairs. He never imagined he'd need such protection in Texas.

Daniel Hogan reads a song he wrote about the earthquakes: 

Since November, Azle, Reno and Springtown, three small cities 50 miles west of Dallas, have been at the epicenter of more than 30 earthquakes. The seismic activity began after deep injection disposal wells built to house fracking's toxic wastewater went into operation. There are several injection wells in the area — three of which some suspect to be the cause of the quakes.

Could California's Shale Oil Boom Be Just a Mirage?

Since the shale rush took off starting in 2005 in Texas, drillers have sprinted from one state to the next, chasing the promise of cheaper, easier, more productive wells. This land rush was fueled by a wild spike in natural gas prices that helped make shale gas drilling attractive even though the costs of fracking were high.

As the selling price of natural gas sank from its historic highs in 2008, much of the luster wore off entire regions that had initially captivated investors, like Louisiana’s Haynesville shale or Arkansas’s Fayetteville, now in decline.

But unlike natural gas prices, oil prices remain high to this day, and investors and policymakers alike remain dazzled by the heady promise of oil from shale rock. Oil and gas companies have wrung significant amounts of black gold from shale oil plays like Texas’s Eagle Ford and North Dakota’s Bakken.

Shale oil, they say, is the next big thing.

“After years of talking about it, we’re finally poised to control our own energy future,” President Obama said in his most recent State of the Union address. “We produce more oil at home than we have in 15 years.”

But once again, the reality may be nothing like the hype. Consider California.

USGS Study Connects Earthquake Risk To Wastewater Injection, Fracking Advocates Say, "Who Cares?"

A new study out in Science by US Geological Survey scientist William Ellsworth links earthquakes to wastewater injection sites. These earthquakes, thought to be caused by pressure changes due to excess fluid injected deep below the surface, are being dubbed “man-made” earthquakes.

It's not the first time scientists have used that moniker, as earthquakes have been associated with other industrial operations that mess with underground formations such as surface and underground mining or dams that impound water into reservoirs.

Yet, in more recent years, we're seeing more and more of them,

“The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. More than 300 earthquakes above a magnitude 3.0 occurred in the three years from 2010-2012, compared with an average rate of 21 events per year observed from 1967-2000.”
 


Many likely know that “wastewater” is a byproduct of many fossil fuel processes. It can come from raw material itself or is a leftover from purification steps during the extraction and processing phases of fuel production.

Contaminated Water, Land Damage, and Earthquakes: The Legacy of Waste Injection Wells

contaminated water from wastewater injection well

Early scientific analysis predicted that the risks associated with hazardous waste injection wells would be negligible. Unfortunately, experience has indicated that disposing of hazardous waste deep underground has been linked to water contamination, destroyed ecosystems, toxic leaks and earthquakes.

Now we are learning that there is a difference between scientific analysis and scientific evidence.

In a recent extensive report by ProPublica, John Apps, leading geoscientist, who advises the Department of Energy for Lawrence Berkeley National Labs, said that the science used to go forward with disposal wells was not sound.

“Every statement is based on a collection of experts that offer you their opinions. Then you do a scientific analysis of their opinions and get some probability out of it. This is a wonderful way to go when you don't have any evidence one way or another… But it really doesn't mean anything scientifically.”
