In 2010 when I first started writing about hydraulic fracturing — the process of blasting a cocktail of water and chemicals into shale to release trapped hydrocarbons — there were more questions than answers about environmental and public-health threats. That same year Josh Fox's documentary Gasland, which featured tap water bursting into flames, grabbed the public's attention. Suddenly the term fracking — little known outside the oil and gas industry — became common parlance.

A string of small earthquakes were reported the town of Blackpool just days after fracking operations restarted in England after a seven year hiatus, raising concerns that the controversial drilling process could eventually trigger bigger temblors.
It would appear that the resurgence of fracking in the UK is on very shaky ground. A company called Cuadrilla restarted the controversial technique at a site in Lancashire, in Northwest England, just two months ago after a seven year hiatus. But it spent a month of that time doing tests with smaller volumes of water after a series of small earthquakes in October, The Guardian reported.
The return of fracking to the UK is off to a truly shaky start.
Cuadrilla Resources, the company fracking two wells at the Preston New Road site in Lancashire in northwest England, confirmed Tuesday they had paused operations for the day after a tremor registered a magnitude of 0.4. Tuesday's tremor was only the largest of six that have been detected near the site since Cuadrilla began fracking again, The British Geological Survey said.
In part of his ruling, Mr. Justice Dove found that the government had not taken up-to-date information on climate change into account when drafting its policy. This could make it easier for campaigners to challenge new fracking sites in the future on the basis of their climate impacts, The Guardian explained.

Earthquakes in the central and eastern U.S. have increased dramatically in the last decade as a result of human activities. Enhanced oil recovery techniques, including dewatering and hydraulic fracturing, or fracking, have made accessible large quantities of oil and gas previously trapped underground, but often result in a glut of contaminated wastewater as a byproduct.
The 5.5-magnitude temblor that struck the city of Pohang on Nov. 15, 2017 was the second most powerful on record and its most damaging, leaving the infrastructure in ruins, injuring dozens of people and leaving about 1,500 homeless.

In January 2015 North Dakota experienced one of the worst environmental disasters in its history: A pipeline burst, spilling nearly 3 million gallons of briny, saltwater waste from nearby oil-drilling operations into two creek beds. The wastewater, which flowed all the way to the Missouri River, contained chloride concentrations high enough to kill any wildlife that encountered it.
Environmental activists were sentenced to prison Wednesday for their anti-fracking demonstrations in northwest England.
Roscoe Blevins, 26, and Richard Roberts, 36, were given 16 months in prison. Richard Loizou, 31, was given 15 months. The three were found guilty of public nuisance offense by a jury in August, The Guardian reported. A fourth protester, Julian Brock, 47, received a 12-month suspended custodial sentence. He pleaded guilty for the same offense at a separate hearing.

Two 4.2-magnitude earthquakes struck near Enid in northern Oklahoma Sunday at 5:17 p.m and 9:40 p.m., according to the U.S. Geological Survey (USGS). They are the largest recorded this year so far and even felt in neighboring Kansas.
The large quakes were followed by two smaller ones around the same area early Monday. The first was a magnitude 2.7 followed by 12:35 a.m. then magnitude 2.6 at 6:16 a.m.
The alarming string of earthquakes that have shaken Oklahoma for years has long been tied to the large volume of fracking wastewater dumped into the state's injection wells. And while state regulators have taken numerous measures to reduce wastewater disposal volumes to prevent such "induced" earthquakes, they might want to consider another measure—restricting how deep wastewater gets sent underground.
A new study, published Thursday in the journal Science, finds that Oklahoma's earthquakes can also be triggered by wastewater injection depth.

Four years ago, the Illinois legislature passed a law to regulate high volume hydraulic fracturing, or fracking, after months of contentious negotiations between oil industry interests, environmental watchdogs and community groups.
Leading up to the law's passage, companies had secured hundreds of leases to potentially frack in Southern Illinois.

President Trump and Interior Sec. Ryan Zinke are continuing their onslaught against American public lands this holiday month and moving forward with plans to auction off 700,000 acres for fracking, endangering clean air and water, the climate and sacred lands.
"First it's our cherished national monuments, now Trump and Zinke are set to give away even more public lands to the fossil fuel industry," said Becca Fischer, climate guardian for WildEarth Guardians. "Rather than giving back this holiday season, this administration is proving that it will stop at nothing to put our public lands in the hands of dirty energy executives and sell off our rights to clean energy and a healthy environment."
Earthquakes in Pennsylvania are usually rare but fracking operations triggered a series of small temblors in Lawrence County last year, officials at the state's Department of Environmental Protection (DEP) announced in a Feb. 17 report.
Hilcorp Energy Co., a Texas-based oil and gas company, was fracking a pair of wells in the Utica Shale when seismic monitors detected five earthquakes measuring between 1.8 and 2.3 on the Richter scale between April 25-26, 2016.
"Our analysis after doing the review... is that these events are correlated with the activity of the operator," DEP Acting Secretary Patrick McDonnell told Penn Live.
While the tremors were too small to be felt by humans or cause any damage, they are the first quakes in the state to be blamed on fracking. Pennsylvania happens to be the second largest natural gas-producing state in the country.
"At least within Pennsylvania, this is the first time that we have seen that sort of spatial and temporal correlation with [oil and gas] operator activity," Seth Pelepko, chief of well-plugging and subsurface activities for DEP's oil and gas management program, told Allegheny Front, a western Pennsylvania public radio program.
"No faults identified along portions of the well bore where these seismic events were detected," Pelepko continued.
Hilcorp spokesman Justin Furnace said operations were immediately suspended after learning about the tremors. Fracking and stimulation operations have since been discontinued at the well pad indefinitely.
The DEP said that Hilcorp was using a technique known as "zipper fracturing" at the time, which involves the concurrent fracking of two horizontal wellbores that are parallel and adjacent to each other.
So how did the earthquakes happen? As Penn Live explains:
Four wells were drilled to depth of about 7,900 feet in that location.
Evidence indicates that induced earthquakes occur when the separation between Utica Shale and basement rocks is lessened during drilling operations. That means, when someone drills too close to basement rocks, there can be earthquakes.
Pelepko said that seems to have been the case in Lawrence County, where the basement rock is shallow compared to other areas in the state.
The distance between Utica Shale and basement rocks were between 2,500 to 3,000 feet at the fracking site.
The DEP has since given a number of recommendations to Hilcorp, including the discontinuation of zipper fracturing near gas wells in North Beaver, Union and Mahoning Townships where the earthquakes occurred. Additionally, the company must shut down operations and notify the DEP should any earthquake larger than 2.0 or three successive quakes between 1.5 and 1.9 in magnitude occur within a three-mile distance of a wellbore path.
Earthquakes caused by fracking a well are uncommon. However, the notorious spate of earthquakes in Oklahoma, which were caused by the disposal of large quantities of fracking wastewater into underground wells, are rampant. The disposal of wastewater produced from fracking, has led to the alarming increase of earthquakes with magnitude-3 or larger by nearly 300 times, or 30,000 percent in north-central Oklahoma alone. In 2014, more than 5,000 earthquakes were reported.

U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt recently proposed eliminating federal tax credits for wind and solar power, arguing that they should "stand on their own and compete against coal and natural gas and other sources" as opposed to "being propped up by tax incentives and other types of credits...."
Stand on their own?
Pruitt surely must be aware that fossil fuels have been feasting at the government trough for at least 100 years. Renewables, by comparison, have received support only since the mid-1990s and, until recently, have had to subsist on scraps.
