Last May, MDN brought you the news that the Ohio Department of Natural Resources (ODNR) was laying the blame for a series of low-level earthquakes in southeastern Ohio on fracking at a shale well in Noble County (see ODNR Says Fracking in Noble County, OH Caused Series of Earthquakes). We were somewhat incredulous. Most of the time, low-level quakes are tied to injection wells near active faults, not to fracked shale wells. The enviro-left is making the most of it, ginning up angst in and around Noble County, tying fracked shale wells (not injection wells) to a series of low-level quakes in the region.

Just coming to light now, more than a month after it happened, the Pennsylvania Department of Environmental Protection (DEP) is investigating whether there is any connection between a low-level earthquake (“seismic event”) near Murrysville in Westmoreland County, PA, and the Penneco Environmental Solutions LLC Sedat 3A injection well in Plum Borough in Allegheny County. Operators of injection wells in PA are (usually) required to maintain on-site seismometers. On Feb. 7, the seismometer at the Penneco Sedat 3A site registered a “seismic event” about six miles away near Murrysville. Read More “Low-Level Earthquake 6 Miles from Plum Boro Injection Well”
A few weeks ago, MDN brought you the news that the Ohio Department of Natural Resources (ODNR) is laying the blame for a series of low-level earthquakes in southeastern Ohio on fracking at an Encino Energy shale well in Noble County (see ODNR Says Fracking in Noble County, OH Caused Series of Earthquakes). We were somewhat incredulous. We can count on one hand the number of verified instances when fracking itself (not injection wells) has caused earthquake activity. Yet it appears to be so in this instance, with all future fracking at this site blocked (see Fracking Halted at Encino Pad in Ohio Linked to Earthquakes). The ODNR is now saying, “Any future permits to drill a well that may be issued in the area of this seismicity will include seismic monitoring terms and conditions.” Read More “New Permits Near OH Earthquake Site Require Seismic Monitoring”
Yesterday, MDN brought you the news that the Ohio Department of Natural Resources (ODNR) is laying the blame for a series of low-level earthquakes in southeastern Ohio on fracking at a shale well in Noble County (see ODNR Says Fracking in Noble County, OH Caused Series of Earthquakes). We were/are somewhat incredulous. Most of the time, low-level quakes are tied to injection wells near active faults, not to wells being fracked. However, a new news report says ODNR has halted fracking at the suspect well while it investigates. Read More “Fracking Halted at Encino Pad in Ohio Linked to Earthquakes”
A series of earthquakes (low level, sometimes felt, most of the time not felt) have hit Guernsey and Noble counties in eastern Ohio. According to the latest news we can find, some five quakes have hit since April 22, and another couple of quakes hit earlier in the year, in January/February. There is an existing fault line in the area, near Cambridge, known as the Burning Springs-Cambridge fault zone, formed more than 4.6 million years ago. So, earthquakes in the region are not unknown. The question is, why this most recent flurry? The Ohio Department of Natural Resources (ODNR) claims it’s tied to oil and gas activity in the area.

If we’ve heard it once, we’ve heard it a thousand times–the claim that fracking causes earthquakes. We’ve talked about this issue almost from the beginning of writing the MDN blog site in 2009. A quick summary of our own observations is that frack wastewater disposed of via injection wells (not fracking itself) is the culprit in causing low-grade earthquakes in some areas. However, the wastewater doesn’t cause an earthquake unless the injection well is located on or near a natural underground fault in the rock layer. Rarely (we can count it on one hand) have we read of fracking itself causing an earthquake. Yet a researcher from Ohio’s University of Miami claims research shows fracking itself can cause an increase in earthquakes.

Do you know how many Marcellus (or Utica) shale wells have been drilled in Pennsylvania since shale drilling began? We’re talking drilled, fracked and now online. That number is now over 9,000. You know how many times fracking has caused an earthquake (or “seismic event” as it’s called in the biz)? Precisely once. Which is statistically zero. The Pennsylvania State Seismic Network (PASEIS) keeps track of these things, and that’s what they say. One fracking-induced “event” that happened back in April 2016.

American Water Management Services (AWMS) owns a wastewater injection well in Trumbull County that supposedly caused a low-level earthquake (that nobody could feel) in 2014. Two wells located at the site, both operated by AWMS, were “temporarily” shut down by the Ohio Dept. of Natural Resources following the quake (see ODNR Temporarily Shuts Down Injection Wells After Low-Level Quake). AWMS appealed the closure of the wells all the way to the Ohio Supreme Court. ODNR is still trying to block one of the two wells from opening by saying AWMS *could* open the well–if they submit an acceptable (comprehensive) plan.

Yet another “fracking may cause earthquakes” study has been published in the so-called peer reviewed journal PNAS (Proceedings of the National Academy of Sciences). Researchers from the University of Miami (in Ohio) admit the kind of earthquakes they talk about in their paper, potentially caused by Utica Shale drilling, are “rare.” But, they are also “concerning.” Yes, everyone should be concerned that in zero percent of Utica well drilling cases (statistically speaking) there have been NO earthquakes. Actually a couple of cases are thought to be related to fracking over a fault–but it’s still unproven. Statistically speaking, it’s 0%. But, there could be problems! Maybe. If the conditions are “just right.” Ya never know. We note the researchers didn’t address concerns over fans in football stadiums that, when they all stomp their feet at the same time, have caused “earthquakes” that are higher on the Richter scale than the ones they postulate “may, maybe, might” happen in Utica drilling. No mention of football fan earthquakes in this study. Below is the “news” about this latest, breathlessly urgent report that everyone should read… Read More “Yet Another Fracking-Causes-Earthquakes “Study” – This Time in Utica”
Yes, we must revisit the topic of “fracking causes earthquakes” yet again (sigh). But maybe this time something good will come of our discussion. Researchers at Stanford University (crazy California) have discovered a way to detect thousands of faint, “previously missed earthquakes” triggered by fracking and by injection wells. “The technique can be used to monitor seismic activities at fracking operations to help reduce the likelihood of bigger, potentially damaging earthquakes from occurring,” according to a published research study. By now you know our standard explanation, the facts about fracking and earthquakes: (1) Injection wells can and do cause detectable earthquakes–when they are located over faults. (2) Fracking shale wells rarely causes detectable earthquakes. We know of perhaps a half dozen times when fracking a well, which again happened to be over a fault, caused an earthquake. Out of the millions of fracked wells that have been drilled. Statistically speaking–fracking doesn’t cause earthquakes–detectable earthquakes, that is. You have to understand something about earthquakes and fracking. From the Standord researchers: “Earthquakes generated by fracking are typically no larger than magnitude 0. That’s equivalent to the amount of energy released when a milk carton hits the floor after falling off a counter.” However, every now and again an earthquake will hit a 1 or even 2 magnitude. Above 2 is barely noticeable by humans. What the Stanford researchers have done is to figure out how to monitor seismicity when fracking (or injecting wastewater into wells), and use that information to predict when the activity may lead to triggering a larger quake. Now that is useful information… Read More “Stanford Researchers Now Able to Detect “Earthquakes” from Fracking”
Broadband seismometer used for surface seismic monitoring
We hesitated to use the headline that we did, given the way virulent anti-drillers bastardize the issue of fracking and earthquakes. But we used it to make a point. Quick history: The headline-grabbing “fracking causes swarms of earthquakes” in places like Oklahoma is about frack wastewater that is injected in special saltwater injection wells, deep below the surface. There are, literally, hundreds of thousands of such wells across the country. Unfortunately, when such a well is located directly over or very close to an underground fault (large crack), the fluid getting injected acts like grease, allowing rock layers to slip and slide–in some cases causing low level earthquakes–typically earthquakes under 2.0 on the Richter scale (can’t be felt on the surface). Is fracking itself ever the cause? Statistically, no. But it has been documented to happen in a handful of cases–under 10 times in the entire world, out of millions of fracked wells. And again, it only happened because of fracking directly over an underground fault. However, any time you explode charges underground, which is what fracking is, if you have equipment sensitive enough, you can detect it. Is that an “earthquake”? We’d say no. Perhaps it is considered an “earthquake” according to a technical definition, but those extremely low vibrations are brief–typically 30-60 seconds–and they never cause any kind of harm on the surface. In fact, the vibrations can’t be felt at the surface. So our headline referring to “tiny earthquakes” is somewhat tongue-in-cheek, a way to tweak antis. Researchers at the National Energy Technology Laboratory (NETL) have discovered that those vibrations from fracking–what they call “low frequency tremors”–can be measured and used to figure out how to get more production out of Marcellus Shale wells in PA and WV… Read More “NETL Researchers Find Tiny Earthquakes Help Marcellus Production”
In late December 2011 a 4.0 earthquake hit the Youngstown, OH area. It was the latest in a string of quakes that began in March 2011, shortly after a wasterwater injection well went online–the Northstar #1 well. In March 2012 the Ohio Dept. of Natural Resources (ODNR) made a determination that indeed, it was the Northstar well that caused the quake–due to its location over an active fault (see ODNR Finds Youngstown Injection Well Caused Earthquakes). When you force liquid of any kind deep into the ground and into a fault (gigantic crack running through the rock layers), that liquid acts like grease allowing the rock layers to slip and slide, causing an earthquake. It’s a rare occurrence, at least in Ohio. Without recounting the entire sordid story, ownership of Northstar #1–originally owned by D&L Energy, whose owner was found guilty of illegal wastewater dumping unrelated to the injection well–the current owner has filed an application to permanently, and for all time, plug and close Northstar #1… Read More “OH Injection Well that Caused OH Earthquakes Shutting Down Forever”
Early Sunday morning there was a low-level earthquake in Monroe County, OH–that literally nobody felt–but was picked up on seismic monitors by the U.S. Geological Survey. There was, according to the Ohio Dept. of Natural Resources (ODNR) one fracking operation “near” the earthquake that ODNR shut down within an hour after the event–out of an abundance of caution. Immediately several radical anti-drilling groups, including the Ohio Environmental Council and the Sierra Club, jumped on the news and declared fracking unsafe and too risky in the nearby Wayne National Forest. With zero proof that it was tied to either fracking or wastewater injection wells. Here’s the news, and the way the news is being distorted by antis… Read More “Overraction by Antis to Unfelt Earthquake in Monroe County, OH”
On Friday, the Pennsylvania Dept. of Environmental Protection held a hastily-called webinar to discuss findings that, frankly, aren’t all that newsworthy or surprising. After 10 months of study, the DEP has concluded that zipper fracking activities by Hilcorp in Lawrence County, PA “likely” caused a series of earthquakes in April 2016 so minor that nobody could feel them. And the DEP concluded this after 10 months of study, when a week before the DEP itself issued the permits to drill in Lawrence County, Hilcorp drilling was shut down about seven miles away, across the border in Mahoning County, Ohio, for potentially causing low-level earthquakes there (see Hilcorp Awarded Permits to Drill 7 New Wells Near Earthquake Zone). It wasn’t exactly rocket science to connect the dots and speculate that fracking over top an active fault had caused the low-level earthquakes on the PA side of the border, as it had on the OH side of the border. As we’ve stressed multiple times here on MDN, earthquakes related to shale are almost always connected with injection wells–when large amounts of liquid are injected near a fault. Earthquakes from fracking activities are rare–like under 10 times, ever, out of millions of fracked wells. Statistically zero. Still, let’s not let a good “crisis” go to waste. The DEP, in releasing a report about the incident (full copy below), said they will work up new regulations to detect and prevent such statistically zero occurrences from happening again… Read More “DEP Says Fracking at PA Utica Wells “Likely” Caused Earthquakes”
In April of last year (2016), MDN brought you the story of earthquakes so minor nobody could feel them in Lawrence County, PA were likely caused by fracking (see PA DEP Investigates Hilcorp Fracking in Earthquake Nobody Felt). However, seismic monitoring equipment could detect them. We have to stress that earthquakes caused by fracking is rare–like this is one of five instances we’re aware of. Far more common are earthquakes caused by deep injection wells. But fracking itself? Statistically zero percent of the time earthquakes are caused by fracking. So when it happens, it’s noteworthy. The conditions must be just right–fracking immediately overtop a fault in the rock layers. The driller in this case, Hilcorp, was ordered to stop all fracking and drilling activity at the well site, which they did. The Pennsylvania Dept. of Environmental Protection (DEP) says they have concluded their investigation and will today (on a webinar) disclose their results. Here’s the kicker: the DEP could have avoided this. Two years earlier the same driller, Hilcorp, caused minor earthquakes seven miles away–just across the border in Ohio. At that time Ohio officials stopped Hilcorp from drilling in that region. A week after the Ohio earthquakes that stopped Hilcorp, the PA DEP issued permits to drill in the same area (see Hilcorp Awarded Permits to Drill 7 New Wells Near Earthquake Zone). MDN was the only source to make that observation. We waved our little red flag and said maybe it’s not such a wise decision to grant those permits. Someone at the DEP needs to read MDN! At any rate, below is the news, as much of it as we currently know. By the time you read this, the DEP earthquake webinar will be over, but we’ve included the webinar notice as (so far) it’s the only information we have to indicate the DEP now concludes Hilcorp drilling was at fault for the earthquakes in Lawrence County… Read More “DEP Concludes Hilcorp Drilling Caused Minor Earthquakes in W PA”
On Dec. 31, 2011, the Youngstown, OH area experienced a 4.0 earthquake that was later determined to be caused by a wastewater injection well (see Youngstown Earthquake and Fracking: Is There a Connection? and ODNR Finds Youngstown Injection Well Caused Earthquakes). The Ohio Dept. of Natural Resources (ODNR) later enacted new regulations to prevent future occurrences of earthquakes from either injection wells or fracking itself (see Did ODNR Overreact & Set Earthquake Detect Bar Too Low?). As we pointed out in 2014, the new rules would have shut down the Cleveland Browns stadium–if all of the fans were to begin stomping their feet it would create an “earthquake” greater than the allowed limits set by ODNR. Since the new rules were enacted there have continued to be earthquakes in Ohio, but not “felt” earthquakes from injection wells (see Study Says Series of Unfelt Earthquakes in OH from Utica Fracking). Typically an earthquake must reach 2.5 on the Richter scale to be felt on the surface. Since spring of 2012, there have been no major (above 2.5) earthquakes in Ohio related to injection wells, although there have been a few felt earthquakes supposedly tied to fracking over an active fault (see OH Researchers Confirm Hilcorp Fracking Caused Low-Level Quakes). Now five years later, the ODNR is patting itself on the back, taking credit for the reduced number of earthquakes tied to injection wells, because (they say) of their super-restrictive regulations… Read More “ODNR Says No ‘Felt’ Earthquakes from Injection Wells Last 5 Yrs”
