Frack tracks?

Activists: Mysterious land scars may be caused by oil/gas waste

By Jefferson Dodge

They kind of look like alien-made crop circles, but the jury is still out on whether mysterious linear shapes in Weld County are the work of frackers or ranchers feeding their cattle.

Colorado activists have raised concerns about satellite imagery of what appears to be scarred earth caused by the dumping of oil/gas drilling waste, but state officials maintain that most of the strange patterns are simply areas where livestock feed was deposited.

Shane Davis, chair of the Poudre Canyon Group of the Sierra Club, and Gary Wockner, Colorado program director of Clean Water Action, submitted the aerial photos to Gov. John Hickenlooper on March 5.

In an accompanying letter, Davis and Wockner wrote that the images seem to support rumors that have been circulating about the illegal disposal of drilling and hydraulic fracturing (fracking) fluids and other wastes.

“These images appear to support the rumored allegations and may suggest that drillers and frackers may have been driving tanker trucks off-road, opening the valve on the tanks while driving, and spraying drilling and fracking fluids and wastes across the landscape,” they wrote. “The images suggest that the chemicals sprayed out may have killed the vegetation on the landscape — green areas are turned orange/brown or completely white. Two-track wheel tracks can be seen trailing some of the alleged possible dumping sites.”

Davis and Wockner asked Hickenlooper to direct state officials to investigate, which they did over the following 11 weeks. Davis says the state requested two extensions due to the difficulty of the research involved.

In a May 22 letter, Thomas Kerr, acting director of the Colorado Oil and Gas Conservation Commission (COGCC), dismissed the claims.

According to Kerr’s letter, COGCC staff examined aerial photos and conducted on-site inspections at a “subset” of the locations in question on May 5 and May 10. The state’s investigation appears to focus solely on the Guttersen Ranch, where Kerr said “many” of the wells identified by Davis and Wockner are located.

The Guttersen Ranch is an active cattle ranch that also has numerous oil and gas wells, and the fenced property is strictly monitored to prevent dumping and trash disposal, Kerr wrote. He attributed the strange land scars to two things: the permissible spread of drilling mud and the feeding of cattle.

Kerr acknowledged that “in a few cases, fresh water-based bentonitic drilling mud was land applied to well sites as a beneficial soil amendment,” which is allowed under COGCC rules. Bentonitic mud, which is produced as the drill bores through the earth and sends rock “cuttings” material up the well shaft, “have effectively been used to stabilize areas of blow sand throughout Northeastern Colorado,” Kerr wrote, and “areas where it was applied have been re-seeded and re-vegetation is occurring. The land application of this material only occurs with the consent of the landowner.”


He noted that other byproducts such as oily wastes and fracking “flow-back” fluids “cannot be land applied and require proper handling and disposal” according to state and federal rules.

Kerr said that interviews with one of the landowners indicate that the linear features identified by Davis and Wockner “were likely temporary livestock feeding areas with the ‘orange/brown’ features depicted in the photo likely comprising hay or other livestock feed for 1,000 head of cattle.”

He concluded that “we have not been able to corroborate the allegations. No evidence of illegal dump ing of drilling fluids, drill cuttings, fluids or other wastes was identified.”

But Davis still has his doubts. He notes that the COGCC did not address the aerial photo that features what appears to be gray, delta-shaped flow areas. And since most of the wells in question are operated by Noble Energy, he questions whether the outcome of the state’s investigation was affected by the fact that it was released just as Hickenlooper was joining Noble officials to announce the opening of the company’s new operations center in Greeley and its plans to invest $8 billion in the area over the next five years.

Davis dismisses the idea that the drilling mud is beneficial to croplands, given that it contains radioactive isotopes. He also disputes the notion that the land scars were simply areas where cattle were being fed, and he says he plans to collect soil samples on public lands where the patterns have been made.

A Boulder Weekly examination of satellite images and aerial photos taken of the Guttersen Ranch over time failed to uncover other examples of the patterns found by Davis and Wockner, even though the outline of the shapes that the pair discovered in photos taken in 2006 have remained for years and are still visible today.

The lack of similar lines in other areas of the property during other periods raises several questions. Was that the only time the ranchers fed their cattle in that manner? Why are the lines only found emanating from oil/gas wells? Why aren’t there similar scar patterns elsewhere on the ranch and in other years, assuming the ranch has fed its cattle at other times and locations?

When reached by phone, Guttersen Ranch co-owner Art Guttersen declined to answer questions about their cattle-feeding patterns or processes.

“I’d rather not say anything, just because we don’t want to draw any more publicity to our name or our ranch,” he said. “I thought it was a closed case. If you’re going to do a story on it, it’s just going to open the whole thing back up.”

When advised of Davis’ continuing doubts about the explanation offered for the strange lines, Guttersen said, “I don’t give a shit about the guy, to be honest with you.”

The 12 site reports of the inspections contain virtually identical narratives written by COGCC inspector Jim Precup. Precup writes that he found no cuttings, and that he called Guttersen about the claims. “[Guttersen] said that he had also received a letter from the Sierra Club and was highly offended by the letter. He said I could check all I wanted and that he was willing to open the property to anyone to check for cuttings. He said they would find none. He told me that he had over a thousand head of cattle and what the satellite views represented were feeding stations, nothing more.


“I also called Mr. Ryan Litfin from Noble and asked him if he knew of any drill cuttings being placed on the Guttersen property? He said why would anyone think that they would place cuttings right next to their wells? He also said Noble had their own sights [sic] to dispose of drill cuttings.”

When reached by phone, Precup referred questions to Kerr. When asked about the cattle-feeding explanation — and why the patterns don’t appear in other ranch locations and time periods — Kerr told BW, “because the cattle might not be there at other times, and he might not be feeding them. It’s just a periodic thing. They don’t always hay their cattle, only in certain times when they need to have additional feed that the land’s not providing. And I’m not a rancher, I’m not an expert on it.”

He added that it’s “a matter of circumstance where aerial photos managed to capture it, and then the cows eat it up, so then it disappears. It’s a time-sensitive thing.”

Kerr acknowledged that his staff did not address the fact that the scars lasted for years and seemed to be an isolated case. But he says his staff did take a few soil samples “where the site looked like there was something that was questionable,” and those samples turned up nothing untoward.

Kerr clarified that any bentonitic mud would have been spread on and around the well pad, which is allowed, but it wouldn’t have been dumped in lines. Drill mud that is used for cropland is tilled into the soil with the permission of the landowner and under a permit obtained by the oil/gas operator, he explained, so the patterns identified by Davis and Wockner are being attributed solely to cattle feedings.

When asked about the image showing gray, delta-like flows that Davis says was left out of the investigation, Kerr looked at the photo and acknowledged, “I see the gray spots coming off the pads, and the one that’s circled, it looks like it’s actually running off the pad. I’d have to ask [staff ] what they found on those specific locations.”

When asked whether any of the areas identified by Davis and Wockner were not located on the Guttersen Ranch, Kerr said he didn’t know. Similarly, he couldn’t say why the purported cattle-feeding lines only appear next to oil/gas wells.


“It was difficult for us to figure out what actually happened until we talked to Mr. Guttersen about it,” Kerr said. “It was the best thing we could find, and it took us a while to try to figure out exactly what it was.”

He claims that Davis and Wockner are barking up the wrong tree.

“I understand Mr. Davis and Mr. Wockner’s concerns, I think they have great concerns and it’s good, but I just think they’re trying desperately to find something to use, and I’m just not sure that this is exactly the smoking gun they’re looking for.”

He acknowledged that the COGCC does periodically hear rumors of trucks illegally dumping wastewater, but it’s usually described as being done on streets.

“Typically, when those claims are made, they generally dump it on the road so that it’s hidden,” Kerr said. “In other words, if they dump brine water on a field, it could easily result in salt kill, and so they don’t do that. The accusation is typically that they dump it on the road.”

And it would be foolish to dump illegally on a piece of property where you have hundreds of wells, he adds.

“The last thing you want to do is get caught doing something like that, because the surface owner is going to take action against you,” Kerr said.

Tisha Schuller, president and chief executive officer of the Colorado Oil and Gas Association, showed one of the aerial photos in question at a June 12 Loveland City Council meeting and explained the scars away as the application of beneficial drill cuttings and mud on cropland.

“One of the things companies do is they can use drill cuttings for agricultural purposes,” she told the council.

When Boulder Weekly asked Schuller for further comment, Doug Flanders, COGA director of policy and external affairs, sent the following to BW via email: “While COGA has not seen nor been privy to the follow-up correspondence between the COGCC and the Sierra Club, our understanding is that the Sierra Club’s accusation was unfounded and unrelated to any oil and gas operations.”

That comment by COGA was a joke!


COGA is a joke.


A typical netty pot is a ceramic vessel where you add boiled or distilled water, salt, tea or saline (salt solution) with herbs. You can visit the chemist’s and find neti pot solution available.

Typica Shane Davis/Gary Wockner:  Try to spread fear and panic when it's proven this event has no environmental degradation impact.  They need a refresher on the rules so they can stop spouting crap from their mouths. 


Apparently they do know the rules and the industry forgot that they were to abide by them. Fact: The industry is on an honor system. I work in that dishonorable 'honor system'. It's as corrupt as it comes. Trevor, get a grip, the industry does do some stupid stuff and yes it will become public. If YOU didn't do it, then good for you. Others will. It's oil and gas my friend and we cut every corner there is. Have you cut corners?



COGCC even admits spreading of cuttings! What they don't talk about are the produced water trucks that open the valves and dump the fluids as they drive in the fields. The truth is the truth and the State must live up to their failures. Admit it COGCC and move on. The industry is not perfect and I've seen it first hand out in the field where I work that this happens. It saves about $20,000 to drive out int he field and dump it. Kudos to Davis and Wockner for their approach and revealing what really happens out in the field! Come on out , if you don't believe it. Yes, I work in the industry...


William if you really did work out here you would know that there is no way any trucks would be off location on the Guttersen. You're a phony for sure.


If no trucks are ever off location, then how do 'we' dump/spread drill cuttings out in a field? That's the reality of this industry, you claim that you know none of these types of things happen at any level. Maybe not your operator, but others do it. What's phony are the people that deny these things never happen.


Besides being a phony, you also can't read very well. I said that trucks aren't off location on the Guttersen ranch. You know, the ranch that this whole article is based on. I know they spread mud(that's what people who actually work in the industry call "cuttings") in some fields. They spread it right next to my house in fact. I even granted them permission to spread the mud from our wells back on our property. Some people go and pay money for bentonite at garden stores and I get the benefits of it and a nice check! Tell me mister insider, what do you do in the patch?


Do you not know that 'cuttings' are generally laden with strontium and barium, of which most often are radioactive isotopes? Please refer to the COGCC's website where an operator who was recently given an NOAV for non permitted dumping of 'cuttings' and/or 'muds' (as listed on the COGCC forms (maybe you don't read those?) The muds/cuttings WERE radioactive and confirmed as such by the COGCC inspector. Do you not know that NORMS occur? How good is this mud now for your garden? Get a clue this happens as many crooked things do and you know it. You're just not straight enough to admit the truth.


You forgot to tell me what you do in the oil field. You also forgot to look up what strontium is. Do yourself a favor and check it out. I will admit that crooked things happen every day. There are people who try to portray themselves as "industry insiders" to spread false information on the internet. Pretty crooked if you ask me.


Many valid points here and I will need to make this a multi post due to its length, I work in the industry and can clear up some of the misconceptions around "land spreading/ land application” this is the practice of spreading drilling waste on the land for both disposal and beneficial purposes. First, William the state (COGCC) does allow for the spreading of drilling waste on land under the 900 series rules. To look this up go to the COGCC home page click rules then click 900 series rules. Rule 907 is the one you want. Phil you are right about Guttersen, anyone who goes to as much trouble posting signs around their ranch warning people of the consequences of trespassing is surely aware of everything going on, so the likelihood of illegal dumping on his place is very low. However you did misspeak when you said mud and cuttings are the same thing, perhaps when the drilling waste was contained in a reserve pit it was a little more ambiguous, but with the advent of the closed system "pitless" drilling the phases of drilling waste are more clearly defined. Because a closed system well separates the different materials you have the shale shaker that separates the mud form the cuttings and the driers and centrifuges that sperate the mud from the water. The cuttings are just that tiny pieces of rock, shale and earth that are recovered from the hole. The (mud) is the bentonite clay that is used for drilling and really sloppy think organic peanut butter right after you mix in the separated water on top. And the water is well water. When discussing (off-site) disposal here is some clarification while they (operators) are allowed to spread mud and cuttings on the lease itself they are also allowed to land spread those drilling waste on anyone’s pasture provided they have; written permission from the landowner (who they usually compensate around 3-4k per well site) (please don’t let them spread for free), submitted a waste management plan to the COGCC, and ensure that the receiving soil after application meets table 910-1 constituent levels. (Table 910-1 is found at the very bottom of the 900 series rules)


How it works (from a closed system well)Cuttings phase- dump trucks come to the well site and load up the cuttings then take it to a pasture and dump it out then usually the landowner loads it up in a manure spreader and spreads it out then disks / plows it in. Mud phase is usually collected in a Hydrovac / supersucker then transported out to the same pasture where it is dumped then directly incorporated. The water phase is taken form the well site by those big water haulers and dumped usually without incorporation then after about 10 days or so the area is sampled (supposed to be sampled) to ensure it meets 910-1 standards. To the statement about the cuttings containing Barium and Strontium. The COGCC requires testing of BTEX, heavy 8 metals, TPH, SAR and a few others. Their allowable levels are some of the most stringent in the US. The NORM levels of cuttings are not usually higher than typical background levels, that’s not to say the operators can’t find a way to screw it up they are notorious for that . To the statement that drilling mud is not a beneficial amendment I will say this. The cuttings portion is made of rocks and earth this is not of benefit to soil. The drilling mud is made of bentonite clay which is found in pond sealers and natural toothpaste. It does not add any nutrients to the soil, however it does add to the water retention properties if applied to sandy soil and allows the farmer to use less fertilizer because less of it is leached threw the sand. HOWEVER! For all you fractivists here is a little inside info that you may find informative. First off in the article Kerr is quoted as saying the operators obtain a permit before land application occurs. This is not true Rule 907 d. B. v. states “Approval. Prior Director approval is not required for reuse of water-based bentonitic drilling fluids for land application as a soil amendment.” No pre approval permit was given by the state for this operation. Second Rule 907d.(3) states that “water based bentonitic drilling fluids may be disposed of as follows” it goes on to describe all the ways that disposal is allowed. The point is that only drilling mud is allowed to be land applied the drill cuttings are separate and not intended for this purpose as they provide zero beneficial reuse. The reason for this is that when the rules were written the primary method for storage of drilling fluids, mud and cuttings was in a reserve pit built on site where the water would evaporate then a vacuum truck would come and suck out the muds and land apply them the cuttings were always left in the bottom of the pit and buried. However with the rise of the closed loop drilling there was no place to store (bury and dispose) of these cuttings so the operators made the assumption that if it came out of the well bore during drilling than it must be covered under 907 d. B. v. which it is not. Hope this post clears up some questions.



Attn: Doug Flanders, even the COGCC states in their reports that portions WERE IN FACT related to oil and gas operations. You are as they come for COGA - inept!



Hoorray Sierra Club!  Seems like they are the only groups doing anything to show how bad the situation is! I've seen Shane Davis present and I'm amazed every time! Go gettem!
