This visualization shows the amount of water used to frac each of the wells drilled within the municipal boundaries of Broomfield, Colorado since 2017. The data is grouped by operator, with the most recently fracked wells shown first. In total, 848.76 million gallons of water have been used to frac these wells, with a median of 12.57 million gallons of water used to frac each of the 67 wells.
This visualization shows the amount of water used to frac each of the wells drilled within the municipal boundaries of Erie, Colorado since 2017. The data is grouped by operator, with the most recently fracked wells shown first. In total, 626.48 million gallons of water have been used to frac these wells, with a median of 9.64 million gallons of water used to frac each of the 57 wells.
We’ll be updating this FAQ as we get additional information from the various involved parties. Where possible, links to additional/source material have been provided.
“Modern high-volume hydraulic fracturing is a technique used to enable the extraction of natural gas or oil from shale and other forms of “tight” rock (in other words, impermeable rock formations that lock in oil and gas and make fossil fuel production difficult). Large quantities of water, chemicals, and sand are blasted into these formations at pressures high enough to crack the rock, allowing the once-trapped gas and oil to flow to the surface.”
In Part I, Part II, Part III, Part IV, and Part V of this series, we showed that each hydraulic fractured well permanently poisons millions of gallons of water.
Once again, the Erie community is under assault with the 26-well proposed Draco pad and an additional 18 wells proposed to be drilled at the Coyote Trails pad. Let’s look at the data for the Cosslett East wells, completed in September 2023.
A total of 178,725,812 gallons of water were used to drill these wells, with a median of 13,261,197 gallons per well. This is 18.4% less than the median water use for the original Cosslett wells, but without completion information for these wells (the data is not yet available at the ECMC), it’s not obvious why. For reference, here is a visual representation of the two sets of directional wellbores:
A comparison of the directional wellbores for Cosslett (left) and Cosslett East (right).
Once the completion data for the Cosslett East wells becomes available, we’ll update this analysis.
In Part I, Part II, Part III, and Part IV of this series, we showed that each hydraulic fractured well permanently poisons millions of gallons of water.
Now that Occidental is fracking the wells at Mae J and Papa Jo / Shumaker, there’s a renewed interest in the amount of water used by hydraulic fracturing, so let’s take a look at the 12 wells drilled at the Cosslett pad by Crestone Peak Resources.
By using more water than any other pad we’ve examined in this series, it’s once again worth saying out loud:
Crestone Peak Resources has used one hundred seventy-five million, five hundred thirty-four thousand, six hundred and seventy-four gallons of water to frack the twelve wells at Cosslett.
A total of 175,534,674 gallons of water, with a median of 16,252,811 gallons per well. It sounds like we’ll expect Occidental to use a similar quantity of water to drill the 12 wells at Mae J.
In Part I, Part II, and Part III of this series, we showed that each hydraulic fractured well permanently poisons millions of gallons of water.
Now that the data for the drilling at Broomfield’s Interchange B pad has become available from FracFocus, a quick calculation shows Extraction Oil & Gas has used 81,837,881 gallons of water to frack the 10 wells at the Interchange B pad.
Once again, let’s say it out loud:
Extraction Oil & Gas has used eighty-one million, eight hundred thirty-seven thousand, eight hundred eighty-one gallons of water to frack the ten wells at Interchange B.
Extrapolating to the remaining 74 wells to be drilled, we’re expecting Extraction to use just over 600 million gallons of water on this project. Note the difference between the water used for the C wells in the Codell formation versus the N wells in the Niobrara formation.
In Part I and Part II, we showed that each hydraulic fractured well permanently poisons millions of gallons of water. This week a new Duke University study was released, claiming “the amount of water used per well for hydraulic fracturing surged by up to 770 percent between 2011 and 2016 in all major U.S. shale gas and oil production regions.”
Since it has been a while since we’ve gathered this data from FracFocus, a quick calculation shows Extraction Oil & Gas has used 102,044,434 gallons of water to frack the 10 wells at the Coyote Trails pad just east of Erie, Colorado in unincorporated Weld County.
Extraction Oil & Gas used 102,044,434 gallons of water to frack the 10 wells at Coyote Trails.
Once again, let’s say it out loud:
Extraction Oil & Gas has used one hundred two million, forty-four thousand, four hundred and thirty four gallons of water to frack the ten wells at Coyote Trails.
Keep in mind that these 10 wells are just the beginning; 4 Form 2s have already been approved and another 24 are pending for this location.

On February 12, 2018, historical impacts were discovered during abandonment activities at the Champlin 41-4 #1 production facility. The release became State reportable on February 14, 2018, due to the quantity of impacted soil excavated. Soil excavation activities are ongoing and will be summarized in a forthcoming Supplemental Form 19 Spill/Release Report.
We received the following post from an O&G industry worker on our Facebook page:
Results coming in from air quality tests near Parachute, CO shows “little risk”…”According to the data, all air concentrations of individual and combined volatile organic compounds (VOCs) were below long-term, non-cancer health guideline values established by state and federal agencies.” But I’m sure you and ECBU will find some flaws with the tests to discount the results… Still, it is good to have more data points.
For the purposes of this discussion, let’s refer to the following documents:
In a recent tweet for the Erie Protectors (follow us @ErieProtectors), I mentioned that there are 13,103 producing wells in Weld County alone. Another 8,386 are shut in. Another 4,377 have been plugged & abandoned. Another 1,143 are currently being drilled.
Well statistics from the COGCC Daily Activity Dashboard, taken on January 16, 2018.
This month, I’d like to focus on the last stage of production – the plug & abandon operation. OSHA has a concise definition of the process :
A well is abandoned when it reaches the end of its useful life or is a dry hole.
The casing and other equipment is removed and salvaged.
Cement plugs are placed in the borehole to prevent migration of fluids between the different formations.
The surface is reclaimed.
By the industry’s own admission, “end-of-well operations are often more difficult than initial well construction.” Let this be a cautionary tale told in three parts.
The Vessels Minerals site is 25 yards from the Aspen Ridge Preparatory School playground.
Crestone Peak Resources began plug & abandon operations at the Vessels Minerals site just east of Aspen Ridge Preparatory School on September 12, 2017. The same day, an observant resident filed a complaint with the COGCC about “an odor that is permeating from the site that can be smelled in the school parking lots.” When the COGCC sent out an inspector the following day, he had this to report in a notice of alleged violation (NOAV):
COGCC Staff also observed […] children playing in the playground and watching the rig crew’s operation, and volatile organic compounds (“VOCs”) visibly drifting toward the children in the playground.”
While Crestone took corrective action the same day and installed emission control equipment, they had every intention of venting VOCs 25 yards from a playground for 8 weeks while they conducted business as usual. The community was only made aware of the NOAV when an Erie Protector found it online almost two months later.
Lessons learned? If you see it, report it. The rules & regulations are inadequate to protect us. The industry has complete disregard for the communities in which they operate.
The “Oil & Gas Site” designation on the Erie Highlands Concept Plan
Our second tale comes from an idyllic suburban development just east of Grandview in Erie. The concept plan for Erie Highlands includes three innocuous “oil & gas site” designations in what appear to be pocket parks and open space. Imagine the surprise of recent owners of near-million dollar properties when fourteen characters on a pretty picture turned into a work over rig less than 100 yards from their back doors, especially when realtors had told them the wells were already plugged.
The workover rig at the William H. Peltier #2 site, originally completed in 1986.
Lessons learned? Do your homework. Self-serving realtors and developers have no interest in providing more than the minimal state-mandated disclosures about nearby oil & gas developments. They will pretend property values are unaffected and will deny community meetings to inform residents of O&G operations. When you’re looking for a new home, visit the COGCC online map at http://cogccmap.state.co.us/cogcc_gis_online/ and find out where historical, current, and future O&G development may impact you.
Saulcy 4-1 and surfacing liquid near well location.
Our final tale comes from Windsor, where in October 2017 “an old well that was plugged in 1984began spilling oil on Colorado 60 east of U.S. 287.” Operators in the region were quick to respond to the well that had been drilled by an unknown operator in the 1920s or 1930s, but “an estimated 5 gallons to 6 gallons every minute” were spilling from the well.
Lessons learned? Oil & gas is forever. This blight upon our neighborhoods, open spaces, and environment has far-reaching implications. Operators come and go, but their impacts will remain long after we forget their names.
