Interchange – Erie Protectors

This map depicts the existing oil & gas infrastructure in and around the City and County of Broomfield. While the southwestern portion of Broomfield lies outside of the Denver Julesburg Basin, there are still 70 producing wells at 25 active locations, and 144 plugged and abandoned wells that will require maintenance and inspection forever.

As a part of a Comprehensive Development Plan (CDP) negotiated with the City and County of Broomfield, Extraction Oil & Gas drilled 82 wells along the north edge of Broomfield in 2019 and 2020, during which time 299 complaints were filed with the ECMC regarding noise, odor, and other issues. As shown in the inset maps at bottom right, 12 of the 82 wells are in a “suspended operation” state, meaning the wells were only drilled to a depth of 1,600 ft rather than their full depth and were not hydraulically fractured (the remaining 70 wells were drilled to an average depth of 7,760 ft.) In April 2025 Form 5B filings, Extraction says it “intends to utilize the wellbore[s] in the future.”

Also shown at the top of the map is the recently approved Draco Oil & Gas Development Plan (OGDP), where 26 5-mile wellbore laterals will be drilled across Erie and into Boulder County.

The data was compiled using GIS data downloaded from the Colorado Energy & Carbon Management Commission (ECMC) web site at https://ecmc.state.co.us/ on May 3, 2025.

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.

We’ll keep you posted of the water usage as Extraction progresses with their comprehensive drilling plan.
