Chemical Disclosures Now Available for Cosslett East

On June 27, 2025, Crestone Peak Resources finally submitted the required chemical disclosures for the hydraulic fracturing jobs at Cosslett East, 5 weeks after PSR/FracTracker’s expose on missing chemical disclosures was published on May 20, 2025. This report was submitted 679 days late; it was originally due on August 18, 2024, 150 days after the last well was spud on March 21, 2023. It’s yet another example where the industry is only held accountable by activist organizations where state regulatory agencies fail to do so.

PSR Report: Colorado Oil & Gas Operators Fail to Report Fracking Chemicals

On Tuesday, May 20, 2025, Physicians for Social Responsibility (PSR), PSR Colorado, Colorado Sierra Club, and FracTracker Alliance released a report that highlighted low compliance with a 2022 Colorado law designed to prevent toxic exposure to the chemicals used in hydraulic fracturing.

Of the 1,114 wells highlighted in the report, 14 of them are located in Erie at the Cosslett East #22H-H168 pad, where wells were drilled and hydraulically fractured in 2023.

How much water does fracking use, Part VI

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:

Once the completion data for the Cosslett East wells becomes available, we’ll update this analysis.

How much water does fracking use, Part V

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.
