Summary: Trade secrets in FracFocus, an instrument of transparency, explicitly conceal the identity of chemicals. This masking has long been controversial. Open-FF found 36,300 trade secrets in Utah records. These records spanned all years and 91.3% of published disclosures. About 47,400,000 pounds of trade secret chemicals have been reported. In this post, we summarize the broad patterns of trade secret use in Utah between 2014 and early 2025. We also illustrate the types of trade secrets patterns in the state with local examples. This post is part of a series reporting on “holes” in FracFocus.1
FracFocus is a public online database that provides information about the chemicals used in hydraulic fracturing (fracking) across the United States. While intended to promote transparency, a significant portion of the disclosed chemical information is often withheld as “trade secrets.” This practice has been the subject of debate of how to balance industry’s need to protect proprietary formulas with the public’s right to know about substances injected underground.
Background
- The analysis on this page used FracFocus data download on April 20, 2025.
- Labeling of trade secrets is not standardized in the FracFocus data. Open-FF curates the data to make examining all trade secrets possible. See the documentation.

Utah’s frequency of trade secrets is the highest in the nation.
Examples of Trade Secret Use in Utah
We summarize specific examples to highlight the various ways the trade secret designation is applied. Here are some typical scenarios we observed:
Large Percentage of Records as Trade Secrets
In some disclosures, a substantial proportion, sometimes even the majority, of the listed ingredients are marked as trade secrets. This leaves the public with very little information about the chemical composition of the fracturing fluid used in that specific well.
Example: Consider the well operated by Middle Fork Energy Parterns, LLC in Uintah County. (Click on images to open map and disclosure.)
In this disclosure, 66% of ingredients are listed as trade secrets. For some of these chemicals, the name given seems to be a legitimate chemical name. However, FracFocus instructs us to give primacy to the CASNumber. Even if the name is correct and specific, the “Proprietary” label makes the identity unclear – the opposite of transparency. The list of trade secrets for that fracking job are:
| TradeName | IngredientName | CASNumber | mass (pounds) |
|---|---|---|---|
| Other Chemical(s) | polymer | Proprietary | 31,500 |
| Other Chemical(s) | inorganic salt | Proprietary | 19,400 |
| Other Chemical(s) | distillates (petroleum), hydrotreated light | Proprietary | 18,700 |
| Other Chemical(s) | paraffinic oils | Proprietary | 7,590 |
| Other Chemical(s) | polyoxyethylene monooleate | Proprietary | 2,370 |
| Other Chemical(s) | sodium polyacrylate | Proprietary | 2,300 |
| Other Chemical(s) | ammonium chloride | Proprietary | 1,380 |
| Other Chemical(s) | sorbitan oleate | Proprietary | 990 |
| Other Chemical(s) | poly(oxy-1, 2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-,ether with d-glucitol (2:1), tetra-(9z)-9-octadecenoate | Proprietary | 689 |
| Other Chemical(s) | 12-hydroxystearic acid-polyethylene glycol copolymer | Proprietary | 689 |
| Other Chemical(s) | sodium hydrogensulphite | Proprietary | 592 |
| Other Chemical(s) | alcohols, c12-14-secondary, ethoxylated | Proprietary | 495 |
| Other Chemical(s) | isopropanol | Proprietary | 194 |
| Other Chemical(s) | acrylamide | Proprietary | 96 |
| Other Chemical(s) | ammonium acrylate | Proprietary | 96 |
| Other Chemical(s) | diethylene triaminepentaacetic acid, pentasodiumsalt | Proprietary | 53 |
| Other Chemical(s) | potassium acetate | Proprietary | 32 |
| Other Chemical(s) | dioxane | Proprietary | 1 |
| Other Chemical(s) | ethylene oxide | Proprietary | 1 |
| Other Chemical(s) | polyethyleneglycol | Proprietary | 1 |
Individual Trade Secret Records That Are High Mass
Occasionally, a single ingredient marked as a trade secret represents a significant mass or percentage of the total fluid volume reported in a disclosure. This means a large component of the fracturing fluid’s composition is entirely unknown.
Example: Consider the well operated by Scout Energy Partners in Duchesne County.
In this well, a single trade secret entry is reported with a mass of 317,000 pounds, representing a significant portion of the total fluid volume. The chemical identity of this large-mass material is withheld.
Utah has 60 trade secret records with masses over 100,000 pounds.
Systems Approach Disclosures with Trade Secret Records
FracFocus disclosures are often published in the “systems approach” format that decouples product names from chemical identity. FracFocus claims that this practice “decreases the use of trade secrets in disclosures, thereby improving public transparency.” Analyses by Trickey et al. and Underhill et al. disprove that claim across the FracFocus data. Instead, we often find system approach disclosures with multiple trade secret claims – because there is nothing to compel companies to include the chemical identity.
Example: Consider the well operated by Uinta Wax Operating, LLC in Duchesne County.
The disclosure for that well utilizes a systems approach format but still conceals the identity of 13 chemicals, which means 61% of ingredients are listed as trade secrets. The table below lists those records with their quantity.
| IngredientName | CASNumber | mass (pounds) |
|---|---|---|
| methanol | Proprietary | 31,600 |
| polymer | Proprietary | 5,720 |
| organic acid | Proprietary | 572 |
| organic acid salt | Proprietary | unknown |
| inorganic acid salt | Proprietary | unknown |
| proprietary surfactant | Proprietary | unknown |
| urea derivative | Proprietary | unknown |
| proprietary polymer 1 | Proprietary | unknown |
| inorganic salt | Proprietary | unknown |
| organic acid ether | Proprietary | unknown |
| glycol | Proprietary | unknown |
| proprietary amide | Proprietary | unknown |
| petroleum distillates | Proprietary | unknown |
Trade Secret Records Without Any Hints About Material Type
While it is sometimes claimed that operators must supply coarse categories for trade secrets, the data tell a different story. Some trade secret entries provide no descriptive information, such as a functional category (such as “friction reducer,” “surfactant”) or chemical group (“ethoxylated alcohol”), about the material. This makes it impossible to even guess the potential role or nature of the withheld substance.
Examples: The following table lists some of the reported IngredientNames for Utah’s trade secrets that are also reported without informative values for “Purpose”.
| IngredientName | count |
|---|---|
| proprietary | 3828 |
| proprietary ingredient | 548 |
| trade secret | 211 |
| non-hazardous ingredient | 123 |
| non-hazardous substances | 34 |
| proprietary component | 20 |
| non-hazardous | 10 |
Implications for Utah
The patterns and examples of trade secret usage in Utah’s FracFocus data highlight the limitations of the database in providing
chemical transparency. While trade secret protection is a legal right when formalized, its extensive use in fracking disclosures raises questions for regulators, researchers, and the public regarding potential environmental and health impacts. Understanding how and where trade secrets are used is a crucial step in evaluating the effectiveness of public disclosure requirements in the state.
Colorado’s recent law requiring enhanced disclosure in a way that still protects intellectual property may serve as a model to improve overall transparency.
