typical profile of fracking water, sand and additives

Open-FF1ย has found many chemical disclosures that misreport concentrations of fracking sand and water in Texas. These errors seriously distort the chemical profiles of the fracking jobs.

A few months ago we reported on 5 notable disclosures of COG Operating, LLC. Here, we provide a more complete summary of a set of that company’s FracFocus disclosures from their Texas fracking jobs. As we pointed out in a recent post and shown in the first figure, the typical profile of fracking fluids is dominated by roughly 88% water, followed by 11% sand2 and the rest is chemical additives3. But the disclosures highlighted in this post differ substantially from that profile because sand dominates the fracking fluid instead of water.

Reported percentage of sand in fracking fluid of COG Operating jobs in Texas

As you can see from the next figure, most Texas fracking jobs from COG Operating (empty circles) have sand percentages of about 10%. But for 85 disclosures (filled circles), sand makes up over half of the fluid4. As we outlined earlier, we believe these sand-dominated disclosures are an error. Furthermore, this fundamental error has ripple effects throughout the other records.

Summary values are shown in table at the bottom of this post and fracking jobs are mapped here5:

FracFocus Support has informed us that they are preparing an alert to companies about these sand-based issues.6 We hope the COG Operating will correct these disclosures to reflect the actual percentages and masses used in those fracking jobs. Without accurate disclosures, FracFocus is not a trustable instrument. Open-FF monitors changes to FracFocus and we will update this post if COG Operating modifies these disclosures.

  1. Open-FF is a public service project to foster better understanding of fracking chemicals disclosed at FracFocus. See theย Open-FF homeย for more information and links to resources โ†ฉ๏ธŽ
  2. The CASRN for sand is 14808-60-7 and is commonly called “crystalline silica, quartz” in FracFocus. โ†ฉ๏ธŽ
  3. Weโ€™ve been told that foam-based carriers, that appear in about 2% of FracFocus disclosures, may tolerate more sand. These disclosures use carbon dioxide or nitrogen gases to replace a substantial fraction of the water carrier. None of the disclosures in this report use those gases. โ†ฉ๏ธŽ
