Texas fracking sand errors

Summary: FracFocus disclosures that misreport sand and water percentages undermine the integrity of the fracking chemical data. Open-FF¹ found 1341 such disclosures in Texas by 213 operators and we summarize them here.

The typical relationship between water and sand throughout FracFocus is about 88% to 11%. As we explored in previous posts, we have found a large number of disclosures that are very different from that typical water-dominated profile. Instead, companies report that sand dominates the fracking job. These are most likely errors and are often associated with other errors. (We note that these are disclosures without carbon dioxide or nitrogen gases, which may have slightly higher percentages.)

The operators with the most disclosures on this list are:

Operator Name
Occidental Oil and Gas                         93
COG Operating LLC                              91
Magnolia Oil & Gas LLC                         90
Pioneer Natural Resources                      72
ConocoPhillips Company/Burlington Resources    62
Encana Oil & Gas (USA) Inc.                    56
Endeavor Energy Resources                      53
Verdun Oil Company                             38
XTO Energy/ExxonMobil                          35
Devon Energy Production Company L. P.          31

The following table lists individual sand-dominated disclosures found in a FracFocus download from Aug. 17, 2024. Although the topic of previous posts were those disclosures with greater than 50% sand, we include disclosures that are greater than 40%. We do this because, statistically, a value of 42.5% sand has a z-score over 3.0 and is generally considered an outlier. Users of these data may want to look more carefully at these marginal values.

FracFocus Support has indicated that they will alert companies to the sand-dominance issues and we hope companies will correct these disclosures. The status of these disclosures shown in this report is a snapshot (Aug 2024) and hopefully will be corrected. Open-FF keeps a running tally of all such FracFocus disclosures and we note when they are corrected. To see the most updated status of Texas sand-dominated records, visit this link.
