Report of FracFocus disclosures published the week ending May 24, 2021

This report summarizes the fracking jobs published this week at FracFocus, the industry-funded chemical disclosure instrument. It includes the Who, What and Where of recent fracking activity: the operating companies, the chemicals they use (including quantities), and where these jobs are located.

This report is produced by Open-FF, an open source, public service project to make the FracFocus data more usable. The nature of the fracking chemical data is complicated and can be difficult to make sense of; Open-FF aims to make it those data more digestible. In addition, FracFocus disclosures are plagued by inconsistencies, ambiguous and missing values and many obvious data errors; Open-FF flags and filters many of those problems. Our hope is that these reports give readers both big-picture perspectives of industry activities as well as enough detail to dig deeply into specifics such as individual chemicals, fracking job, or company.

In this report:

Water use reported in these 355 disclosures

The x-axis is log transformed to show the whole range of water use. $10^{4}$ corresponds to 10,000 gallons; $10^{6}$ is 1,000,000 gallons; $10^{7}$ corresponds to 10,000,000 gallons. Thick vertical lines indicate 25, 50 and 75% percentiles for this week's disclosures. 
 -- 25%:  7,508,495 gallons
 -- 50%:  13,290,690 gallons
 -- 75%:  19,230,933 gallons
 -- max:  45,448,555 gallons
 -- TOTAL 4,781,799,582 gallons

Recognized Chemicals of Concern used in these disclosures

The following table is based on lists of chemicals that have health or environmental effects: SDWA, CWA, Proposition 65, and TEDX.

CID bgCAS record count percent rank of biggest Chemical Name mass of biggest (pounds) SDWA CWA CA Prop 65 TEDX FF history ChemID link
Column Description
CID is the chemical ID used in the disclosure table
bgCAS is the CAS registration number of the chemical
record_count indicates the number of records in this week's disclosures. A given chemical may appear more than once in a disclosure
proportional rank of biggest how the largest max from this week compares to the rest of FracFocus data (through last update). Ex. 95.0 means that this mass was in the top 5% of all uses ever recorded in FracFocus. If there are records with values of 90% or more, a list of all disclosures are in a table later in this report.
Chemical Name is one of the common names for the material
max mass is the single greatest mass of the chemical in this week's disclosures (in pounds)
SDWA CWA indicates if the chemical is on the Safe Drinking Water Act list or the Clean Water Act list (compiled by the Wylie Lab)
CA Prop 65 indicates if the chemical is on California's Proposition 65 list
TEDX indicates if the chemical is on The Endocrine Disruption Exchange list

Proprietary labeling

FracFocus allows disclosures to hide the identity of chemicals that companies claim are business secrets. This practice has been controversial since the beginning of FracFocus and there have been purported measures taken to reduce the proprietary claims. Nevertheless, they are still commonly used. The following summarizes how much the past week's disclosures hid chemical identity with these claims. The individual disclosure listing later in this report specifies the percentage of chemical records that are hidden by these claims for every disclosure.

Open-FF detects proprietary claims solely by the terms used in the CASNumber field. Other fields may also indicate such claims but are ignored here, so these numbers are conservative.

Ingredient names used for proprietary records for this week's disclosures

Because these are proprietary claims, the reported ingredient name will not be specific, just a general class.

In some cases, companies do not report the PercentHFJob or report 0.0% for proprietary records. We use 0.0 pounds for those records in the following table.

Individual disclosure listings

Notes:

Listing of chemicals in individual disclosures: In the table below, individual fracking disclosures are identified by APINumber. If you are interested in seeing the details of the raw data, use that APINumber at the FracFocus "Find a Well" site. That search site will serve pdf files of individual fracking events to your computer with most of the same raw data available used here. However, mass of chemicals is not available from these pdfs.

Maps: In the table below, a link is provided to a Google map/satellite view of the location provided in the disclosure. Many recently published fracking sites are newer than the satellite image that Google uses, so the well pad may not be visible. However, you can still view the geographic context of the drilling site.

Listing of all new disclosures published this week

Color coding of cells indicates conditions of particular concern:

  • FID - Fracking job ID number (not used yet)
  • Water volume - volume in gallons of the water base fluid used in a fracking job
    • light blue: especially large fracking carrier (>30 million gallons)
    • red: no data or a report of ZERO gallons of water. This prevents the calculation of chemical mass
  • TVD - True vertical depth (feet)
    • red: no data or a report of ZERO feet.
    • yellow: likely error: deeper than deepest oil well (35,050 ft.)
  • Percent proprietary - proportion of chemical records for which identity is hidden
    • light pink: at least 10%
    • pink: at least 25%
    • red: at least 50%
  • End date - Last day of job
    • tan: more than one year to publish the disclosure
    • brown: more than two years to publish the disclosure
    • light blue: end date is in the future
  • Total percentage ("perc sum") - the sum of all records in a disclosure should be 100% (within a tolerance)
    • yellow: less than 90%
    • orange: greater than 110% - often caused by a "system approach" entry error: duplicates of some chemical records
  • CIDs in disclosure - see the Chemicals of Concern table above for more information

The following list is the most recently published fracking events. Note that these are still raw names and numbers and have not yet been checked for validity.
