• Welcome to FracFocus 2.0! We're excited about our latest upgrades designed to dramatically enhance the site's functionality for the public, state regulatory agencies and industry users. Our user-friendly 'Find A Well' chemical disclosure registry now includes more extensive search options.

    FracFocus continues to evolve and expand, adding more participating companies and reported wells from across the country. Our continued success is the result of nationally recognized organizations working with state governments and the oil and natural gas industry to provide public transparency.

  • This technique uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow, increasing resource production.

    Learn More About Casing
  • Casing is the multiple layers of steel and cement inside the drilled hole used to protect water aquifers. The specific length, thickness, strength and composition of casing is regulated at the state level.

Groundwater Protection: Priority Number One

Oil and natural gas producers have stringent requirements for how wells must be completed. The genesis of these requirements is water safety.

Casing is the first line of defense used to protect freshwater aquifers.

FAQs
  • I just upgraded to a new browser and I am having trouble. What can I do?

    After the upgrade of a browser unexpected issues may occur when working with a data site.  Running in compatibility mode with the new browser may be necessary for a period of time.  If you have recently upgraded your browser software please review the default configuration of the browser to see if you can identify the issues that may be causing your problem.

  • Are the records from FracFocus available in a digital format such as Excel?

    No. FracFocus was originally designed to serve records one at a time in Adobe pdf format in order to ensure accurate, unaltered and uncompromised data. Consequently the chemical information gathered does not currently reside in a database or spreadsheet format.

  • What information is contained in the hydraulic fracturing records?

    The following is a list of elements contained in the hydraulic fracturing records viewable on this site and an explanation of what each element means.

    The header of each fracturing record contains the following information:

    1. Fracture date:  This is the date on which the fracturing associated with the record occurred

    2. State: The  name of the state in which the surface location of the well is located

    3. County:  The name of the county within the state

    4. API Number:  This number is assigned under a system developed by the American Petroleum Institute.  API
    numbers are formatted as nn-nnn-nnnnn-nn-nn with the first 2 numbers designating the state, the second 3 numbers
    designating the county within the state and the next 5 numbers designating the particular well within the county.
    When present, the next 2 numbers are a  directional sidetrack code to designate the number of horizontal or
    directional offshoots from a single vertical borehole and the final 2  numbers are an event sequence code used to
    designate multiple activities conducted at a single well such as recompletion, treatment etc… (A list of the state
    and county codes can be found at http://www.spwla.org/technical/api-codes)

    5. Operator Name:  This is the name of the company

    6. Well Name:  This is typically the name of the property owner on whose land the well is located.  In the
    case of multiple property owners pooled under a single unit, the name of the majority property owner is often
    used.  The number on the well may designate the chronological sequence of wells drilled.
    (Example: The Smith #2 might designate the second well drilled on the Smith lease).  However, this is not a universal naming convention.

    7. Longitude:  This the east-west coordinate location of the well on the earth in degrees, minutes and seconds

    8. Latitude: This is the north-south coordinate location of the well on the earth in degrees, minutes and
    seconds

    9. Latitude/ Longitude Projection:  This is the particular projection method for the Latitude/ Longitude (e.g.
    North American Datum (NAD) 27 or 83)

    10. True Vertical Depth:  This is the absolute depth of the well measured from the surface to the deepest point
    of penetration

    11. Total Water Volume:  This is the total amount of water in gallons used as the carrier fluid for the
    hydraulic fracturing job.  It may include recycled water and newly acquired water.

    12. Production Type:  This designates the well type (e.g. Oil, Gas)

    In addition to the general information shown above, each record contains information about the specific chemicals used during the fracturing process.  The following is a list of the chemical information shown on the fracturing record:

    1. Trade Name:  This is the name of the product designated by the supplier

    2. Supplier:  This is the name of the service company that supplied the product (e.g. Schlumberger,
    Halliburton)

    3. Purpose:  This is the function served by the additive (Trade Name) in the fracturing process (e.g.
    surfactant, biocide etc…)

    4. Ingredients:  This is the scientific name of the chemical (e.g. Ethanol, Naphthalene etc…)

    5. Chemical Abstract Service or CAS Number:  This is a number assigned by a division of the American Chemical
    Society for the purpose of identifying a specific substance.  You can learn more about the toxicity characteristics of chemicals by searching for the chemical using the name or CAS number on the USEPA National Center for Computational Toxicology  website.  USEPA also maintains a Drinking Water Hotline that is available Monday-Friday from 8:30 AM-4:30 PM Eastern time at 1-800-426-4791.


    6. Ingredient Percentage in Additive by % Mass:  This describes the amount of ingredient within the additive
    (Trade Name) as a percent of the total mass of the additive. Note:  Because the % Mass of the additive will be expressed as its maximum concentration, the total % Mass of ingredient percentage may exceed 100%.

    7. Ingredient Concentration in HF (Hydraulic fracturing) fluid % by mass:  This describes the amount of ingredient as a percent of the total mass of the HF fluid including carrier fluid and additives. Note: The total may not equal 100% due to the absence of non MSDS ingredients which may or may not be listed depending upon state reporting requirements.
