• FracFocus is continuing to evolve and expand its performance and versatility by providing more than a dozen enhancements including: 

    • Expand the public’s ability to search records
    • Improve data accuracy
    • Provide extraction of data in a “machine readable” format
    • Update educational information on chemical use, oil & gas production    and potential environmental impacts

    These upgrades will be designed to dramatically enhance the site’s functionality for the public, state regulatory agencies and industry users. 

    Adding more participating companies and reported wells from across the country, FracFocus’ continued success is the result of state and federal government agencies 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
  • 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 https://www.spwla.org/content/api-standards-information)

    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.

  • The operator name on the well list does not match the name of the operator on the fracturing record. Can you tell me why?

    The name of the operator on the well list is based on the name used to register the company in the FracFocus system.  However, companies sometimes operate through subsidiaries.  For example Anadarko Petroleum Corporation purchased Kerr Mcgee and still operates wells under the Kerr Mcgee name.  Regardless of the name of the operator on the fracturing record the operator name on the list reflects the name of the FracFocus participating company.

  • I know there are wells in my area that have been fractured, but when I search for them I get no results. Why?

    The most likely reasons are that either the wells were fractured before January 1, 2011 or they have not yet been entered into the system.  Only wells fractured after January 1st will be entered into the system and since the uploading of records began only recently it will take some time before a large number of wells is available.  Please keep checking back as wells are added on a daily basis.

4/12/2016 FracFocus Celebrates Its 5th Anniversary

Oklahoma City, OK - Five years ago, the Ground Water Protection Council and Interstate Oil and Gas Compact Commission partnered with a vision to provide the public a one-stop site to access information on chemicals used in hydraulic fracturing operations by location. The partners launched FracFocus.org, the national hydraulic fracturing chemical disclosure registry on April 11, 2011.
