• 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.

Find Well

Search for nearby well sites that have been hydraulically fractured to see what chemicals were used in the process.

  • Will FracFocus 2.0 convert a FracFocus 1.0 Excel template to the new XML schema?

    The FracFocus system does not have a utility to convert FracFocus 1.0 Excel templates to FracFocus 2.0 XML files.  However, if you have someone who can develop a program to do so it should not affect your FracFocus 2.0 submission provided the resulting XML file meets the schema as shown at the following link:



  • Do states conduct ongoing testing of water wells and oil and gas well construction?

    It depends on the state. When it comes to water wells, many states have water well construction standards but not routine testing requirements. As regards the construction of oil and gas wells, all states have well construction requirements.  These can be reviewed by going to the Regulations by State page, selecting the state in question and then selecting View Regulations.

  • What happens to chemicals after they are pumped downhole?

    Chemicals used in hydraulic fracturng are often transformed or degraded by their interaction with formations and formation fluids.  For many chemicals of concern a recent presentation made by Dr. Angus McGrath of the environmental consulting company Stantec entitled "Fate and Transport of Select Compounds of Interest in Fracing Fluids" describes the fate of chemicals.  It is available on the USEPA website at

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.
