• 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.

  • 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
  • Can hydraulic fracturing fluid migrate into a fresh groundwater zone?

    Fracturing fluids can enter a fresh groundwater zone if there is sufficient bottom hole pressure to raise the fluid level from the fractured zone to the fresh groundwater zone, and there is a conduit through which the fluid can flow such as an open annulus between the casing and the formation.  Fluids may also enter fresh groundwater if there is a hole in the casing above the depth of the groundwater zone and the cement outside of the casing is not adequate to prevent fluid flow between the casing and the formation. However, under normal circumstances hydraulic fracturing fluid is confined to the inside of the production casing, the formation being treated and nearby formations. Read more...

  • 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

  • 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.

1/7/2014 University of Oklahoma offers free course to public

The University of Oklahoma is offering an on-line course on "Hydraulic Fracturing and Water Resources", free of charge to the public.  The course begins January 13th.  You can register for the course at https://janux.ou.edu/landing .  This is a good opportunity to learn more about the process of hydraulic fracturing and the water resources related to the process.
