Hundreds of companies have registered tens of thousands of oil and natural gas wells on a website called FracFocus.org.
This is where you can see the content of the fluids that fractured these wells. The service is managed by the Ground Water Protection Council and the Interstate Oil & Gas Compact Commission.
WPX was one of the first companies to register wells, including ones from our San Juan Basin operations in New Mexico.
You can see our disclosures at www.fracfocus.org.
