Drillers in Colorado would have to file a detailed report on the amount and ingredients in the fluids used to hydrofracture wells under draft regulations issued Tuesday.
Colorado, like Texas and Wyoming, is proposing that drillers disclose the constituents of their fracking fluids through — an independent national database. Almost all wells in Colorado, and most in the nation, are fracked — with water, sand and trace chemicals pumped into them to fracture rock and release more oil and gas.
The fluids for about half the wells fracked this year in Colorado have been voluntarily filed with FracFocus, according to the Colorado Oil and Gas Conservation Commission. The FracFocus database can be searched by county and well. A public hearing on the draft rule is set for Dec. 5.
