Beneath the Surface
The United States holds enough oil and gas to power the country for hundreds of years, and Colorado is at the center of the search for energy resources. Using a controversial process called hydraulic fracturing—better known as fracking—and new drilling techniques, oil and gas companies are able to extract these previously inaccessible fossil fuels. These technologies may be the biggest step yet toward securing our energy independence. But at what cost?
State of change
A quick look at the state rules that regulate fracking.
Oil and gas operators are required to inventory the chemicals at each well site, notify the Colorado Oil and Gas Conservation Commission (COGCC) 48 hours before any frack job, and monitor the well pressure during the fracking process. As of April 2012, Colorado became one of the first states to require its operators to disclose the chemicals in their solutions within 60 days of completing a frack job. “Colorado’s disclosure rule isn’t perfect, but it’s a good step in the right direction,” says Earthjustice attorney Mike Freeman. “The idea is that before you can even figure out how big of a problem fracking is, you need to know what they’re using.”
What’s next?
Setbacks are one of the hottest fracking debate topics in Colorado. The current rules require a drill pad to be set back 150 feet from a building, or 350 feet from buildings in high-density areas. In October, the COGCC launched a process, which may take up to three months, to consider changes to the existing setback rules.

Fracking in the Denver Basin and impacts on Aquifers
The Colo Oil and Gas Commission flow diagram for permitting a fracking well doesn't seem to include any Q/C and Q/A procedures for ensuring that the fracking wells maintain hydraulic pressure (+20000 psi) integrity throughout it's 20 year life. There also is no information on independant staffing that umpire inspections and prepare reports at regular intervals.
The purpose for all this is to enable a shut down of the well if well linings are compromised and cause leaks into aquifers before the volume of the leak so great that the aquifer is contaminated. The well may have to be abandoned and filled with cement to control the leaks. A gas well contractor won't do this voluntarily.
