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?




Fracking and drilling
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.
