"The possibility of radioactivity transport in the groundwater system as the result of a hypothetical maximum credible gas leak was evaluated." "The present study confirms the low radiation levels in the groundwater predicted in the initial calculations." (from Summary)

"CER Geonuclear has developed, in cooperation with the Atomic Energy Commission, a set of detailed plans utilizing nuclear explosives for an underground engineering experiment called project Rio Blanco. The overall objective is to prove the commercial feasibility of using nuclear explosives to recover commercial quantities of tightly held natural gas in the Piceance Basin."

A report regarding a survey of the condition of wells and springs in the Rio Blanco County, in N.W. Colorado.

The Piceance Basin in Colorado contains an estimated 600 trillion cu ft of natural gas in place. Both the Rulison and Rio Blanco events have been detonated to determine the feasibility of nuclear fracturing to stimulate natural gas production in this basin. A demonstration program to test the relative effectiveness of massive hydraulic fracturing (MHF) to achieve natural gas production stimulation from the same gas reservoir is presented. Details are included on MHF design parameters, including surface and subsurface equipment, pumping requirements, evaluation of fracturing results, and all associated test programs; site characteristics and preparation; proposal for gas utilization program; environmental surveillance and comparative analysis of environmental aspects of MHF and nuclear stimulation; gas delivery estimates; project administration; and costs and scheduling.
