A recent Federal Power Commission (FPC) feasibility study assessed the possibility of economically producing gas from three Rocky Mountain Basins; the Green River Basin, Wyoming; the Piceance Basin, Colorado; and the Uintah Basin, Utah. These basins have potentially productive horizons 2, 000 to 4, 000 feet thick containing an estimated total of 600 trillion cubic feet of gas in place. However, the producing sands are of such low permeability and heterogeneity that, in general, conventional methods have failed to develop these basins economically. The Natural Gas Technology (NGT) Task Force, responsible for preparing the referenced feasibility study for the FPC, indicates that if effective well stimulation methods for these basins can be developed, it might be possible to recover ultimately 40 to 50 percent of the gas in place.
