A very detailed geochemical study of the Eastern Gas Shales has been performed and, as a consequence, new, more accurate values for indigenous gas have resulted, along with an identification of the high-potential zones of the Appalachian, Illinois, and Michigan Basins. However, indigenous gas does not equate to recoverable resource in the Devonian shales. As has been mentioned earlier, the shale matrix is very tight and most of the gas is assumed to be locked in this matrix. The key to recovering this resource is either to drill in highly naturally fractured zones where the gas has been released from the matrix and has accumulated or to effectively stimulate the shale zone. An integral part of the DOE program is stimulation research. The factor that is the overriding constraint on enhanced drilling activity in the Devonian shales is economic recovery and, until efficient and effective stimulation treatments are demonstrated for shale wells, industry activity will be limited, even though the resource potential of the Devonian shales is tremendous.
