The Devonian Shale has been recognized as an important source of gas in the Appalachian Basin. The program aids producers in the collection of reservoir data not normally collected and assists in the evaluation of the effectiveness of zone selection, stimulation designs, and methods. A detailed logging, coring, and well-testing program is being conducted on twenty-eight newly drilled wells in three areas of the Appalachian Basin. Production and borehole TV surveys are being conducted on certain existing and newly drilled wells. Zones of gas are being identified. The geology and reservoir characteristics of the wells are being determined through the analyses of geohpysical logs, borehole TV, and surface-well testing data. Perferred wells for study are those with single-zone well completions stimulated by hydraulic-fracturing techniques. Stimulation techniques, selected by the respective producers, are being evaluated using a prescribed well-test analysis procedure to determine their effectiveness.
