A geochemical survey to assess and evaluate the Devonian oil shale resources of north Alabama, northwest Georgia, and south-central Tennessee has been performed. Information is provided on the location and extent of the more favorable kerogen-bearing Devonian shale, oil and uranium content of the shale, trace metal and standard rock analyses for shale, data on the physical properties of the shale rock, mineralogy of the shale, chemical properties of the oil, and other pertinent data deemed necessary for resource development. The results indicate that the oil yield from areas underlain by Chattanooga Shale can be divided into areas having greater than 7 g/t and areas having less than 7 g/t. In general, the oil yield by Fischer assay of samples from the folded Appalachian Valley and Ridge and the Appalachian Plateaus provinces is poor, all having less than 5 g/t and most samples closer to 0 g/t. The extreme variance of Fischer assay values in the Chattanooga Shale could be the result of several parameters that influenced the nature of the shale: type of organic material in the shale; percentage of organic carbon present in the shale; increase in the amount of clastic material in the shale; paleogeographic position of the Devonian shale during regional deformation; or maturity of the kerogen. Excellent preservation of organic material in the shale samples from north Alabama and south-central Tennessee (average TOC = 16.02 wt %) and the high quality of preserved organic matter (Type I and Type II kerogen) imply that anoxic conditions must have existed in this marine environment. Based on the areal distribution of the Chattanooga Shale, its average thickness, and its average oil yield, we estimate that the Chattanooga Shale, having less than 150 ft of overlying rock covers an area of at least 391,500 acres in the FCA and immediate surrounding area. In-place shale oil resources are estimated at 2.9 billion barrels or 7400 barrels per acre.
