Uranium Content of Chattanooga Shale in East-Central Tennessee and Southern Kentucky (open access)

Uranium Content of Chattanooga Shale in East-Central Tennessee and Southern Kentucky

From abstract: Uranium assays of all the samples collected by the Geological Survey from the Chattanooga shale in east-central Tennessee and southern Kentucky from 1947 to 1949 are assembled here, and conclusions are drawn concerning the distribution of the uranium. The 1108 assays from 80 localities provide reasonably reliable information on the stratigraphic and regional variations of the uranium content.

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: July-September 2003 (open access)

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: July-September 2003

CO{sub 2} emissions from the combustion of fossil fuels have been linked to global climate change. Proposed carbon management technologies include geologic sequestration of CO{sub 2}. A possible, but untested, sequestration strategy is to inject CO{sub 2} into organic-rich shales. Devonian black shales underlie approximately two-thirds of Kentucky and are thicker and deeper in the Illinois and Appalachian Basin portions of Kentucky than in central Kentucky. The Devonian black shales serve as both the source and trap for large quantities of natural gas; total gas in place for the shales in Kentucky is estimated to be between 63 and 112 trillion cubic feet. Most of this natural gas is adsorbed on clay and kerogen surfaces, analogous to methane storage in coal beds. In coals, it has been demonstrated that CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. The concept that black, organic-rich Devonian shales could serve as a significant geologic sink for CO{sub 2} is the subject of current research. To accomplish this investigation, drill cuttings and cores were selected from the Kentucky Geological Survey Well Sample and Core Library. Methane and carbon dioxide adsorption analyses are being performed …

Cabinet. (open access)

Cabinet.

Patent for a cabinet meant to contain "screws, bolts, rivets, and similar articles, and has for its object to provide a case for the storage of such articles by means of which the different articles are kept separate one from another, while at the same time ready access may be had to any one of the storage-compartments" (lines 9-15). It is circular and has a wheeled base.
