In situ bulk densities of the Devonian shale section penetrated by the Columbia Gas Transmission Corp. 20402 well, Lincoln County, West Virginia, were determined using the U.S. Geological Survey-LaCoste and Romberg/sup 2/ borehole gravity meter. Densities from two gamma-gamma logs, run by different companies, were also available. A cumulative difference of .034 g/cm/sup 3//1000 ft (.112 g/cm/sup 3//km) exists between the two gamma-gamma logs. The two intervals of lowest density derived from the borehole gravity data show higher densities on both gamma-gamma logs, possibly indicative of the deeper investigation radius of the borehole gravity meter. In most intervals, higher gamma-ray intensity correlates with lower density, indicating that organic content is the primary variable affecting both bulk density and uranium concentration.
