Modeling Fluid Flow and Electrical Resistivity in Fractured Geothermal Reservoir Rocks

Description: Phase change of pore fluid (boiling/condensing) in rock cores under conditions representative of geothermal reservoirs results in alterations of the electrical resistivity of the samples. In fractured samples, phase change can result in resistivity changes that are more than an order of magnitude greater than those measured in intact samples. These results suggest that electrical resistivity monitoring may provide a useful tool for monitoring the movement of water and steam within fractured geo… more

Results of Toxicity Studies Conducted on Ceriodaphnia dubia and Daphnia ambigua in Support of an Alternate Species Demonstration, January - June 2000

Description: In 1997, the Savannah River Site completed toxicity testing studies on an alternate species, Daphnia ambigua, that we have proposed for use as a toxicity testing organism at SRS. We demonstrated that this species could be cultured in the laboratory and that it was at least as sensitive as Ceriodaphnia dubia to a broad range of toxicants (Specht and Harmon, 1997; Harmon, 1998; Harmon and Specht, 1998; Harmon, Specht and Chandler, 1999). However, it performed better that C. dubia in very soft wat… more
