Estimating the amount of conductive and nonconductive constituents in the pore space of sediments by using electrical resistivity logs generally loses accuracy where clays are present in the reservoir. Many different methods and clay models have been proposed ...

Three karst springs in the folded Appalachians of Pennsylvaniawere monitored for stage, specific conductivity, and sediment concentration.
