Geophysical Prospecting for Groundwater,) when the ground is energized by another two current electrodes. Here, the ratio of voltage and current multiplied by geoelectric constant provides the apparent resistivity. Interpretation with curve-matching techniques provides the true resistivities and respective thicknesses. Different range ofTAP 发表于 2025-3-25 15:18:36
Borehole Geology and Well Logging,r the detection of porous and permeable freshwater-saturated zones against low-resistivity adjacent shale and clay beds and estimation of their thicknesses. Porosity can also be calculated from this log. Natural gamma log is used to detect clay or shale content. Neutron, sonic and density logging arharpsichord 发表于 2025-3-25 16:31:04
