Electrical resistivity depends directly on porosity, pore fluid resistivity, and saturation. When pore fluids in the rocks are replaced by oil or gas, most physical properties of the rocks are modified. Electrical resistivity is most affected. Rocks

In the application of electrical methods in areas of complex geology, two levels of complexity can be recognized. At lower levels of complexity, a fundamental dependence of resistivity on depth can be recognized. In such cases, the profile of resisti

The term time‐domain electromagnetic sounding can stand for any of a variety of electrical exploration methods in which the transient response of the Earth to a pulse‐like magnetic field is measured. Such methods have been described in the geophy

In the bipole‐dipole mapping method, current field is set up by the use of a bipole current source. The current field is then studied by making measurements of electric field intensity with dipole receivers at many locations around the bipole sourc

Efforts to determine the conductivity in the Earth at lithospheric and mantle depths are inhibited by the effect of conductive rocks and sea water at the surface on the behavior of electromagnetic fields. Experience has suggested that the surface eff

Drilling and geophysical logging data for a 1,262 m-deep bore hole in the area inferred to overlie the magma reservoir of Kilauea Volcano, Hawaii, support earlier interpretations based on surface geophysical surveys that a zone of brackish or saline
