Geoelectrical Studies:
It is the branch of Geophysics that address with rocks behavior and sediments in relation to electric current. The physical parameter controlled in this studies is resistivity and the final interpretation is based on the geological characteristics of the area in which geoelectric prospection methods are applied.
Electrical Tomography:
It is a DC method whose purpose is to determine the variation of the electrical resistivity of the subsoil according to depth and along a 2D profile. In the Dipole-Dipole the four electrodes move relative to a center but at the same time also move laterally whose objective is to see variations of resistivity in 2-D (X and Z).
Arrangements:
Dipole-Dipole, Polo-Dipole.
Applications:
Geotechnical, geological characterization, cavity detection, fractures, water table levels and determination of the different strata of the subsoil and their thicknesses up to 12.00 meters deep.
Vertical Electrical Explorations:
They allow information to be obtained in a 1D terrain by applying direct current pulses as a stimulus while recording the potential difference generated by the terrain as a response. This method allows to characterize the subsoil, detect underground layers, define the condition of the rocky base, know the geological distribution of the rocks and determine faults and fractures
Arrangements:
Wenner, Schlumberger.
Applications:
Geohydrology, Physical Earth System and Cathodic Protection.
