Geoelettrical Methods and Application

This course contains the use of artificial intelligence.Geoelectrical investigation is a geophysical technique used to determine the subsurface resistivity distribution by measuring the electrical response of the ground to an applied current. It is widely applied in groundwater exploration, environmental studies, mineral prospecting, and engineering site investigations. The main target of geoelectrical surveys is to identify variations in lithology, detect aquifers, locate contamination plumes, or map fracture zones and weathered layers.

Field data are typically collected using electrode configurations such as Wenner, Schlumberger, or Dipole-Dipole arrays, depending on the investigation depth and resolution required. The apparent resistivity values obtained are processed and interpreted using specialized software tools. Commonly used software includes Res2DInv and Res3DInv for two- and three-dimensional inversion of resistivity data, IPI2Win for quick one-dimensional interpretation, and AGI EarthImager for advanced modeling and visualization. These programs perform inversion algorithms that convert raw apparent resistivity measurements into true subsurface resistivity models, enabling clear delineation of geological structures.

By integrating geoelectrical data with other geophysical or geological information, investigators can enhance subsurface characterization accuracy. Ultimately, geoelectrical methods and modern inversion software provide a cost-effective, non-destructive, and reliable approach to understanding subsurface conditions for hydrogeological and engineering applications.
