Electrical Survey

Electrical Survey:

The survey is meant for studying horizontal and vertical discontinuities in the electrical properties of the ground upto several hundred meters. The survey utilizes direct currents or low frequency alternating currents to investigate the electrical properties (resistivity) of the subsurface. A resistivity contrast between the target and the background geology must exist.


  • water table mapping
  • soil or rock lithology
  • fracture location
  • mineral exploration
  • mapping clay layers or sand deposits

Time Domain Electromagnetic Survey


  • ISR has started geophysical surveys for Geothermal Energy in Gujarat state. ISR has pioneered a technique of 3D MT imaging of crust. Geological faults and crustal structure have been mapped in Kachchh.
  • ISR is carrying out Multiparametric Geophysical and Geochemical studies in Kachchh for earthquake prediction research.
  • ISR has upgraded Gujarat State Seismic Network from 19 online seismic stations to 40.
