Geophysical Exploration Methods

The Gehrig, Inc. team employs a wide variety of geophysical methods to answer client questions associated with exploration, engineering, and environmental projects. All geophysical methods utilize instruments to measure contrasts in the physical properties of subsurface materials. Data are processed using state of the art software then the results are interpreted by our experienced geophysics staff.

Geophysical Exploration Methods

Gehrig, Inc. has a high degree of flexibility regarding choice of geophysical method(s) to answer your question due to our large investment in geophysical instruments, software and computing technology, and training. This is relevant to your project because no single method can be utilized to answer every question. Our large toolbox allows us to select the right geophysical method, or combination of methods, to answer your specific question. We specialize in integrating the data from multiple geophysical methods to leverage their synergies and provide a robust deliverable with the greatest possible value for you.

The Gehrig, Inc. team regularly uses the following methods to assist our clients with a diverse array of exploration, engineering, and environmental projects:

  • Seismic – refraction, reflection, MASW, cross-hole, downhole
  • Geo-electrical – resistivity, Induced Polarization (IP), Self-Potential (SP)
  • Electromagnetic (EM)
  • Ground Penetrating Radar (GPR)
  • Seismoelectric (SE)
  • Magnetic
  • Gravity
  • Borehole Geophysics
