Geophysical Services
Fieldwork in action - team, equipment, and landscapes we work in
We conduct:
Transient Electromagnetic Method (TEM)
TEM – transient electromagnetic method operating in the near-field zone, provides detailed distribution of electrical resistivity with a focus on conductors (brine, clays, metals)
Depth range: from the near-surface (first meters) to 500–600 meters
Survey productivity: up to 24 soundings per day

Key aspects:
  • High sensitivity to conductive objects.
  • High vertical resolution in the upper part of the section.
  • Robust against external electromagnetic noise.
  • Fast and mobile field operations.
  • Team size: 10 people.

We conduct:
Magnetotelluric surveys (MT)
MT – geophysical method that measures Earth’s natural electromagnetic fields.
Depth range: 300-5000 meters
Survey productivity: 5 soundings per day

Key aspects:
  • Maps resistivity distribution down to 5 km depth.
  • No transmitter required – fully passive method.
  • Effective in high-resistivity environments (granites, carbonates, crystalline shields).
  • Suitable for 3D resistivity imaging.
  • Team size: 4 people.
