We conduct

Transient Electromagnetic Method (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: First meters to 500–600 m
Productivity: Up to 24 soundings / day
Team size: 10 people

■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.

TEM acquisition — operator preparing the transmitter and batteries in the field — TEM — acquisition

We conduct

Magnetotelluric surveys (MT)

Geophysical method that measures Earth's natural electromagnetic fields.

Depth range: 300–5000 m
Team size: 4 people

■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.
