Towed Transient Electromagnetic Near Subsurface Surveys

Service Name

tTEM survey overlay on aerial photo of a Central Alberta agricultural location. Rainbow tracks trace data lines across fields with 50m distance markers. Blue "Well" pin marks existing wellsites. Survey results show efficient subsurface mapping for aquifers & geo-features.

tTEM Resistivity Survey

This tTEM survey image shows a 3D subsurface resistivity model (1-1000 ohm-m scale, blue low to purple high). Layered formations with conductive (blue/cyan) zones suggesting aquifers/clay, and resistive (yellow/green) areas.

tTEM Survey Equipment

The tTEM 3x2 transmitter array and accompanying receiver sleds are towed with a UTV following preplanned GPS designated survey paths.
