Electromagnetic Survey

At Retro Geoenergy, we provide advanced Electromagnetic (EM) Survey Services for mapping subsurface conductivity variations with high precision. Electromagnetic methods are powerful tools for investigating groundwater resources, mineral exploration, geotechnical assessments, and environmental studies.

By transmitting controlled electromagnetic fields into the ground and measuring the secondary fields induced by subsurface conductors, EM surveys allow rapid, non-invasive, and detailed characterization of geological structures, ore bodies, and hydrogeological systems.

Mineral Exploration

• Locating and delineating sulphide ore deposits, graphite, and conductive mineral zones.
• Mapping alteration zones and faults associated with mineralization.

Groundwater & Hydrogeology

• Identifying aquifers, fracture zones, and groundwater pathways.
• Delineating saline water intrusion and water table variations.

Geotechnical & Engineering Investigations

• Mapping depth to bedrock, weathered zones, and structural discontinuities.
• Site assessments for dams, tunnels, roads, and foundations.

Environmental & Hazard Studies

• Detecting contaminant plumes, leachate migration, and buried waste.
• Assessing soil conductivity changes due to pollution or landfill sites.

Oil, Gas & Coal Exploration

• Identifying conductive zones associated with hydrocarbons, coal seams, and lignite deposits.
• Supporting integrated seismic and resistivity surveys.
