Electrical Resistivity Tomography

At Retro Geoenergy, we provide advanced Electrical Resistivity Tomography (ERT) services to deliver high-resolution imaging of the subsurface. ERT is a powerful geophysical technique that measures variations in the electrical resistivity of the ground, enabling accurate mapping of subsurface structures, groundwater resources, mineral deposits, and geotechnical conditions.

By using modern multi-electrode systems, 2D/3D inversion modeling, and robust field practices, we offer reliable data that supports exploration, environmental studies, geotechnical investigations, and hazard assessments.

Groundwater Exploration & Management

• Identification of aquifers, groundwater potential zones, and recharge areas.
• Mapping of saline water intrusion, contamination plumes, and over-extraction impacts.
• Monitoring of seasonal and long-term groundwater dynamics.

Mineral and Resource Exploration

• Mapping of ore bodies, coal seams, and shallow mineralized zones.
• Detection of lignite, bauxite, laterite, and metallic mineral deposits.
• Supporting pre-feasibility and feasibility studies with resistivity-based models.

Engineering & Geotechnical Investigations

• Subsurface imaging for foundation studies, tunneling, dams, and road projects.
• Detection of cavities, fractures, weak zones, and overburden thickness.
• Site characterization for large civil and infrastructure projects.

Environmental & Hazard Assessment

• Locating contaminated zones, landfill boundaries, and leachate plumes.
• Monitoring soil moisture and slope stability in landslide-prone areas.
• Assessing seawater intrusion in coastal aquifers.
