Electrical Resistivity Survey

Electrical Resistivity Survey

Electrical Resistivity Surveys are geophysical investigation methods used for groundwater exploration, geological mapping, environmental studies, and subsurface investigations.

These surveys measure subsurface resistivity variations to identify aquifers, fractures, geological formations, and underground anomalies with reliable accuracy.

Daily Coverage CapacitySurvey Coverage: 2–8 Line KM/day

Key Deliverables

• Groundwater/Geological Target Mapping

• Subsurface Lithological Interpretation

• Resistivity Profiles & Sections

• 2D/3D Resistivity Models

Damage Mapping for Insurance

Accuracy & Data Quality

  • Electrical resistivity surveys provide dependable depth and layer estimation, with accuracy influenced by site conditions and survey design.

    • Depth accuracy: ±5–10%
    • Clear differentiation between water-bearing and dry formations
    • Ability to detect multiple subsurface layers
    • Accuracy improves with optimized electrode spacing and data interpretation

Key Applications

Electrical Resistivity Survey is widely used across multiple industries:

Groundwater Exploration

Locate aquifers, estimate depth, and identify high-yield zones.

Soil & Geotechnical Investigation

Analyze soil layering and detect weak or problematic zones.

Geological Mapping

Identify rock formations, fractures, and subsurface variations.

Environmental Studies

Detect contamination zones and subsurface changes.

Make informed decisions before drilling
