Geophysical Services
Geophysical Services Overview
Geophysical services encompass the collection, interpretation, and mapping of the physical properties of Earth’s surface and subsurface regions. These services are employed across diverse industries, including mining, geology, engineering, environmental studies.
Various geophysical methods are applied to investigate the mineral, geological, and structural composition of the Earth, providing vital information for decision-making processes related to resource extraction, infrastructure development, and environmental management.
Common Methods and Applications
Some of the key geophysical methods and their respective applications include:
- Resistivity and IP Surveys – Measure electrical properties of subsurface rocks, suitable for mineral, geothermal, and groundwater exploration
- Gravity Surveys – Detect changes in the Earth’s gravitational field due to variations in density, revealing faults, voids, and subsurface structure
- Magnetics (Mag) – Identify anomalies in the Earth’s magnetic field, useful for finding mineral-bearing ore bodies and subsurface structure
- Seismic Surveys – Generate images of the Earth’s subsurface using seismic refraction or reflection, ideal for planning exploration and development
- Ground Penetrating Radar (GPR) – Image the subsurface by detecting reflected signals from the Earth’s surface, applicable for prospecting, borehole structure mapping, etc.
- Time Domain Electromagnetics (TDEM) – Determine subsurface electrical properties while also sensitive to magnetic properties, commonly used for mineral exploration
Benefits and Usage
- Improving efficiency during exploration and development phases.
- Assisting in optimizing field development plans.
- Supporting environmental studies and regulatory compliance efforts.
- Helping to locate underground utilities, storage tanks, and other assets.
