Geophysics is the study of the subsurface of the earth based on the differences in its physical properties.

Each type of rock and soil has unique physical properties. Geophysical survey techniques include 2D, Gravity, Magnetic, Transient Electromagnetic (TEM), Very Low Frequency Electromagnetic (VLF), and Radiometric Seismic Methods, which are used to detect differences in the physical properties of subsurface materials.

Geophysical surveys are used in the following geological surveys:

Underground Water Study

• Underground Water Exploration
• Underground Water Pollution

Drill-hole geophysical logging

• Using resistance, gamma, calliper, and self-potential probes
• Identify the drill hole lithology and detect cracks.
• Validate the lake's design in order to collect water licences.

Mineral Exploration

• Identify the presence of minerals.
• Identify the geological structure that has a relationship with mineralization.

Geological Engineering Study

• The thickness of the loaded soil and the depth of the bedrock
• The existence of geological structures such as unconformities, faults, and joints
• Geological disasters such as crevasses, sinkholes, and caves.

Surrounding Area Study

• Saltwater Intrusion
• Solid waste disposal site
