A geophysical survey is a scientific method of analyzing the subsurface of the earth using physical measurements such as magnetism, gravity, seismic waves, or electrical currents. Geophysical surveys are typically used to locate and map underground structures, geological formations, or natural resources such as oil, gas, or minerals.
Geophysical surveys involve the use of specialized instruments and data collection techniques to capture and analyze physical measurements of the earth's subsurface. Several geophysical methods may be used to collect information about the subsurface, and the selection of the method will depend on the objectives of the survey and the characteristics of the terrain.
Seismic surveys are among the primary methods used for geophysical investigation. They utilize sound waves to map subsurface structures and estimate underground rock formations, mineral deposits, or hydrocarbon reserves. Another important technique is electromagnetic or conductivity surveying, which maps the electrical conductivity of the earth's subsurface.
Geophysical surveys are widely used in different industries including mining, petroleum, construction, and civil engineering to obtain a better understanding of subsurface conditions. Geophysical survey results can provide information about soil type, rock strata, faults, underground water flows, and any other characteristics of the subsurface.
In summary, geophysical surveying plays a critical role in understanding the earth's subsurface. The data gathered from geophysical surveys can help decision-makers in various industries to better plan, design, and execute projects related to infrastructure, energy production, and natural resource exploration.
