Geophysics is a discipline of geosciences concerned with the use of mathematics, physics, programming, and modeling to study the physical processes and properties of the Earth and its surrounding space environment. Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards, and environmental protection.
A geophysicist uses methods such as seismic, gravity, and magnetism to describe the subsurface and the earth's interior. Geophysical methods were developed for remote exploration of the solid Earth and the ocean.
Exploration geophysics is an applied branch of geophysics and economic geology, which uses distinct methods to measure the physical properties of the subsurface, along with the anomalies in those properties.
It is most often used to detect or infer the presence and position of economically useful geological deposits, such as minerals, fossil fuels, and other hydrocarbons, geothermal reservoirs, and groundwater reservoirs.
In exploration, geophysical survey data can be used to analyze potential petroleum reservoirs and mineral deposits, locate groundwater, find archaeological relics, determine the thickness of glaciers and soils, and assess sites for environmental remediation.
Seismic reflection and refraction techniques are the most widely used geophysical techniques in hydrocarbon exploration. They are used to map the subsurface and its structure to allocate potential hydrocarbon accumulations.
This effectively provides a seismic image of the subsurface for geologists and geophysicists to determine and understand the petroleum geology of the area.
