Exploration geophysics is an applied branch of geophysics, which deals with the physical methods like seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the differences in those properties. Geophysical methods of exploration are means to collect geophysical data that can be used to prospect directly for economic minerals.

Geophysical methods for oil and gas exploration and mineral prospecting include almost all the major geophysical methods ever invented, oil and gas exploration is dominated by seismic reflection method, in both land and marine settings. Geophysical exploration may be used with advantage to detect margins between different elements of the subsoil as these procedures are based on the fact that the gravitational, magnetic, electrical, radioactive or elastic properties of the different elements of the subsoil may be different.
