There are many methods and types of instruments used in geophysical surveys. Technologies used for geophysical surveys include: Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography. Seismoelectrical method; Geodesy and gravity techniques, including gravimetry and gravity gradiometry. Magnetic techniques, including aeromagnetic surveys and magnetometers.
