Geophysical Exploration Techniques
o Geophysical Exploration: is an applied branch of
geophysics, which uses physical methods, such as
seismic….etc. at the surface of the Earth to measure
the physical properties of the subsurface, along with
the anomalies in those properties.

Geophysical Exploration Techniques
o Geophysical methods are divided into two types: Active and
Passive techniques
o Passive methods (Natural Sources): Incorporate measurements of
natural occurring fields or properties of the earth. Ex. SP, Magnetotelluric
(MT), Telluric, Gravity, Magnetic.
o Active Methods (Induced Sources) : A signal is injected into the
earth and then measure how the earth respond to the signal. Ex. DC.
Resistivity, Seismic Refraction, IP, EM,, GPR.
