Everything about Exploration Geophysics totally explained
Exploration geophysics is the applied branch of
geophysics which uses surface methods to probe or detect properties of the subsurface
Earth.
Exploration geophysics is the practical application of
physical methods (such as seismic, gravitational, magnetic, electrical and electromagnetic) to remotely sense underground anomalies. The conventional application to this science is searching for
mineral and
petroleum deposits. However it can also be used in other areas such as monitoring environmental impact, imaging subsurface
archaeological sites,
civil engineering site investigations and interplanetary imaging. In addition to universities and technical institutes such as the
Colorado School of Mines,
University of British Columbia
,
Curtin University
, professional societies such as the
Society of Exploration Geophysicists (SEG) (
seg.org
) and the
CSEG
and
ASEG
have the most recent updates of the sciences and technologies of exploration geophysics.
Exploration Geophysics careers are in such widely varying industries as
oil & gas exploration,
mining, environmental studies, planetary physics and even archaeology.
The following techniques are used:
- Seismic methods, such as reflection seismology, seismic refraction and seismic tomography.
- Magnetotellurics
- Scientific drilling
- Transient electromagnetic (EM) (see, for example Geonics instruments
)
- Radio frequency electromagnetic propagation (for example, ground penetrating radar)
- Electrical techniques, including Electrical resistivity tomography and induced polarization
- Magnetic techniques, including aeromagnetic surveys and magnetometers.
- Gravity and Gravity Gradiometry
- Geodesy
- Remote sensing
