Exploration geophysics is the use of seismic, gravity, magnetic, electrical and electromagnetic, etc., methods in the search for oil, gas, minerals, water, etc., with the objective of economic exploitation. The Society of Exploration Geophysicists (seg.org (http://www.seg.org)) has the most recent update of the sciences and technologies of exploration geophysics (see also petroleum geology).
Geophysicists use a variety of methods, depending on the geological object they wish to visualize.
Geophysicists work in the field, which may be onshore or off, or else in the oil company's scientific and technical center.
As in geology, certain geophysicists seek to improve on existing techniques in data acquisition, and mathematical processing, as well as seeking to develop new techniques and methods.
Geophysicists study the structure and behaviour of the Earth, including oil and gas deposits, earthquakes, fault lines and volcanoes.
Turnover among geophysicists is generally low, but is higher among those in the exploration field because of their work places and conditions.
Geophysicists also develop advanced computer skills that are easily transferable to the IT industry and some leave to pursue opportunities that can offer them a higher salary.
