GEOPHYSICIST
Geophysics is a very broad subject. The majority of the students studying geophysics actually concentrate on traditional pure geophysics/global geophysics/solid earth. geophysics. Geophysical theories: gravity, magnetics, seismology, geodynamics, and tectonics, etc. all come under the Geophysicist. The study is generally in a relatively global scope or the impact areas are substantial parts of the earth. On the other hand, applied geophysics, with its applications for economic benefits, concentrates more on shallower parts of the earth, mostly confined in the crust. Considering the money involved, oil and gas exploration occupied probably 80% or more of the applied geophysics; the rest is mainly for the mining industry. Near surface geophysics, or environmental & engineering geophysics, is only a small fraction of applied geophysics. After you get a bachelor degree in geophysics, if you want a geophysics related job with big bucks, most likely you'll go for oil & gas exploration.
You can be in the field crew or do some simple data processing jobs. You'll be a part of work flow, working like a robot, doing same kind of tasks repeatedly everyday. However, if you want to do something more versatile and challenging, or open your own company and be your own boss in the near future, near-surface geophysics is the best choice. For near surface geophysics, some methods are less commonly used than other methods. Gravity is probably the least used method. Self potential, induced polarization and magnetic methods are the next least used methods, although they are frequently used in the mining industry.
Role:
- Demonstrate excellent 3D and 2D interpretation skills in time and depth under a variety of exploration and development scenarios, with a sound knowledge of attribute analysis, siesmic modelling, impedance inversion, seismic processing and well planning.
- Performing the analysis of all seismic ata an its incorporation into 3D geological models of operated fields with the objective of providing 3D models for use in the reservoir management of operated fields.

The magnetic method is used a lot in archaeology applications, but there is really not much money in it compared to those spent in engineering and environmental applications. In the other hand, budgets for near surface geophysics are mostly used on seismic, electromagnetic, ground penetrating radar and direct current resistivity methods. Good understandings and hands-on experiences on these methods, including survey designs, data collections, data processing and report generating, will give you a very good start for your career in near-surface geophysics.You must be familiar with computer languages such as Matlab, C and Fortran and you think you don't have problems with computers. When you get into the industry, you will find that you need to learn and get yourself familiar with a lot of commercially available programs.
