What is Applied Geophysics

Applied geophysics is an interdisciplinary field which utilises the basic principles of physics to interpret subsurface phenomena. Applied geophysics mainly focuses on gathering and interpreting of data obtained on subsurface phenomena. These data are interpreted and the results are used for various practical purposes like gas and oil exploration, groundwater exploration, mineral exploration, geothermal exploration, archaeological interest and so on. This branch of geology is often referred to as "quantitative geology". An easier definition claims geophysics to be a course where pupils learn physics of the earth and its atmosphere. This includes studying oceanography, seismology, geomagnetism and volcanology.


Since humans cannot locate the mineral deposits under the surface with simple methods, we need fields like geophysics which helps in locating underground resources. Thanks to the rapid development in recent years, all geoscientists including geophysicists are in high demand. The energy industry is facing the greatest challenge in this respect. Hence, they are in need of efficient geophysicists.


Due to the importance of this course, applied geophysics is offered as a specialisation in a number of colleges across India. Applied geophysics is taught as a course which is a part of the wider course of geology. So the colleges also provide degrees with specialisation in applied geophysics. In this article, we shall discuss in detail the course of applied geophysics including the available courses, the job profiles and upcoming trends in the field of geophysics.


Degrees and Levels of Applied Geophysics

Postgraduate level (M. Tech): Candidates who have completed B. Sc in Physics or geology can opt for a 2-year M. Tech course in applied geophysics. 

Integrated B. Tech + M. Sc. Tech course: IIT (ISM) Dhanbad offers this 5 years’ course. It gives off an aspirant the undergraduate degree. 

Dual degree (M. Sc- PhD): This dual degree is provided to aspirants who already have a bachelor degree in applied geophysics or other relevant topics. The dual degree programme is available in the IITs across the country. 


Applied Geophysics- Minimum and Maximum Duration

M.Tech in applied geophysics takes up a minimum duration of 2 years or 24 months. During this time the candidates are required to cover all the stipulated credits without backlog. For candidates who fail to clear backlogs universities often provide extended time periods in which they can clear the backlogs. In special cases, the time span is 3 to 4 years or 36 to 48 months at the most. The exact extent of elongation depends on the specific university.

The exact fee of the courses depends on the college from which the course will be pursued. The fee can range from Rs.60, 000- Rs.10, 00, 000.  Banaras Hindu University (BHU) has a course fee of Rs.60, 000 for 2 years. The esteemed B. R. Ambedkar National Institute of Technology has a course fee of Rs.10, 00,000 for the entire course.

Scope of Applied Geophysics in India and Abroad

Applied geophysics is one of the most high-demand fields in the world. In developing and developed countries alike the value of mineral resources is undeniable. Even when global trends are shifting to renewable resources the importance of minerals has not depreciated. While countries rich in natural minerals like Canada, Russia, Brazil and Venezuela have high demands of geophysicists.

India is one of the countries rich in minerals. With the advancement of time and technology, India is also moving toward being a developed country from a developing country. Thus the industrialisation is also on the rise which means high demand for fuels and natural resources. The need for applying physics to interpret the subsurface resources is also on the rise.

Required Skillset for Applied Geophysics

Observation: Observation is an important skill that is very useful for the fields of applied geophysics. Individuals are expected to be very careful and observe accurate data when collecting data and mapping areas from interesting regions. Any error in the observation of data can lead to massive damages.

Analysis: One of the biggest assets in the field of applied geophysics is the analytical skill of the candidate. What helps in the segregation of candidates into various levels of efficacy are the analytical skills possessed by the candidates. The data collected must be analysed by you without any mistakes and results must be accurate.

Teamwork: As a fresher, your initial jobs will require you to work as a part of a team. It is essential for all individuals to be well in tune with the members of the team. This will not only help in building rapport but will also help in improving the efficacy of the team and ultimately benefit the company. One must possess the ability to work as a part of the team without compromising on individual responsibilities. Working as a team can also help in improving leadership qualities and sharpen communication skills.

Instrument handling: Geophysics is a subject in which application of the theories is very much dependent on instruments which are used for the studies. To effectively observe data is imperative that the candidate must be familiar with the instruments in use. Candidates must possess adequate knowledge about working of the instrument and must know how to operate and collect data from these instruments.
