Geophysicists are majorly concerned with the physical processes of the Earth. They tend to be employed commonly by oil and gas companies, as well as environmental agencies. Geophysicists basically combine the sciences of geology and physics in order to locate resources like gas and oil, and predict natural disasters like earthquakes.
Paul Favret mentions that these professionals commonly employ techniques and principles of geology, physics, chemistry, mathematics, engineering, and certain other scientific disciplines to perform tests and determine the composition and structure of the earth.
Paul Favret briefly underlines the multiple types of exploration geophysicists
Geophysicist basically studies the interior of the earth by measuring responses to electromagnetic and seismic waves. They also study magnetic and electric fields and gravity. The findings of these professionals help them to gain a better understanding of what is below the ground, also called the subsurface. Exploration geophysicists commonly use this understanding to look for deposits of valuable minerals and petroleum. At times referred to as geophysical prospectors as well, these professionals use seismic techniques to competently look for possible oil and gas deposits. They also measure and chart the sound waves created by explosions.
The information obtained by exploration geophysicists from their tests and equipment readings allows them to competently determine the patterns and types of rocks beneath the surface. Readings taken from devices that measure magnetic focuses also assist geophysicists in finding out what is under the ground and sea. Exploration geophysicists are commonly employed by gas and oil companies to identify, analyze and assess the suitability of mining sites. They may even provide advice and recommendations on safety, environmental and political issues.
Exploration geophysicists can be of multiple types, such as:
- Energy exploration geophysicists: These professionals focus on studying information about the geological structure, rock makeup, minerals, and sediments. They determine where oil and gas accumulations are most likely to occur when searching for hydrocarbons. To find sources of geothermal energy, such professionals may search for areas with higher underground temperatures. Energy exploration geophysicists not only data from seismic work, but also conducts magnetic, satellite, or gravity surveys.
- Mineral exploration geophysicists: These geophysicists are responsible for searching for deposits using electrical and electromagnetic techniques. They may use seismic data to understand the geological structure in case they are working on the exploration of minerals dissolved in groundwater.
- Environmental geophysicists: These professionals are primarily responsible for gauging groundwater quality and assessing hazards. They efficiently collect and process diverse data. Environmental geophysicists commonly use electromagnetic, electrical, and seismic techniques for their job, along with ground-penetrating radar.
- Reservoir geophysicists: These professionals are meant to develop oil and gas projects. Reservoir geophysicists develop hydrocarbon properties or carbon sequestration projects. They monitor the distribution of fluids under the surface from above the ground and commonly use seismic electrical, and other techniques. Reservoir geophysicists generally work closely with geologists and petroleum engineers.
Paul Favret mentions that to become a geophysicist, one must study the physical aspects of the earth by using a variety of methods, including gravity, magnetic, electrical, and seismic. Collecting data on seismic waves would especially be helpful in creating a picture of what lies below the earth’s surface.
