Earth Scientists, Geoscientists, Geophysicists, Geologists study the earth, including its composition, structure and other physical aspects for oil discovery and production and use complex equipment to collect seismic data.  They are usually linked to the actual discovery of oil and the identification of possible oil deposits (areas underground where oil is trapped), and make the decision on where the location of drilling will occur.

An Earth Scientist’s main responsibilities include:

• Controlling the quality of the seismic data collected
• Interpreting seismic data to create maps of the build up of hydrocarbons (crude oil and natural gas).
• Examining the physical properties of rocks, as well as gathering and evaluating well data to build reservoir models.
