A geophysicist/field seismologist studies physical aspects of the earth and uses complex equipment to collect data on earthquakes and seismic waves, which move through and around the earth.
Their main responsibilities are controlling the quality of the seismic data collected and interpreting it in order to create maps of the build up of hydrocarbons. They also examine the physical properties of rocks, as well as gathering and evaluating well data in order to build reservoir models.
Job descriptions and job titles vary according to the area of employment. The role generally involves undertaking seismic exploration and producing controlled source seismic data for an oil company or consultancy. However, geophysicists/field seismologists may also be involved in providing environmental consultancy, e.g. investigation of landfill sites, using geophysical techniques, or working within a research institute to investigate seismological structures and provide seismological information to the public and government.
