Global Top 6 Geophysical Equipment and Services Companies [2023]

Published on 08th May 2023

Geophysical companies play a key role in exploring and developing natural resources. Apart from companies with expertise in geophysical techniques, the demand is also increasing for companies with seismic surveying and seismic testing capabilities.  


Let’s try to understand the geophysical method and survey in detail before moving on to the list of top market players.


What is a Geophysical Method?


A geophysical method measures the physical properties of materials to gain information about the Earth’s surface and subsurface, including subsurface conditions and subsurface formations. Geophysical methods are also used in hydrogeology for groundwater exploration and contamination studies.


Here are the most common geophysical methods:


  • Electrical method
  • Electromagnetic method
  • Geothermal method
  • Gravity method
  • Magnetic method
  • Radiometric method
  • Seismic method


Examples of geophysical methods include ground-penetrating radar (GPR) and seismic reflection and refraction. Geophysical devices like magnetometers and seismographs are used in seismic investigations for detecting earthquakes and surveying the Earth’s crust.


Another common method of acquiring geophysical data is “borehole logging (borehole geophysics),” which involves analyzing geophysical data collected within boreholes, test holes, or wells.


What is a Geophysical Survey?


A geophysical survey refers to collecting geophysical data systematically for spatial studies.


For instance, airborne geophysical surveying is a process used to measure the variation of many key physical or geochemical parameters of the Earth, such as conductivity, magnetic susceptibility, radioactive element concentration, and rock density.


Compared to ground surveys, aerial geophysical surveys are ideal for cost-effective, rapid scanning of target areas.


Based on revenue, the top geophysical equipment and services industry players include Schlumberger Ltd., PGS ASA, CGG SA, and TGS ASA.

Wrapping Up


Rising energy requirements are supporting strong investments in geophysical investigations and seismic operations.


Consequently, there is a growing demand for integrated geophysical services involving diverse activities, such as locating and measuring the extent of subsurface resources (oil, gas, minerals, etc.) and conducting diverse surveys (gravity surveys, magnetic surveys, seismic surveys, etc.)


A subsurface investigation is carried out to know more about the geometry of the soil, rock, and water beneath the surface. For example, mapping the subsurface plays a key role in the O&G industry to mitigate hazards and discover new areas for detailed exploration.


Similarly, seismic exploration companies not only help with seismic data collection for petroleum exploration but also provide related products and services like project management (for conducting feasibility studies, providing onshore support, etc.).


For example, a geophone is a seismic instrument that transforms ground vibrations generated by seismic waves into electrical impulses.


The global seismic survey market is also witnessing steady growth due to increasing exploration activities driven by the high energy demand across regions.


For instance, shale explorations along with offshore shallow water and deepwater exploration are leading to the development of new seismic projects.


Tackling today’s geophysical and seismic challenges requires specialized knowledge and proven experience besides collaborative innovation.


Geophysical and seismic companies provide industry experience and technological expertise to minimize uncertainty and maximize value in the quest for natural resources.
