With today's technology, it is no longer necessary to excavate or drill boreholes in the ground to find out what is present below the surface.
Sophisticated investigation techniques using electromagnetic and seismic waves can produce geological 'data maps'. This can potentially reveal reservoirs of water, gas or oil.
NGI's state-of-the-art expertise
- marine EM (electromagnetics) technology, equipment and analytical tools

- seismic modelling of fractured rock
- geophysical laboratory measurements, including CT (computer tomography)
Services related to geophysics
NGI's expertise in geophysics is focused on various methods and equipment for mapping offshore reservoirs and detecting oil and gas. With comprehensive scientific expertise, not only in geophysics, but also in instrumentation and equipment development, geology, geo-mechanics, laboratory testing and numerical modelling, we have a unique starting point from which to realise ideas.
New concepts are developed by means of modelling, analysis, testing of new sensor technology, geophysical laboratory work, design, assembly of prototypes and field trial testing.
Research and development
The main focus is on research and development on seismic and electromagnetic methods, with a bandwidth from DC to several gigahertz. We are constantly improving our methods and solutions and have developed a more efficient data acquisition system, higher precision and more refined and reliable interpretation of data, which in turn saves the industry significant expense.
An improved version of the prototype for generating shear waves down into reservoirs from the seafloor, the next generation marine EM technology, and new targets for airborne EM are current projects.
New concepts and instrumentation have led to the registration of many new patents, and several spin-off companies have been established on the basis of NGI's research and development results.
