Geophysical methods

Geophysical investigation techniques help us to identify geological, geotechnical and hydrogeological parameters from the surface to more than 2000 meters below the ground based on measurements in boreholes, along profiles and on surfaces. By using geophysical surface methods we can estimate the physical conditions of the earth or seabed in 2D or 3D models and link drillings and cone penetration test (CPT) data, for example, to a consistent geological model.

Our primary fields of expertise are:

  • Seismic profiling, including reflection and refraction surveys and surface wave seismics
  • Marine studies
  • Logging of boreholes and Vertical Seismic Profiling (VSP)
  • Transient electromagnetic sounding (TEM) studies
  • CVES (Continuous Vertical Electrical Sounding ) or Multi-electrode Profiling (MEP) studies
  • Magnetic Resonance Sounding (MRS)
  • Airborne geophysical methods – SkyTEM and Helicopter electromagnetic (HEM) surveys
  • Georadar surveys
  • Geodesy
  • Metal detector/UXO surveys
  • Other fields of expertise such as gravimetry
  • Our geophysical studies are based on the analysis and interpretation of field measurements. The quality of the field measurements is critical to the reliability of the results.

Educated and experienced consultants

At Ramboll we have both highly educated and experienced consultants and a comprehensive range of state-of-the-art tools and instruments at our disposal. We also employ qualified technicians who are responsible for the development, calibration and maintenance of our equipment.

We carry out all kinds of projects from minor jobs for water supply companies to major marine feasibility studies for natural gas pipelines, bridges and wind farms. We also apply our broad knowledge of geophysical methods to a wide range of highly specialised jobs such as oil and gas exploration, mining, geothermal power and CO2 storage.

Relevant projects

Ramboll investigates the feasibility of groundwater aquifers for desalinated and fresh water storage.

Groundwater Exploration in the Emirate of Dubai

Ramboll’s experience in the successful completion of the feasibility study at Liwa Oasis contributed to Dubai Electricity and Water Authority (DEWA) appointing Ramboll to perform a groundwater survey, using non-intrusive methods, to check and assess the potentiality of Dubai aquifers to store and naturally desalinate the sea water.

Geophysical Borehole Logging

As a geophysical consultant for Svensk Kärnbränslehantering AB (SKB), Ramboll has carried out geophysical borehole logging as part of the site investigations for a deep storage facility for radioactive waste.

Assessing the Environmental Impact of Norway's Largest Dredging Project

Norway's largest dredging project to date is underway, enabling large 'Panamax' ships of 70,000 deadweight tonnes to enter the port of Fredrikstad by 2015. The Norwegian Coastal Administration (NCA) has asked Ramboll to conduct a comprehensive evaluation of the impact that the work will have on local biodiversity.

Major pollution abatement in Algeria

The Algerian Ministry of Environment has launched a major programme for pollution abatement of the River Chlef. The 800 km long Chlef is the country’s most important river. Around four million people live along the river banks, which also accommodate a large number of heavily polluting industries.
