Our Methods

Geophysical survey methods

GGEO uses primarily four geophysical survey methods to provide solutions to multiple geophysical subsurface problems. Which method to chose depends on a project’s objective, budget & geological condition. However, no matter which method you choose, they are all non destructive. 

Resistivity and Induced Polarization

Resistivity/IP is a geo-electrical method that can measure the ground’s resistivity and chargeability properties. Typical applications are groundwater exploration, environmental research and mineral prospecting. Guideline Geo offers solutions that range from cost-effective 1D measurements to advanced 3D imaging.

Ground Penetrating Radar

Ground penetrating radar – a geophysical method that operates by transmitting electromagnetic waves from an antenna and reflects off layers and objects hidden in the ground. These reflections are collected as data which generates a picture of the subsurface.

As manufacturers of the broadest GPR range in the world, GGEO MALÅ offers solutions for multiple geology applications, such as climate research, underground utility locating, archaeological excavations, infrastructure and construction to mention just a few.


Transient electromagnetics (TEM) is an extremely effective method in determining electrical conductivity of the subsurface at depths from a few meters down to several hundred meters. Applications include groundwater and mineral exploration and environmental investigations. ABEM has pioneered the advancement of the TEM technology resulting in solutions capable of accurately resolving subtle changes in geology in fine detail with excellent depth penetration.


Near-surface seismics is a method that utilizes a vibration source to measure propagation of elastic waves. The results will show the mechanical properties of the ground. Common applications are soil stability, rock quality and depth to bedrock. ABEM Terraloc Pro is a seismograph that can be used for seismic surveys ranging from simple refraction measurements to complex 3D cross-borehole tomography.
