Borehole Logging
Borehole logging applies well-established geophysical techniques to the subsurface, permitting detailed characterization of in-situ lithological variations.
-
Electrical Resistivity
Electric current is passed into the ground to reveal subsurface resistivity variations caused by geological, hydro-geological and manmade variations.
-
Electromagnetic
Whether using Frequency Domain or Time Domain methods, an electromagnetic field is employed to induce Eddy currents into the ground.
-
Gravity
Subsurface density variations, detectable through gravitational acceleration measurements, can signal the presence of geotechnical hazards like cavities.
-
Ground Penetrating Radar (GPR)
By propagating an electromagnetic wave, in the radio frequency bandwidth, through the ground GPR can identify buried utilises and obstructions.
-
Magnetic
Buried ferrous materials cause localised variations in the Earth’s magnetic field and indicate the presence of ore bodies and buried man-made objects.
-
Multi Sensor Platforms
To improve survey productivity, certain geophysical techniques can be recorded simultaneously whilst mounted on a common platform.
-
Radiometric
The presence of naturally occurring radioactive isotopes such as Uranium, Potassium and Thorium serves as a reliable basis for characterising rock and soils
-
Seismic
The propagation of seismic elastic waves through the ground allows for the derivation of crucial subsurface structural properties.
