Earth resistivity topography (ERT)
Often used for analyzing soils for thickness or conductivity, most commonly in environmental investigations. Can also be done in large scale as an ore exploration or structural analysis method. In both large and small-scale work commonly done together with IP.
ERT reacts to natural conductivity variance (ores, water bearing structures) but can also be applied to man- made sources of conductivity variance, such as contamination.
A spread of electrodes is spread to the ground and connected to transmitter and receiver before measuring. Reachable depth of measurement depends on survey setup and ground conditions and is interconnected with resolution of results. Various survey configurations are applied and always designed based on the investigation target.
Please, see our resistivity equipment from equipment listing. If you can’t find desired geophysical or any other equipment from our selection, please let us know. We have excellent connections to rental agencies and pools. Our crew has comprehensive experience of various geophysical equipment.
Client will always receive quality assured raw data from the surveys. Additionally, we are able to the data processing and invert and model the results. Reporting to requested level as well as orientation of the client to the survey results will be done as requested.
The final product of ERT method is usually 2D speudosections or inversion results or 3D voxel models of the target.
