Product Description
Transient electromagnetic called Time-Domain Electromagnetic (TDEM), is the basic method applied for locating the massive sulphides, problems associated with geological structures, partly in oil-and-gas prospecting (specially to corroborate seismic data). Two variants are in common use: Stationary source and moving source. In stationary source TDEM profiling surveys a large loop is laid parallel to the strike of the formations/ targets and the Receiver is moved along the traverses to record the three components of the secondary induced magnetic field when the strong currents passing in the loop are switched off momentarily. In TDEM sounding the receiver records the transient decaying secondary magnetic field at the centre of the loop coaxially. Sophisticated software for processing profiling and sounding data is commercially available. In moving source both the transmitter and receiver are moving along the traverses.
Why use Transient Electromagnetics (TEM)?
Non-destructive, inductive method, of mapping conductivity/resistivity
Simple field set-up
Extremely responsive to, and can differentiate between, conductive bodies
Groundwater, mineral deposits and environmental change
Suitable for search, mapping and monitoring projects
Rapid measurement cycles
Depths of hundreds of metres can be investigated in minutes and whilst othersurvey methods would still be setting up
Applications of Time-Domain Transient Electromagnetics (TDEM/TEM) Equipment Geophysical Resistivity Sounding Instrument for Unerground Exploration
1. Detect aquifers, fault aquifers, coal seam structures and subsidence at ground level
2. Downhole detection of water storage structures in and around the mining area and in front of the driving head
3. To detect the burial depth and occurrence of good conducting ore body, and to detect ore accumulation structure
4. Detection of old kiln and its water content
5. Engineering exploration and environmental exploration
6. Oil and gas field exploration
