Geophysical TEM Transient Electromagnetic For Underground Water Resistivity Magnetometer Device

Geophysical TEM Transient Electromagnetic For Underground Water Resistivity Magnetometer Device




The WTEM (Wireline Transient Electromagnetic) system is an advanced geophysical tool designed for subsurface investigations. It features lead synchronization technology for extended detecting range, integration of functions, and a portable transmitter. With a wireline configuration and surface receiver coils, it offers deep penetration and accurate data collection. The WTEM system is versatile, adaptable to complex terrains, and enables efficient data transfer and analysis. It is widely used in mining, oil and gas exploration, geothermal studies, water resource surveys, and environmental assessments.

MAIN FEATURE

  • Lead synchronization technology for an extended ultra-high power detection range of up to 1000 meters.
  • Integration of multiple functions in a single machine, making it ideal for complex geological environments.
  • IGBT bridge circuit enabling high-power output and quick shut-off, resulting in a portable electromagnetic transmitter.
  • USB port for easy data transfer and enhanced user interaction.
  • Versatile applications in metal mining, coal fields, oil and gas fields, geothermal exploration, water resource surveys, and environmental pollution detection.


APPLICATION

  • Mineral exploration for locating valuable deposits.
  • Oil and gas exploration to identify hydrocarbon reservoirs.
  • Geothermal exploration for characterizing geothermal resources.
  • Groundwater studies for mapping aquifers and assessing water resources.
  • Environmental assessments for detecting and monitoring pollution.
  • Engineering and geotechnical investigations for evaluating subsurface conditions.
  • Archaeological surveys for locating buried structures and artifacts.
