VMTU-10 Ground Magnetotelluric Station.

Hardware and software complex for magnetotelluric sounding of the Earth’s crust.

Station VMTU-10 is designed for magnetotelluric sounding.

Station composition:

  • Signal recorder VMTU-10
  • 3 IMS series induction magnetic sensors
  • 5 non-polarizable electrodes
  • Satellite positioning system GPS, GLONASS.
  • 3 shielded isolated signal cables, (Vega patent).
  • 12 v mobile power supply

The sounding depth is from several tens of meters to 10 km.

The VMTU-10 digitally records three mutually orthogonal components of an alternating magnetic field and two components of an electric (telluric) field in a wide frequency range from 0.001 to 20,000 Hz, which makes it possible to carry out electrical exploration at depths from a few tens of meters to several tens of kilometers.

The IMS series induction-type magnetic sensors are precision converters of weak low-frequency magnetic fields into an analog electrical signal.
All sensors provide a maximum output voltage of ± 10 V at a supply voltage of ± 12 V.

IMS sensors in the frequency range up to 100 Hz.

Geoelectric – geophysical section:

As a rule, most of the energy (oil, gas, coal) and mineral resources are located in the earth’s crust.

Hardware and software complex VMTU-10 allows you to
hydrocarbon exploration, which consists of identifying and mapping the rock, structure or trap in the reservoir and its boundaries where hydrocarbons are to be found.
Identifying the reservoir boundary is important because drilling can only be done with prior information about the rock position.
In addition to common structures, others like reef barriers and salt domes are also important structures in which hydrocarbons can accumulate.
VMTU-10 allows exploration of deposits of valuable metals (gold, silver, copper, etc.), revealing the depth and area of ​​their occurrence.
VMTU-10 is also used in the search and mapping of kimberlite pipes, which contain diamonds.
