Magnetotellurics

Magnetotellurics illustrate the distribution of the electric conductivity in the underground. It is one of the methods of geophysical exploration applied most often internationally in deep geothermics. Compared to seismic exploration, these measurements are clearly more cost-effective and easier.

By means of magnetotellurics, temporal variations of the magnetic and electric field of the Earth are measured. The method is non-invasive and does not require any active transmitters. Thus, it can be applied in a relatively cost-effective manner and with moderate resource requirements. Within densely populated areas, interfering signals may have an impact on the measurements. That is why the use of magnetotellurics should be assessed on a case-by-case basis.

GTN offers the following services:

• Evaluation of existing measurements, models and reports
• Planning and monitoring of new measurements
• Modelling of magnetotelluric data
