MT AMT Oil and Gas Exploration

We provide cost-effective geophysical solutions in hostile environments, such as those characterized by complex thrust belt tectonics, 

Sig2shallow volcanics, outcropping carbonates, or sub-salt.

 

In such environments, the conventional seismic methods often provide marginal results and new exploration approaches need to be defined.

To Magnetotellurics MT / AMT, the conditions which cause difficult seismic energy propagation are largely irrelevant and so the method readily images the resistivity of the sub-surface.

 

Ideal targets include resistive carbonate reservoirs below shale or flysch and clastic reservoirs below salt bodies. Integration of seismic, gravity and magnetotellurics MT leads to improved velocity-model building for outcropping carbonates, thrust sheets, sub-basalt, and sub-salt for seismic, passive seismic (IPSS and PST)  imaging, as well as to better resistivity estimates for magnetotellurics MT interpretation.

 

MT Magnetotellurics – Geothermal Exploration

The contrast of resistivity provides an excellent tool for identifying geothermal targets.

 

Acquisition systems are based on lightweight 24-bit 5-channel GPS-synchronized recording units covering the frequency range from 0 to 50 kHz.

 

The data acquisition system has  a receiver unit (Unit MT), two electromagnetic sensors, and four electrodes  the placement of 4 electrodes arranged in a cross the disposition of the two orthogonal magnetic sensors at a distance of about 25 m from the instrument receiver.

 

 Magnetotellurics MT / AMT Key Advantages and Benefits 

The magnetotellurics surveys reach great depths in confined spaces.
