In addition to geothermal exploration, the main application of the system can also be applied to oil and gas, minerals, engineering geology, and carbon storage monitoring and groundwater exploration
The system solves the exploration in the rough terrain area like in Taiwan, where it is difficult to find open sites using the traditional TX loop.
The transmitter coil is about 20 times smaller. In addition to having deeper exploration capabilities,
it also improves the horizontal resolution.

The traditional "Central Loop Transient Electromagnetic Surveying" technique has too large wiring (too large TX coil).
This project develops a central loop transient electromagnetic survey cTEM with extended current waveform linear ramp times.
The main purpose of ELR_cTEM is to use smaller wiring, but with deeper exploration depths.
Develop a complete set of exploration equipment including software and hardware suitable for Taiwan's geophysical exploration, and sell it all over the world.

In order to solve the MT exploration difficulties in the rough terrain and high noisy environment like in Taiwan, 3JTech has developed MT array system and software. After few year’s exploration in Taiwan the results are compared with the drilling results for some unsuccessful geothermal. The MT Array results show no geothermal reservoir around the drilling sites. The results were published in the World Geothermal Congress 2020+1
The separation among the measuring points of the MT array is generally 500 meters to several kilometers. To find geothermal reservoirs, further reservoir simulation requires more accurate data. Generally, microearthquake or background noise is used. However, the method needs to wait for natural earthquakes and sometimes take years.
ERL_TEM exploration system will have a higher horizontal resolution because of the reduced coil span.
