To Survey Underground Conditions

We are the first company that has introduced and implemented a commercial magnetotelluric (MT) survey in Japan. We recently used the MT method to explore an area under the sea floor at a depth of 5,000 meters or more.

At any desired depth from a few meters to tens of kilometers, we can use electromagnetic waves (such as MT, CSAMT, and TEM) or elastic waves (such as seismic reflection method, VSP, and crosshole tomography) to investigate the geophysical structure and properties of the surface and borehole.

We have electromagnetic methods based on 2D and 3D analyzing technologies and offer exploratory services (such as exploration, data processing, and analysis) for a wide range of applications. Examples of our services include groundwater and environment surveys at depths from several meters to tens of meters, the prospecting of hot springs or metallic deposits at about 1,000 meters deep, the exploration of geothermal energy and oil at several kilometers, and scientific or under-sea floor investigation at 10 kilometers or deeper.

We are now involved in the development of CSEM (Controlled Source EM) for shallow areas under the sea floor.
