The Petro-Sonde utilizes the naturally occurring telluric current (1 Hz or less) which flows in the upper part of the Earth's crust to study the subsurface. Basic laws of physics are applied to analyze the telluric electric field at the surface to obtain the desired subsurface information. Electrotelluric technology has the unique ability ...

Drilling is the traditional and still the most common method used in coal exploration. Most coal companies rely heavily on borehole data to evaluate their mine properties. However for the Underground Coal Gasification (UCG) and Coal Bed Methane (CBM) it is necessary to map the subsurface coal and to detect other spatial properties of the coal seam with a high degree of accuracy. Here the ...
