Characterization of Geotomographic Studies with the EMRE System
Figure 1
The EMRE device and measurement geometry (not to scale). The mobile receiver takes measurements during movement at a frequency of 2 Hz ( ~0.25 m, ~30 m/min), while the stable transmitter transmits continuously (312.5, 625, 1250, 2500 kHz). The attenuation distribution of the borehole section is reconstructed (dB/m), a red colour corresponding to higher attenuation.
