Electromagnetic geophysical survey systems and methods employing electric potential mapping |
摘要 |
The present disclosure describes various geophysical survey systems and methods for mapping an electric potential field. At least one illustrative embodiment includes an electromagnetic (EM) source and geophysical survey cables that each includes multiple electrodes spaced apart along each geophysical survey cable's length, and multiple data acquisition units that each obtains measurements indicative of an electric potential between two the electrodes. A modeling module is included and configured to calculate a reference potential at a selected electrode for each of the plurality of geophysical survey cables, as well as a calculation module to combine signals representative of the measurements to produce signals indicative of the electric potential of each electrode relative to the reference potential. 10-6 _ E-FIELD -12 WATER STRATA AIR MAGNITUDE DOMINATES DOMINATES DOMINATES (V/(A-m) 10-14 301 302 303 10-16 10-18 103 104 105 SOURCE TO RECEIVER RANGE (METERS) ANALOG DETECTION DIGITAL DETECTION OUTPUT SIGNAL OUTPUT SIGNAL 200m 201- ADC |
