Patent ID: 8067941

Claim:
A system for streamer electric resistivity survey, which surveys an underground structure below a riverbed using a survey boat, the system comprising: a streamer cable connected to the survey boat and having a plurality of electrodes attached thereto; a multi-channel resistivity meter loaded on the survey boat to measure electric resistivity from the plurality of electrodes attached to the streamer cable; a first RTK GPS (Real Time Kinematic Global Positioning System) loaded on the survey boat to measure a position of the survey boat in real time; and a second RTK GPS installed to a tail of the streamer cable to measure a position of the tail of the streamer cable in real time, the system further including a conductivity meter mounted to a lower portion of the survey boat to measure an electric conductivity of water, and a side scan sonar mounted to the lower portion of the survey boat to measure a water depth.
