SYSTEM BASED ON SEISCOMPOSES FOR CONDUCTING UNDERWATER EXPLORATION USING ELECTROMAGNETIC FIELD

摘要

The streamer for conducting a marine electromagnetic survey includes a reference electrode extending substantially the entire length of the streamer. A number of spatially spaced measuring electrodes are placed along the streamer, each of which is electrically isolated from the reference electrode. The voltage measuring circuit is a circuit functionally connected between each measuring electrode and the reference electrode.
