RECEIVER STREAMER SYSTEM AND METHOD FOR MARINE ELECTROMAGNETIC SURVEYING

摘要

A RECEIVER STREAMER SYSTEM [300] FOR MARINE ELECTROMAGNETIC SURVEYING INCLUDES A FIRST STREAMER [302], AND A SECOND STREAMER [302] DISPOSED SUBSTANTIALLY PARALLEL TO AND SPACED APART FROM THE FIRST STREAMER [302]. A FIRST PAIR OF ELECTRODES [306] IS ASSOCIATED WITH THE FIRST STREAMER [302] AND A SECOND PAIR OF ELECTRODES [306] IS ASSOCIATED WITH THE SECOND STREAMER [302]. EACH OF THE FIRST AND SECOND PAIRS OF ELECTRODES [306] IS FUNCTIONALLY ASSOCIATED WITH A VOLTAGE MEASURING CIRCUIT CONFIGURED TO MEASURE VOLTAGE ALONG AN INLINE DIRECTION. AT LEAST ONE ELECTRODE [306] ON EACH OF THE FIRST AND SECOND STREAMER [302] IS CONFIGURED AND ASSOCIATED WITH A VOLTAGE MEASURING CIRCUIT TO MAKE VOLTAGE MEASUREMENTS IN A CROSS-LINE DIRECTION.
