Method and apparatus for reducing induction noise in measurements made with a towed electromagnetic survey system |
摘要 |
A method for reducing motion induced voltage in marine electromagnetic measurements includes measuring an electromagnetic field parameter at least one position along a sensor cable towed through a body of water. Motion of the sensor cable is measured at least one position along the cable; Voltage induced in the cable is estimated from the motion measurements. The measured electromagnetic field parameter is corrected using the estimated voltages.
