Abstract:
Disclosed are methods and systems for suppression of noise in electromagnetic surveying that includes stacking two or more frames of electromagnetic data. An example embodiment discloses a method for suppressing swell-induced noise in an electromagnetic survey, comprising: measuring an electromagnetic field parameter at one or more positions to provide an electromagnetic signal, the electromagnetic signal comprising a swell-induced portion; and stacking two or more frames of the electromagnetic signal to provide a stacked signal in which the swell-induced portion is suppressed, wherein the swell-induced portion is out of phase between the two or more frames.
