Power line noise attenuation in seismic data using spectral interpolation

Authors

Abstract

Due to high cost of data gathering and in order to increase the quality of the data, the most important challenge in seismic data de-noising is maximum attenuation of seismic noise with minimum signal leakage to achieve maximum signal-to-noise ratio. Power line or fixed-frequency harmonic noise in the frequency range of 50 to 60 Hz is one of the factors that contributes to decrease seismic signal quality, and also, reduces signal-to-noise ratio. This occurs through a frequency interference of a harmonic in the natural frequency range of the power lines (50 to 60 Hz) with the seismic signal frequencies.
