  • Seismic noise attenuation using adaptive subtraction with improved noise estimation
    Patent number: 11086038
    Abstract: Techniques are disclosed relating to reducing noise in geophysical marine survey data. Such techniques may include adapting an initial set of noise templates to recorded seismic data to generate adapted noise templates and estimating a noise component in the recorded seismic data. The estimating may include determining a degree to which noise and signal components are correlated in the recorded seismic data and masking the recorded seismic data proportionally to the degree of correlation. The adapted noise templates may then be further adapted to a difference between the estimate of the noise component and the noise templates themselves. Resultant noise templates may then be applied to denoise the recorded seismic data.
