Abstract: A method for estimating noise in particle motion seismic recordings and upgoing (deghosted) and downgoing components of ecorded wavefields includes inputting pressure related and particle motion related seismic signals. A sparsity promoting transformation is applied to the input seismic signals. A matrix à and column vector {tilde over (b)} are constructed according to the expression: A ~ = ( I I 0 I - I ? ?

Abstract: A method for deblending seismic signals includes entering as input to a computer recorded signals comprising seismic energy from a plurality of actuations of one or more seismic energy sources. A model of deblended seismic data and a blending matrix are initialized. A blending matrix inversion is performed using the initialized model. The inversion includes using a scaled objective function. The inversion is constrained by a thresholding operator. The thresholding operator is arranged to recover coefficients of the model of the deblended seismic data that are substantially nonzero, against a Gaussian white noise background. The thresholded model is projected into data space. Performing the blending matrix inversion is repeated if a data residual exceeds a selected threshold and the inversion is terminated if the data residual is below the selected threshold. At least one of storing and displaying an output of the blending matrix inversion is performed when the blending matrix inversion is terminated.

Abstract: A method for attenuating multiple reflections from marine seismic signals includes estimating a multichannel prediction filter by minimizing energy between detected seismic signals and seismic signals representing water layer multiple reflections in combination with forcing a sparsity constraint on the estimated multichannel filter. Near offset seismic signals not present in the detected seismic signals are reconstructed by convolving the detected seismic signals with an inverse of the multichannel prediction filter. The multichannel prediction filter is convolved with the reconstructed near offset seismic signals to obtain a final multiple reflection model. The final multiple reflection model is subtracted from the detected seismic signals to obtain multiple reflection attenuated seismic signals.
