Seismic trace noise removal by smoothed SureShrink
Vargas, R.N. and Veiga, A.C.P., 2020. Seismic trace noise removal by smoothed SureShrink. Journal of Seismic Exploration, 29: 363-370. Seismic traces are usually corrupted by Additive White Gaussian Noise (AWGN). AWGN hinders the evaluation of seismic attributes and can lead to distortions during seismic interpretation. Therefore, the development of methods that can effectively remove the noise and extract the signal from the seismic trace is critical. Here we propose a new seismic trace noise removal method called SureShrinkWin, which evaluates the estimates obtained by the SureShrink method when SureShrink is applied in signal windows. To validate the efficacy of the SureShrinkWin method, we performed a Monte Carlo Simulation that considered sixteen seismic traces that were obtained from the astsa R package.
