Compression Denoising - Using Seismic Compression for Uncoherent Noise Removal

A021 COMPRESSION DENOISING: USING SEISMIC COMPRESSION FOR UNCOHERENT NOISE REMOVAL L. C. DUVAL and V. BUI TRAN IFP Technology Department 1 et 4 avenue de Bois-Préau 95852 Rueil-Malmaison Cedex France E-mail: [email protected] Summary Wavelet related techniques have been proved successful in many seismic processing applications such as filtering or compression. While seismic data compression is not yet widely accepted we propose a compression based on filter banks as a means to remove uncoherent noise from seismic data and thus improve the SNR. Results are demonstrated on synthetic data. Introduction and overview of time-frequency techniques If we let data analysis aside
