WebSep 1, 2024 · In this abstract, we propose to use 3D continuous wavelet transform (CWT) to denoise pre-stack seismic data. We first decompose a 3D pre-stack volume to a six-dimensional domain including the space coordinates b= ( bx,by,bz) T, scalar a, dip θ and azimuth ϕ, which can access to the 3D spatial information.

Deep Denoising Autoencoder for Seismic Random Noise Attenuation
WebOct 28, 2024 · Attenuating Random Noise in Seismic Data by a Deep Learning Approach 10/28/2024 ∙ by Xing Zhao, et al. ∙ 20 ∙ share In the geophysical field, seismic noise attenuation has been considered as a critical and long-standing problem, especially for the pre-stack data processing. Here, we propose a model to leverage the deep-learning model … WebFeb 8, 2024 · In the test of synthetic data and complex field data with unknown noise levels, by comparing the noise reduction results of some classic denoising algorithms, the adaptive CNN proposed in this article can more effectively attenuate the noise and reconstruct the seismic waveform. mocsin inc indeed

WebApr 10, 2024 · Road traffic noise is a special kind of high amplitude noise in seismic or acoustic data acquisition around a road network. It is a mixture of several surface waves with different dispersion and harmonic waves. Road traffic noise is mainly generated by passing vehicles on a road. The geophones near the road will record the noise while … WebAs seismic waves travel, they cause an adiabatic pressure perturbation, which causes a temperature change and, potentially, freezing and melting. These cause thermal and compositional diffusion and result in attenuation. Loper and Fearn (1983) derived an expression for frequency-dependent attenuation due to diffusion. WebHighlighted areas show complex and diffracted surface multiples attenuated by our algorithm. Suitable for all survey types: conventional, wide-azimuth, towed-streamer, ocean bottom seismic (OBS), single- and multivessel full azimuth acquisition, and land surveys. in-love-with-paper
