Simultaneous reconstruction and denoising for DAS-VSP seismic data by RRU-net

نویسندگان

چکیده

Distributed acoustic sensing in vertical seismic profile (DAS-VSP) acquisition plays an important role reservoir monitoring. But the field data can be noisy and associated with missing traces which affects imaging geological interpretation. Therefore, DAS-VSP reconstruction a high signal-to-noise ratio (SNR) is worth studying. There are no exact relationships between signals noise t-x domain data, means that reconstructing suppressing simultaneously by deep neural network difficult. We develop novel algorithm based on U-net combination Hankel matrix as input/output, rather than data. The frequency of proposed to facilitate denoising rank reduction problem high-rank matrix. matrices incomplete ones while those complete without low-rank ones, beneficial learning. In our (RRU-net), two-channel input/output layers designed for real imaginary parts domain. Thus, reconstructed precision SNR could obtained using trained RRU-net. Meanwhile, we tested RRU-net two synthetic one results show effectiveness feasibility method. Our performs better both U-net-based method uses t?x approach.

An open-source Matlab code package for improved rank-reduction 3D seismic data denoising and reconstruction

Simultaneous seismic data denoising and reconstruction is a currently popular research subject in modern reflection seismology. Traditional rank-reduction based 3D seismic data denoising and reconstruction algorithm will cause strong residual noise in the reconstructed data and thus affect the following processing and interpretation tasks. In this paper, we propose an improved rank-reduction me...

Fast, simultaneous and robust VLF-EM data denoising and reconstruction via multivariate empirical mode decomposition

The measurement of Very Low Frequency Electromagnetic (VLF-EM) is important in many different applications, i.e, environmental, archeological, geotechnical studies, etc. In recent years, improving and enhancing VLF-EM data containing complex numbers (bivariate) was presented by several authors in order to produce reliable models, generally using univariate empirical mode decomposition (EMD). Ap...

Seismic data denoising through multiscale and sparsity-promoting dictionary learning

Seismic data comprise many traces that provide a spatiotemporal sampling of the reflected wavefield. However, such informationmay suffer from ambient and random noise during acquisition, which could possibly limit the use of seismic data in reservoir locating. Traditionally, fixed transforms are used to separate the noise from the data by exploiting their different characteristics in a transfor...

An Efficient Algorithm for General 3D-Seismic Body Waves (SSP and VSP Applications)

Abstract The ray series method may be generalized using a ray centered coordinate system for general 3D-heterogeneous media. This method is useful for Amplitude Versus Offset (AVO) seismic modeling, seismic analysis, interpretational purposes, and comparison with seismic field observations.For each central ray (constant ray parameter), the kinematic (the eikonal) and dynamic ray tracing system ...
