Seismic fault preserving diffusion

WebSeismic noise attenuation with structural features adequately preserved is a fundamental problem in the seismic data processing field. We present a method for noise attenuation based on the anisotropic diffusion of the amplitude field that uses seismic attributes to identify horizons and faults. WebMar 12, 2024 · Our proposed method for seismic data analysis is composed by the following steps: Data augmentation. U-net architecture for train and test data. Data Augmentation. To artificially enhance the size of an actual dataset, data augmentation technics generate different versions of it.

WebIn conventional approach, faults are identified as reflection discontinuity or abruption in post-stack seismic data. In order to highlight fault, several fault attributes by measuring waveform similarity or diversity have been proposed. However, noise and stratigraphic features can also be highlighted in a fault attribute image. WebAbstract Three-dimensional fault interpretation is a time-consuming and tedious task. Huge efforts have been invested in attempts to accelerate this procedure. We present a novel workflow to perform semiautomated fault illumination that uses a discontinuity attribute as input and provides labeled fault surfaces as output. The procedure is modeled after a …
