An encoder-decoder deep surrogate for reverse time migration in seismic imaging under uncertainty
نویسندگان
چکیده
Seismic imaging faces challenges due to the presence of several uncertainty sources. Uncertainties exist in data measurements, source positioning, and subsurface geophysical properties. Reverse time migration (RTM) is a high-resolution depth approach useful for extracting information such as reservoir localization boundaries. RTM, however, time-consuming data-intensive it requires computing twice wave equation generate store an condition. when embedded quantification algorithm (like Monte Carlo method), shows many-fold increase its computational complexity high input-output dimensionality. In this work, we propose encoder-decoder deep learning surrogate model RTM under uncertainty. Inputs are ensemble velocity fields, expressing uncertainty, outputs seismic images. We show by numerical experimentation that can reproduce images accurately, and, more importantly, propagation from input fields image ensemble.

Bayesian Deep Convolutional Encoder-Decoder Networks for Surrogate Modeling and Uncertainty Quantification
We are interested in the development of surrogate models for uncertainty quantification and propagation in problems governed by stochastic PDEs using a deep convolutional encoder-decoder network in a similar fashion to approaches considered in deep learning for image-to-image regression tasks. Since normal neural networks are data intensive and cannot provide predictive uncertainty, we propose ...

We present a deep learning framework for probabilistic pixel-wise semantic segmentation, which we term Bayesian SegNet. Semantic segmentation is an important tool for visual scene understanding and a meaningful measure of uncertainty is essential for decision making. Our contribution is a practical system which is able to predict pixelwise class labels with a measure of model uncertainty. We ac...
متن کاملTime-shift imaging condition in seismic migration
Seismic imaging based on single-scattering approximation is based on analysis of the match between the source and receiver wavefields at every image location. Wavefields at depth are functions of space and time and are reconstructed from surface data either by integral methods (Kirchhoff migration) or by differential methods (reverse-time or wavefield extrapolation migration). Different methods...

We present a novel and practical deep fully convolutional neural network architecture for semantic pixel-wise segmentation termed SegNet. This core trainable segmentation engine consists of an encoder network, a corresponding decoder network followed by a pixel-wise classification layer. The architecture of the encoder network is topologically identical to the 13 convolutional layers in the VGG...
متن کاملReverse-time-migration of multiply scattered seismic waves
Multiply scattered waves, including internal multiples, are rarely considered as signal when imaging with seismic waves. Reverse-time-migration techniques accurately handle the propagation of such complex scattered waves, but most of these techniques paradoxically do not fully utilize the illumination and energy of multiply scattered waves because these methods rely on the single-scattering ass...
