Physics-Guided Data-Driven Seismic Full-Waveform Inversion: …
WebbResults indicate that the predictions of the trained network are susceptible to facies proportions, the rock-physics model, and source-wavelet parameters used in the training data set. Finally, we apply CNN inversion on the Volve field data set from offshore Norway. WebbCurrently, most seismic inversion problems are addressed by: physics-driven seismic inversion based on adjoint theory (commonly used in the geophysical community). This method attempts to minimize iteratively a cost function defined by the differences between the observed and calculated data (e.g., \(l^2\)-norm). iphone mail icon missing
Convolutional neural network for seismic impedance inversion
WebbDeep learning-based methods gain great popularity because of their powerful ability to obtain exact solutions for geophysical inverse problems. However, those deep learning methods that use seismic data as the only input lead to difficult training and unstable inversion results (i.e., transverse discontinuity or geologic unreliability). Webbgreater generalization ability than purely physics-based and purely data-driven approaches. 1 Introduction Seismic full-waveform inversion (FWI) attempts to reconstruct an image of the subsurface geology from measurements of natural or artificially produced seismic waves that have travelled through the subsurface.
