For an example implementation of 3D Full-waveform inversion, please see the example in tests/fwi3d. Note that this requires users to provide an external 3D FWI code to calculate misfit values and gradients. See details in forward/fwi3d. References Zhang, X., & Curtis, A. (2024). VIP-Var...
In this paper, PyFWI is presented which is a Python package for performing full-waveform inversion and time-lapse full-waveform inversion. To mitigate some challenges inherent to these problems, PyFWI provides different options such as different types of regularization, multi-scale strategy, gradient...
Code implementation The proposed seismic inversion algorithm was implemented in Python (version 3.9). We used PyTorch with CUDA (versions 1.13 and 11.7) for the W-Net GAN model and training code. The training was conducted on a computer running Windows 11 operating system, with Intel® Core...

Here, we give a description from a user’s and programmer’s perspective of the highly modular, flexible and extendable software package ASKI–Analysis of Sensitivity and Kernel Inversion–recently developed for iterative scattering-integral-based seismic full waveform inversion. In ASKI, the three ...
SeisFlows is an open-source, Python-based waveform inversion package that tackles the problems of full waveform inversion, seismic migration, and adjoint tomography. With a user base in both academia and industry, this package has been used for production scale inversions, some with over a billion...

Full waveform inversion (FWI) provides high-resolution velocity models by exploiting the complete information embedded in the received seismic waveforms. However, FWI's advantage comes at the risk of local minimum and non-convergence when there is insufficient information about the large-scale or low...
