The most promising geophysical imaging tool nowadays is Full Waveform Inversion or FWI. Potentially, FWI can retrieve physical parameters for a whole 3D subsurface volume directly from the seismic data. However, the tool has its limitations, as are the necessity of specially acquired data (low-frequency, long-offset), good initial models and huge computational demands. In our tool, the FWI tool has inherited the efficient implementation of the algorithmically similar RTM and boosted its capabilities in order to turn this very costly imaging algorithm into a commodity.<\/p>\n
Obtaining high-quality 3D models with FWI is a desirable goal that requires clever strategies to make it work seamlessly. Our FWI package includes:<\/p>\n
The resulting models are of very high quality even at deep sections, while the computing costs are not too different from those required for other high-end imaging applications (e.g. RTM). Together with accelerated kernels running on advanced HPC platforms, our tool is mature and ready to reduce uncertainty in seismic exploration surveys today.<\/p>\n
