Efficient seismic imaging with the double plane wave data
… the two-way wave equation, can resolve all wavefield propagation phenomena. In geologically complex regions, RTM has been proven to outperform other imaging methods in correctly revealing the subsurface structures. However, implementing the traditional pre-stack shot profile RTM is …

Tensorial elastodynamics and acoustodynamics for generalized seismic migration and inversion applications
… the need to accurately model and reproduce full-wavefield solutions, which represent the main computational effort for such applications as elastic reverse-time migration (E-RTM) and full waveform inversion (E-FWI). However, real-life scenarios often require computing solutions for computational …

Distributed acoustic sensing: modelling, full waveform inversion, and its use in seismic monitoring
… access to the often unrecorded transmission wavefield modes that are crucial to support land full waveform inversion (FWI). The inherently different sampling that DAS fibers provide leads to a requirement for modeling strategies that differ from those used to simulate point sensor data. To …
