Improving full-waveform inversion based on sparse regularisation for geophysical data
Jiahang Li, Hitoshi Mikada, Junichi Takekawa
Full Waveform Inversion (FWI) is an advanced geophysical inversion technique. In fields such as oil exploration and geology, FWI is used for providing images of subsurface structur…
Inexact Augmented Lagrangian Method-Based Full-waveform Inversion with Randomized Singular Value Decomposition
Jiahang Li, Hitoshi Mikada, Junichi Takekawa
Full Waveform Inversion (FWI) is a modeling algorithm used for seismic data processing and subsurface structure inversion. Theoretically, the main advantage of FWI is its ability t…
Improved full-waveform inversion for seismic data in the presence of noise based on the K-support norm
Jiahang Li, Hitoshi Mikada, Junichi Takekawa
Full-waveform inversion (FWI) is known as a seismic data processing method that achieves high-resolution imaging. In the inversion part of the method that brings high resolution in…
Decomposition and utilization of source and receiver ghosts in marine seismic reflection survey data
Hiroaki Ozasa, Hitoshi Mikada
In marine seismic reflection surveys, most data comprise only the pressure acquired by a hydrophone array. The acquired data are subject to frequency bandwidth limitations caused b…
