Seismic full-waveform inversion (FWI) for imaging Earth's interior was introduced in the late
1970s. Its ultimate goal is to use all of the information in a seismogram to understand the …

High-precision seismic imaging is the core task of seismic exploration, guaranteeing the
accuracy of geophysical and geological interpretation. With the development of seismic …

We have developed and implemented a robust and practical scheme for anisotropic 3D
acoustic full-waveform inversion (FWI). We demonstrate this scheme on a field data set …

Full waveform inversion (FWI) is a high-resolution seismic imaging technique that is based
on using the entire content of seismic traces for extracting physical parameters of the …

Least‐squares migration has been shown to improve image quality compared to the
conventional migration method, but its computational cost is often too high to be practical. In …

ABSTRACT A plane-wave least-squares reverse-time migration (LSRTM) is formulated with
a new parameterization, where the migration image of each shot gather is updated …

Conventional multi‐source waveform inversion using an objective function based on the
least‐square misfit cannot be applied to marine streamer acquisition data because of …

Least-squares migration (LSM) has been shown to be able to produce high-quality migration
images, but its computational cost is considered to be too high for practical imaging. We …

摘要介质的黏滞性是普遍存在的. 黏滞性介质中的真振幅成像需要校正由介质的黏滞性引起的
振幅衰减与速度频散, 然而常规的反犙偏移方法存在不稳定问题. 本文在反演的框架下求解黏声 …

Three-dimensional full waveform inversion (FWI) still suffers from prohibitively high
computational costs that arise because of the seismic modeling for multiple sources that is …
