Commercial, demonstration and pilot geologic CO 2 storage (GCS) projects have provided a
wealth of practical experience in monitoring technologies. In this manuscript we review a few …

Elastic reverse time migration (RTM) can yield accurate subsurface information (eg PP and
PS reflectivity) by imaging the multicomponent seismic data. However, the existing RTM …

Anisotropic and attenuating properties of subsurface media cause amplitude loss and
waveform distortion in seismic wave propagation, resulting in negative influence on seismic …

Least-squares reverse time migration (LSRTM) can provide higher quality images than
conventional reverse time migration, which is helpful to image simultaneous-source data …

Compared with the traditional adjoint migration, the least-squares migration (LSM) can
effectively mitigate the unbalanced illumination and limited resolution associated with finite …

In the correlative least-squares reverse time migration (CLSRTM) scheme, a stacked image
is updated using a gradient-based inversion algorithm. However, CLSRTM experiences the …

Elastic reverse time migration (ERTM) is developed for better characterization of complex
structures by imaging multicomponent seismic data. However, conventional ERTM is subject …

Least-squares reverse time migration (LSRTM) is an iterative inversion algorithm for
estimating the broadband-wavenumber reflectivity model. Although it produces superior …

Elastic least-squares reverse time migration (LSRTM) based on the non-density-perturbation
assumption can generate false-migrated interfaces caused by density variations. We …
