Abstract: Seismic exploration of unconventional hydrocarbon reservoirs (e.g., shale rocks) must take into account the VTI characteristics (transverse isotropy with a vertical axis of symmetry). Prestack inversion for VTI media is more complex than the isotropic… read more here.

DOI: 10.1109/tgrs.2023.3267734
Abstract: Periodic horizontal thin interlayers, or formations developing horizontally layered fractures in a homogeneous background, are commonly studied as a transverse isotropy with a vertical axis of symmetry (VTI) media. Anisotropy needs to be considered in… read more here.

Abstract: Based on an average-derivative method (ADM), we develop an optimal elastic-wave finite-difference nine-point scheme for vertical transversely isotropic (VTI) media in the frequency domain. The optimization coefficients of ADM can be determined by minimizing phase-velocity… read more here.
