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: 10.1190/geo2022-0608.1
Abstract: Seismic waves always suffer from amplitude dissipation and phase distortion and such attenuation-induced effects will degrade the quality of seismic data. Therefore, a slew of researches on attenuation compensation have been proposed to correct the… read more here.
