Due to the periodicity and rhythmicity of sedimentation, short-term cycles are commonly developed in sedimentary strata. Under the assumption of a long seismic wavelength, such strata can be regarded as a seismic single thin bed with vertical transversely isotropic (VTI) characteristics. A thin interbed can be formed by the stacking of a series of isotropic and VTI single thin beds. In seismic inversion,...
Thin interbeds are typical reservoirs in eastern China. Thin layers and fractures bring huge challenge to fluid identification in anisotropic reservoir. This study focuses on thin-fractured reservoirs and amplitude attributes of shear-wave splitting, and consequently predicted fluid type in fractured reservoir based on the response of fast and slow S-waves to fluids. 3D HTI viscoelastic equation was...
