Estimation of in situ anisotropy parameters from two perpendicular walkaway VSP lines in South Pars field
(Peer reviewed; Journal article, 2019)Vertical phase slowness and polarization angle are the in situ parameters of P-wave propagation that can be derived from walkaway vertical seismic profiling (VSP) data. To use these data for estimating anisotropy parameters, ... -
Impact of frequency-dependent anisotropy on azimuthal P-wave reflections
(Peer reviewed; Journal article, 2018)Seismic anisotropy has widely been used for the characterization of fractures in a reservoir. Recent work has demonstrated the effect of seismic dispersion on producing a frequency-dependent reflection coefficient, which ... -
Non-orthogonal beam coordinate system wave propagation and reverse time migration
(Peer reviewed; Journal article, 2019)Grid size has a significant influence on the computation efficiency and accuracy of finite-difference seismic modeling and can change the workload of reverse time migration (RTM) remarkably. This paper proposes a non-orthogonal ...
