A complex point-source solution of the acoustic eikonal equation for Gaussian beams in transversely isotropic media
(Peer reviewed; Journal article, 2020-03-11)The complex traveltime solutions of the complex eikonal equation are the basis of inhomogeneous plane-wave seismic imaging methods, such as Gaussian beam migration and tomography. We present the analytic approximations for ... -
Diagnostics of seismic time-lapse effects of sandstones based on laboratory data
(Peer reviewed; Journal article, 2014-09)We evaluated a viscoelastic modeling of P- and S-wave velocity dispersion, attenuation, pressure, and fluid effects for a set of siliciclastic rock samples. Our analysis used a published laboratory data set of 63 sandstones ... -
Modeling compaction effects on the elastic properties of clay-water composites
(Peer reviewed; Journal article, 2012-09)Modeling the elastic properties of clay-bearing rocks (shales) requires thorough knowledge of the mineral constituents, their elastic properties, pore space microstructure, and orientations of clay platelets. Information ...
