Tomography of Diffraction-Based Focusing Operators
Diffractions carry the same kinematic information provided by common focus point operators (CFPOs). Thus CFPO and diffraction time trajectories may be used separately, or combined into a single unified tomography for ...
Comparison of Two Algorithms for Isotropic Elastic P and S Vector Decomposition
(Society of Exploration Geophysicists, 2015-06-10)
P- and S-wavefield separation is necessary to extract PP and PS images from prestack elastic reverse time migrations. Unlike traditional separation methods that use curl and divergence operators, which do not preserve the ...
Estimation of Gas Hydrate and Free Gas Saturation, Concentration, and Distribution from Seismic Data
(Society of Exploration Geophysicists, 2018-08-24)
Gas hydrates contain a major untapped source of energy and are of potential economic importance. The theoretical models to estimate gas hydrate saturation from seismic data predict significantly different acoustic/ elastic ...
