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 ...
Up/Down and P/S Decompositions of Elastic Wavefields Using Complex Seismic Traces with Applications to Calculating Poynting Vectors and Angle-Domain Common-Image Gathers from Reverse Time Migrations
(Society of Exploration Geophysicists, 2018-06-01)
Separations of up- and down-going as well as of P- and S-waves are often a part of processing of multicomponent recorded data and propagating wavefields. Most previous methods for separating up/down propagating wavefields ...
Vector-Based Elastic Reverse Time Migration
(Society of Exploration Geophysicists, 2015-10-15)
Prestack elastic reverse time migration (RTM) of multicomponent seismic data requires separating PP and PS reflections before, or as part of, applying the image condition, and using image conditions that preserve the angle ...
