Common-Reflection-Point Migration Velocity Analysis of 2D P-Wave Data From TTI Media
(Soc Exploration Geophysicists, 2014-05)
We have developed a common-reflection-point (CRP)-based kinematic migration velocity analysis for 2D P-wave reflection data to estimate the four transversely isotropic (TI) parameters VPo, δ, and ε, and the tilt angle ϕ ...
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 ...
Time-Domain Least-Squares Migration Using the Gaussian Beam Summation Method
With a finite recording aperture, a limited source spectrum and unbalanced illumination, traditional imaging methods are insufficient to generate satisfactory depth profiles with high resolution and high amplitude fidelity. ...
