Pdf Vector Based Elastic Reverse Time Migration Based On Proposed Pdf | on aug 17, 2017, xiaoyu zhang and others published vector based elastic reverse time migration based on proposed energy normed imaging condition | find, read and cite all. We have created a new 2d migration context for isotropic, elastic rtm, which included decomposition of the elastic source and receiver wavefields into p and s wave vectors by decoupled elastodynamic extrapolation, which retained the same stress and particle velocity components as the input data.

Github Geophysicslab 2d And 3d Elastic Reverse Time Migration 2d And Numerical examples on simple three layered model and marmosui2 model demonstrate that the proposed ertm with the proposed imaging condition can provide relatively accurate images with the clear physical meaning. The proposed imaging condition accounts for the directionality of wavefields in space and time, outputs the total reflection energy including kinetic and potential energy, and attenuates the backscattering artifacts. Abstract 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 and amplitude information. Numerical examples demonstrate that the proposed ertm method can provide accurate images with clear physical meaning. however, there is still ample room for further investigation and exploration in this field.

Semantic scholar extracted view of "vector based elastic reverse time migration based on proposed energy normed imaging condition" by xiaoyu zhang et al. Abstract the scalar images (pp, ps, sp, and ss) of elastic reverse time migration (ertm) can be generated by applying an imaging condition as crosscorrelation of pure wave modes. 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. Aimed to address the polarity reversal problems caused by helmholtz decomposition applied in wavefield separation of conventional ertm, a vector based ertm (vb ertm) method has been.
