Pdf Vector Based Elastic Reverse Time Migration Elastic reverse time migration (rtm) has the ability to retrieve accurately migrated images of complex subsurface structures by imaging the multicomponent seismic data. 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.
Figure 1 From Pure P And S Wave Elastic Reverse Time Migration With 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. 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. Figure 1 | sign distributions of pp images via the opening angles. the green arrows and blue arrows represent the p wave incident vectors of the source wavefield and the reflected vectors of the receiver wavefield, respectively. 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.

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. To address this issue, we propose a vector wavefield decoupling method tailored for fluid solid coupled media, aiming to achieve more accurate elastic vector wave imaging for ocean bottom node (obn) data. Therefore, we propose a converted decoupled wave equation to derive decoupled and converted wavefields that incorporate the s wave stress component. for the vector based wavefields, scalar decoupled imaging conditions based on the energy norm are established. 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.
