... can’t meet the need of the high quality imaging. The full azimuth local angle domain gathers retain not only the moveout variations with incident angle but also the azimuthal moveout variations, so the RMOs of different azimuth can be matched with the ray tracing of different azimuth. Therefore...

After several passes of TORT tomographic updates, most CIGs of prestack depth Kirchhoff migration (KPSDM) are flattened arcoss different azimuths. In the subsalt area, we further update...

... of Young's modulus increases. Furthermore, the method of Young's modulus variation with azimuth to predict the fracture orientation is proposed. It contains two steps, Young's modulus inversion for different azimuths of pre-stack seismic data and the ellipse fitting of the Young's moduli in different...

... the accuracy of high-resolution velocity model building. First, we improve the azimuth group binning scheme. Instead of 60° azimuth bin size, we used 20° azimuth bin size. Second, we apply a flexible azimuth-group weighting scheme. In 5D reflection tomography, we use different weights for different azimuths...

First of all, we carry out the work of frequency-dependent AVO inversion in different azimuthal gathers, then we can get different azimuthal dispersive properties; secondly, we use least square ellipse fitting algorithm to fit dispersive properties in different azimuths, thus...

In this paper, we will present an orthorhombic model building flow and demonstrate with the Luda OBC data that our approach can successfully reconcile the structural discrepancies between seismic images from different azimuths and provide a clear and sharp fault image with the WAZ stacking process...
